7 Reasons Why Your Air Compressor is Losing Pressure and How to Fix It

by vemcoblogs -
Air Compressor

Industrial processes invest a substantial portion of their operational expenses in compressing air. But if your compressor is losing pressure, it means a waste of electricity, higher costs and lower profit margins. It also means your compressor is working harder to maintain the pressure and thus going through more wear and tear. Any compressor dealer in Mumbai will tell you the importance of maintaining optimum air pressure in a compressor. 

In This Blog, We Take You Through 7 Main Reasons Why Your Air Compressor Could Be Losing Pressure And How To Fix It:

  • Leaks In The Air System

Ruptures in hoses, piping trees, nozzles and connectors connecting your air compressor and pneumatic tools cause leakage of air. This inevitably leads to a drop in air pressure. To avoid this problem, get your compressor systems regularly inspected for ruptures and leaks by VEMC –– the leading ELGi Air Compressor Dealers in Mumbai.

  • Faulty pressure regulator

Regulators control the passage of air through your air compressor systems. A faulty, sub-optimal or undersized pressure regulator can cause a drop in air pressure. Always ensure you are choosing the right-sized pressure regulator for your compressor. Also, do not suppress your regulator to compensate for lost pressure. This can cause it to become unresponsive in the long run. Whenever there’s an inexplicable drop in pressure, get your pressure regulator inspected by your nearest Air Compressor Dealers in Mumbai.

  • Inadequate Air Intake

Another highly likely reason could be that your air compressor is simply not taking in enough air from the inlet. Get this problem fixed by inspecting, cleaning and removing any physical barriers to air at the inlet.

  • Worn or damaged valves

There will always be a slight drop in pressure as soon as the air enters the valves since the momentum is interrupted. This can get worse in case your valves are worn out or damaged. Always keep the air compressors in good working condition by having an effective maintenance regime in place. 

  • Clogged Or Dirty Filters

Just like in your car, air compressor filters can get dirty due to dust or other particulates over a period of time, especially in factory or workshop settings. Dirty or clogged filters can rob your air compressor of fresh air which inevitably leads to a drop in pressure. The solution of course is regular clean-up and replacement of air filters.

  • Malfunctioning Pressure Switch

In case the pressure switch fails or malfunctions, it gets very difficult for the air compressor to maintain the pressure. Get the switch inspected and repaired in case air pressure keeps dropping inexplicably.

  • Insufficient Lubrication

Finally, insufficient lubrication in the air compressor system can be another cause of a drop in air pressure. Air compressors need optimally sized lubricators. In case yours aren’t performing up to the mark or aren’t supporting the load, get them replaced. Get lubricators that have the best ratings for maximum pressure drop reduction.

Why Air Compressor Dryers Are Essential

by vemcoblogs -
Air Compressor

Atmospheric air always contains a certain amount of moisture. When this air goes through rapid pressure changes through a compressor, this moisture precipitates as a condensate. This can be potentially harmful not just to your air compressor itself but also to your business operations. Moisture in your food processing or packaging business can encourage the growth of microorganisms, thus causing spoilage and quality concerns. Moisture also speeds up the process of corrosion in metallic parts leading to higher repair and maintenance costs. Vemc Is The Leading Air Compressor Dealer In Mumbai.

In This Blog, We Explain Why Air Compressor Dryers Are Essential And Which Type Of Compressors Suit Your Needs The Best:

  • The Need To Dry Compressed Air:

When air is compressed, the water vapour condenses and starts flowing into the pipes. The point at which the vapours start condensing is called Pressure Dew Point (PDP). This can cause serious issues with pipes and the connected equipment over a period of time, and thus the compressed air needs to be dried. This can be achieved by using either an integrated aftercooler or standalone drying equipment. 

Whether you use an aftercooler or augment your compressor with a standalone dryer depends entirely upon your business requirement. VEMC as the top Elgi Compressor Dealer in Mumbai can provide you with all the relevant information and also supply the equipment as per your need. 

  • Two Main Dryer Types:

As any compressor dealer in Mumbai will brief you, two main types of compressed air dryers are available in the market. Which one you choose depends upon your need, budget and business application.

  1. Refrigerant Dryers

This is one of the most cost-effective solutions to your problems. A refrigerant dryer provides air drying through cooling (as the name suggests). By cooling the air intensely, these dryers try to achieve the dew point at temperatures between 2-10 (C). This makes them highly energy efficient. Besides, the refrigerant gases used in equipment these days are more sustainable and environment-friendly. Get in touch with your nearest Elgi compressor dealer in Mumbai to know whether refrigerant dryers are right for your business operations.

  1. Desiccant/Adsorption Dryers

These air dryers are slightly expensive but at the same time more energy efficient and effective in removing moisture from the air. These work through a chemical process which binds to the moist air and removes it. These dryers can attain dew point at temperatures as low as -40(C). 

Conclusion

Following the right procedures to dispose of condensate is necessary for your business as well as the environment. The moisture often contains tiny oil particles invisible to the naked eye. These need to be removed using an oil/water separator. Otherwise, you could incur fines or penalties for violating environmental guidelines.

How to Use an Air Compressor: Things to Consider

by vemcoblogs -
Air Compressor

Air compressors are used for a variety of applications across industries. This is because of the enormous amount of power that compressed air generates. Compressed air when focused and channelised in the proper way can be used to accomplish tasks like cleaning, drilling, pumping etc. in an effective and efficient way. VEMC is the leading air compressor dealer in Mumbai and in this blog, we explain how best to use your air compressor.

Picking The Right Compressor For Your Needs:

It all begins with selecting the right compressor for your business operations. For instance, if you are using the compressor simply for cleaning tasks, a portable compressor without a tank will fully suffice. In case you wish to perform heavy-duty tasks, this obviously won’t be enough and you may have to look for a more powerful compressor. Likewise, you may also want to check out whether the reciprocating or rotary air compressor is better suited for your tasks. A quick call or visit to VEMC –– the authorised Elgi Air Compressor Dealers in Mumbai can help you choose better!

  • Getting started

Find the ideal position for your compressor. Make sure the floor is sturdy and can resist the load and vibrations from the compressor while it is at work.

  • Oil And Air Intake

Make sure the compressor has enough oil. Manually remove the oil cap and add the oil if it isn’t up to the specified mark. An adequate amount of oil keeps the compressor parts in good health by avoiding unnecessary friction.

Next, turn the switch on and fill the air tank. This should also get the PSI needle going. Set the PSI that you will be needing for the operation. Make sure the drain valve is tightly closed. Your nearest compressor dealer in Mumbai can definitely help you with these manual nitty-gritties. 

  • Moisture And Drainage

Moisture can speed up the process of rusting and corrosion, thus affecting the working life of your compressor. This naturally has implications for your maintenance, repair and replacement costs. Besides, moisture can also encourage the growth of microbes and cause spoilage of food or other sensitive inventory. Regular drainage of moisture is therefore necessary. This might call for some help from your nearest ELGi Air Compressor Dealers in Mumbai, but in most models, the drain valve is located at the bottom of the tank.

  • Power

Connect the air compressor to a three-pin power source. For your personal safety and to avoid damage to equipment due to high voltage, always make sure your compressor is grounded. As much as possible, avoid using extension cords and instead use an additional air hose to increase your reach. This is because extension cords can cause your compressor to overheat.

  • Meeting All Safety Regulations

Use goggles and closed-toe shoes to protect your eyes and feet from impact while using an air compressor. To ensure the safety valve is functioning properly, test it by tugging on it before use and listening to the air escaping.

Advanced Benefits Of A Rotary Screw Air Compressor

by vemcoblogs -

Rotary screw compressors bring in a host of benefits to your business –– technical, economical and utilitarian. These are highly energy-efficient air compressors and also very adaptable, thanks to their variable speed control. An ELGi Screw Compressor is in fact significantly superior to any of the piston air compressors you can find out there. 

In This Blog, We Take You Through Some Of The Most Advanced Benefits You Get With A Rotary Screw Air Compressor:

 Rotary Screw Air Compressors Vs. Piston

With respect to the engine arrangements, a rotary screw compressor brings you wide diversity as compared to the piston compressor. Piston compressors simply use pistons to pressurise air and move it from one cylinder to another, compressing it in the process.

Rotary screw air compressors like ELGi Screw Compressor bring the best technology to the table. This completely eliminates the friction when the engine spins and makes downtime almost non-existent.

That said, the initial investment is somewhat on the higher side. However, the benefits that rotary screw air compressors bring along quickly cover these initial one-time costs.

 Choosing The Right Motor And Compressor Size

Direct-drive compressors are usually more efficient than belt-drive and gear-drive compressors. But again, it depends on your budget. When it comes to sizing your compressor, choose on the basis of the air pressure you would require throughout the day. If you’re unable to decide the type and size of your compressor, you can always get in touch with VEMC –– a leading air compressor dealer in Mumbai.

Technology And Equipment Considerations

With rotary screw compressors, maintenance is incredibly simple. ELGi Screw Compressor offers single-service door access to routine maintenance points. They also have spin-on oil filters and separator elements for quick and easy routine service. 

When To Replace And Upgrade

You may be hesitant about replacing your existing air compressor with a rotary screw air compressor,  especially if it is in a good condition. But as a thumb rule, you must look to replace your equipment after 10 years or so. This is to be abreast of all the innovations and efficiencies brought about by advancing technology. Often running older equipment can be more expensive than using new ones due to innate inefficiencies or wear and tear. 

Environmental Impact

ELGi Screw Compressors are specially designed to reduce running costs and environmental impact. Variable Speed Drives (VSD) for one reduce energy loss significantly. With IoT-based applications, compressors can be connected to their owners through a mobile app, thus ensuring monitoring and predictive maintenance. Overall, ELGi as an organization is committed to addressing climate change and building a long-term sustainability roadmap.

What Size of Industrial Air Compressor do I Need?

by vemcoblogs -

One of the most challenging decisions while buying an air compressor is sizing it. This is necessary for maximum efficiency and involves a number of parameters such as CFM, pressure, application, layout, etc. While sizing an air compressor may seem simple on the surface, it is determined by a host of factors to ensure optimum performance. As we are one of the leading Air Compressor Dealers in Mumbai.

In This Article, We Can Take You Through All Of These That Shape The Sizing Decision Of Your Industrial Air Compressor:

Size of your project

Quite simply, bigger the size, more will be the power generated. Whether you need your air compressor for heavy-duty construction work or office work will be the primary determinant of your sizing decision. Besides, if you need a constant flow, it will be better to invest in a large-sized air compressor as small compressors are not able to generate it.

Your tools and applications

Next, you’ll have to consider the work you’re going to perform with your air compressor. Air compressors have wide-ranging applications from drilling to sand-blasting. Choosing the right size for the right task is critical to ensure effectiveness. All tools have a required flow or CFM which should be matched with that generated by your air compressor. An ELGi Reciprocating Compressor is a great option for both light and heavy-duty use.

Your source of power

A standard domestic voltage should be enough for most compressors to work. But for larger industrial compressors, a 240-volt source is necessary. Where electricity isn’t available, compressors can also be powered with petrol. Since your source of power acts as an important constraint in the functioning of your compressor, take it into serious consideration before choosing one.

Space available

If you’re trying to buy an air compressor for your garage startup, there’s very little hope that a large industrial compressor will fit in there. Given the paucity of space in the city, most air compressor dealers in Mumbai will emphasize on the space constraint as the number one factor to size your compressor. Besides, if you’re going to move the compressor frequently, a smaller and lighter one will always be the better choice to avoid inflating your carriage and labour bills.

Size of the tank

The size of the tank is the most important factor that decides the size of an air compressor. This is significant because it determines how long you use the compressor before it needs to refill the air tank. If your tools and applications require a constant flow, a bigger air compressor is the right choice. Smaller tools like nail gun require short bursts of compressed air that don’t need a large tank. But the motor will have to switch on and off, which can cause wear and tear, and affect the lifespan of your compressor overall.

Conclusion 

Our expertise and experience make us one of the topmost air compressor dealers in Mumbai. If you’re specially looking for ELGi Air Compressor Dealers in Mumbai, we are the perfect choice for you. Dial us at 022 43436655 or email us at marketing@vemc.co.in to get in touch today!

How To Improve The Compressor Efficiency

by vemcoblogs -

Low-efficiency levels can seriously impact the operational costs of your business, as you will have to foot much higher energy bills, in return for some sub-optimal performance from your air compressor. As your air compressor dealers will tell you, most compressors usually have ample scope for improvement in terms of efficiency. VEMC as a top compressor dealer in Mumbai can share some insights from its vast experience.

What are the do’s and don’ts to achieve high availability with maximum efficiency?

Compressor installation:

Make sure you choose a spot that has clean dust-free air and also sufficient space for unloading, installation, and regular maintenance. The surface must be level and one that can withstand the load of the compressor. Ensure the compressor is protected from rain, sun, hot air, flammable material, and corrosive agents.

Regular check-ups of machine parameters:

Air compressors have a few critical parameters, such as capacity, pressure, temperature, etc. To ensure that the air compressor is performing at optimum levels, it is very necessary that these parameters are inspected at regular intervals. Any AMC service provider or reputed compressor dealer in Mumbai can be helpful on this front.

Proper maintenance plan:

Preventative maintenance is important to not just boost the efficiency of your Elgi compressor but also avoid breakdown costs.

  • Air leaks –– Never ignore the air leaks, no matter how insignificant they seem. Air leakage can cause serious loss of pressure and wastage of energy.
  • Change filters regularly –– Contaminants in the air such as dirt, dust, or grease, can lead to a drop in air pressure, and a rise in energy consumption. To maintain pressure levels, change your air compressor filters regularly.
  • Maintenance regimes –– Be sure that a comprehensive procedure and checklists are in place, and that your employees are trained in executing proper maintenance. Air compressor dealers and AMC service companies can guide you well on this.

Proper selection of ancillaries:

Unauthorised or generic ancillaries such as dryers, pipes, and filters, may not fit or work well with the air compressor, and instead cause damage to the system and reduce its life span. Always procure them only from an authorized Elgi compressor dealer.

Does a maintenance plan affect my compressors’ efficiency and availability?

As much as possible, follow the recommendations from your air compressor dealer. With a good maintenance plan in place, you simply don’t need to worry about parts, inventory, monitoring, and repairs. It helps you make the most of your investment and effectively manage resources. Therefore, a proper maintenance plan from a reputed AMC services company can significantly boost your compressors’ efficiency and availability.

Are there advanced ways to monitor my equipment?

You cannot possibly see what is happening on the inside of your Elgi air compressors. But parameters like temperature and pressure can tell you a great deal about its health. Any parameter going out of the acceptable range naturally indicates that the air compressor might malfunction, or at the very least, the efficiency levels are affected.

Compressed Air Industry Trends

As more and more companies become energy and cost-sensitive, compressed air will emerge as one of the most favored ways to power tasks in factories and homes. In this blog, we take you through some of the most significant compressed air trends that customers and air compressor dealers must watch in 2023.

Here are the trends in the compressed air industry to look out for in 2023

1. Demand for Compressed Air Equipment Remains High

Compressed air is often the 3rd or 4th most favored utility in the manufacturing industry. As per a market analysis report, the global air compressor market stood at $32.02 billion in 2020 and is expected to grow at a CAGR of 3.4% from 2021 to 2028. Although the growth was somewhat tempered by the pandemic which caused a general slowdown across sectors, the post-pandemic world is ever more focused on energy efficiency, reducing costs, and cutting CO2 emissions. With the growing standard of living especially in the Asia-Pacific region, air compressors will see plenty of demand due to the rising use of air conditioners.

2. Lead Times Remain Longer than Normal – Especially for Steel Parts

A number of factors can affect the lead times of spare parts such as demand, stockouts, shipping delays, inefficient inventory control, and unnecessary processes. An Elgi compressor with its sophisticated design is made up of a number of small and large components. 

When it comes to the spare parts of your air compressors, you might experience longer than normal lead times. This is because most industries are just reopening after the pandemic, and with a sudden spurt in demand, mills will be looking to complete orders of priority sectors ahead of manufacturers of air compressor parts. This being a classic demand-supply problem, might even affect the prices of the spare parts, causing a bit of a concern to customers as well as air compressor dealers.

3. Compressed Air Supply Chains and Prices Are Stabilising

Compressor dealers have witnessed a serious disruption in business due to the pandemic. The complex designs and assemblage of a number of parts sourced from different manufacturers could make logistics for a typical Elgi compressor dealer rather challenging. But as the pandemic ebbs away, the global economy is recovering fast, most Elgi air compressor distributors would expect the supply chains and prices to stabilize once again.

4. Industrial Internet of Things (IIoT) Applications Are Coming for Compressed Air

The Industrial Internet of Things (IIoT) will have massive implications for preventative maintenance, performance tracking, and energy efficiency. Air compressors communicating over the internet can share the condition of their parts such as belts and motors. The enormous amount of data produced as a result will be handy in designing energy-efficient and high-performing air compressors. Monitoring will become remote and convenient as parameters like flow, pressure, speed, etc. will be available on mobile devices.

8 Ways To Improve The Efficiency Of Your Compressed Air System

by vemcoblogs -
Improve The Efficiency Of Your Compressed Air System

A number of factors can hold back your air compressor from performing optimally and giving you the best results at lower costs. Whether it is your compressed air filter or lubrication, everything must work seamlessly in tandem, enabling you to make the most of your compressor at limited energy inputs.

Here are 8 ways in which you can boost the efficiency of your Elgi air compressors and ensure they work for you.

Understand Lubrication

Like all other equipment in your facility, an air compressor consists of moving parts. To avoid wear and tear on these parts while they’re in action, lubrication is a must! However, both over and under-lubrication can create problems. Also, the quality of the lubricant must be chosen carefully to avoid damage to the machine. This is all the more important if you’re using your compressor in a sensitive line of work such as food processing or confectionery, as it can poison the consumables. Each system requires a specific type or level of lubrication and the safest way out is to go through the user manual and follow the instructions.

Know how Particulates Impact your System

Particulates can enter your Elgi compressor system, hamper its performance or even cause damage to the parts. All of this depends upon the atmosphere where an air compressor is being used and accordingly necessitates the use of a good quality compressed air filter, such as an Elgi air filter.

Prevent Compressor Contamination

Both moisture and particulate matter can be a source of contamination for air compressors. This can cause poor air quality of air being forced out from the compressor or damage to the internal parts of the compressor itself. To avoid this, regular inspection, the use of air dryers, or the right air filter for the compressor, is important.

Cooler Building Temperatures

Both increases and decreases in temperatures can cause the performance of an air compressor to plummet. This can be combated by regulating the temperature of your building using air conditioning, central heating, or natural ventilation.

Reusing the Energy you Create

Sustainable use of air compressors can be ensured by avoiding wastage and making the most of the energy released. Air compressors release a lot of heat as they function. So make sure you tap this heat and utilise it well for some or the other function, in your building.

Keep your System Clean

All mechanised equipment requires regular upkeep and maintenance to ensure optimum performance. Air compressors are no exception. Inspect and replace the compressed air filter frequently and clean the inner parts regularly to keep the system in its best shape.
Whether it is replacing your compressed air filter or scheduling an audit for your compressor system, we can keep a close watch on all your maintenance parameters. We are the leading Elgi air compressor dealers in the country, and pride ourselves on having a rich industry experience of 72 years. So get in touch with VEMC –– the most reliable Elgi compressor dealer in Mumbai out there, and book an audit at 022 43436655 or email us at marketing@vemc.co.in.

When To Add An Air Dryer To Your Compressed Air System

by vemcoblogs -
Air Dryer in Compressed Air System
Air Dryer

If you own an air compressor, you must have come across lots of suggestions online or otherwise, of adding an air dryer to it. This is because moisture in compressed air can be quite harmful to your machinery and some moisture-sensitive business operations as well. The degree of harm of course varies from one business operation to another. It can cause moulds or rust to develop over the metallic parts of your equipment (including the air compressor itself) and significantly reduce their working life and also affect their performance. Well, this is where an air dryer comes in!

An air dryer effectively saps the moisture from the compressed air, helps you prolong the life of your machinery, and also performs the tasks at hand perfectly well. In this blog, we take you through all that you need to know about air dryers in your compressed air system. 

What type of air dryer do you need?

Your choice of an air dryer for your compressor depends largely on the function you want it to perform and also your geographic location. Your Elgi compressor dealer in Mumbai will typically take you through the two types of air dryers that use these mechanisms: 

  • Desiccant air dryers: These are best suited for typically cold climes where the risks of freezing are quite high. These air dryers use desiccants such as silica gel or activated alumina which suck the moisture from the air as it passes through the compressor system. These can also be put to effective use in cold storage of pharmaceutical or food processing companies.
  • Refrigerated air dryers: In this type of air dryer, a refrigerant chills the air down to sub-zero temperatures. This freezes any moisture present in the air which is then removed before rewarming the air and pushing it through the piping to finally use it for the operation.

Selecting the right air dryer for your application

Moisture can cause serious damage to your equipment and in fact your air compressor system. But besides that, some business or industrial operations may require absolutely moisture-free operation and atmosphere. According to one estimate, moisture-related damages lead to the discarding of approximately 10% of all containerized goods. For instance, moisture can be a cause of serious losses in confectioneries, dry fruit, or wafer packaging operations. If you’re using a compressor in such facilities, therefore, you must ensure the complete removal of moisture from the compressed air.  Most air compressor dealers will recommend an Elgi air dryer –– a fantastic product that can come to your rescue when it comes to getting rid of unwanted moisture in your compressed air.
Make sure you’re purchasing an Elgi compressor or Elgi air dryer, only from authorised Elgi air compressor dealers who have both the product and the technical expertise for servicing it. VEMC is one highly acclaimed Elgi dealer that deals in both Elgi air dryers as well as Elgi air compressors and has a rich industry experience of over 72 years. If you need help finding the right compressed air dryer for your requirement, feel free to speak to our experts at 022 43436655 or email us at marketing@vemc.co.in.

Industrial Air Compressor Preventative Maintenance

by vemcoblogs -
Air Compressor Maintenance

Maintenance of equipment is necessary to ensure longevity and energy efficiency. This applies to air compressors that are used daily in an industrial setting. In this blog, we take you through some of the pressing issues with regard to the preventative maintenance of your industrial compressors.

Difference between preventative and standard air compressor maintenance

In an industrial setting, it is necessary to have an inspection regime in place to make sure your compressor and its allied equipment are functioning at the optimum level. This set of checklists or procedures is known as standard maintenance. 

Preventative maintenance on the other hand is all about finding and arresting mechanical issues before they spread and cause costly downtime. The schedule of preventative maintenance varies from component to component. While some may require daily inspections, others can be checked once or twice a year.

Benefits of preventative maintenance for industrial air compressors

  1. Avoids downtime: Downtime for any production facility can be costly for business and with preventative maintenance, this can be avoided to a great extent.
  2. Saves costs: Sudden breakdown of systems can cost more as compared to regular preventive checks.
  3. Ensures energy efficiency: Preventative maintenance brings to the surface any gaps or issues behind the sub-optimal level performance of the air compressor.
  4. Increases longevity: With regular check-ups, fine-tuning, and cleanups, an air compressor system can be kept in good health. This helps avoid fatal faults or wear and tear in the system and increases its life span.

Recommended preventative maintenance checks

  1. Oil filter: Oil must not be allowed to leave with the compressed air as it can corrupt the surface if the compressor is being used for spray painting. Oil filters must be checked weekly and replaced after every 4000-8000 hours of use. 
  1. Lubrication: Change the lubricant every 3 to 6 months to ensure the health of the compressor. Non-lubricated surfaces of the system could cause serious corrosion of moving parts.
  2. Air filter: Check, clean, and replace the air filter regularly. You do not want unclean air or air laden with particulates to come out of the compressor and hit a surface being spray-painted or cleaned with the compressor.
  3. Motor bearings: Make sure the bearings are sufficiently lubricated. Carry out regular inspections and check the bearings after every 4000 hours. Lack of lubrication can cause the bearings to get stuck in place.
  4. Intake vents: The air entering the vents can become dirty if the intake vents are lined with dirt, dust, and grime. The same air will then be released in compressed form.
  5. Belts: Belts must remain firm to ensure the proper functioning of the pulleys and connected parts. Replace the belts before they lose their tension or break down in the middle of a task.

Which maintenance checks should a technician perform

While some maintenance tasks can be performed in-house by your own team, for others, it is best you consult the compressor technicians. Some of these situations are

  • Replacement of motor
  • Relocation of heavy compressors
  • Safety shutdown instructions
  • In case of a mechanical breakdown

How to Use an Air Compressor: Things to Consider

by vemcoblogs -
How to Use an Air Compressor

A number of things need to be considered while using an air compressor for your operations. These include maintaining the right parameters like pressure, checking oil levels, having safety measures in place, etc. In this blog, we take you through all these aspects in detail.

Picking the right compressor for your needs

For domestic purposes, the most commonly used air compressor is the reciprocating piston type. This works by reducing the space to increase the pressure of the air inside the compressor. This is quite similar to the working of an internal combustion engine. 

For industrial purposes such as large refrigeration or pneumatic tools, rotary screw air compressors are mostly used. These work by compressing the air inside in a continuous sweeping motion, thus avoiding any pulsations that may occur in a reciprocating piston-type compressor. 

Getting started

  • Place your compressor in the right position. Ensure that the compressor is on an even and stable surface and the power source is always grounded. 
  • Turn the power on and allow your compressor to run for a minute. 
  • Set the psi as per your requirements. Adjust the pressure till you reach the recommended pressure for a particular tool. 
  • Connect the air hose and the tool you’re going to be working with. 

Oil and air intake

  • Check the level of oil in your compressor. Add oil by removing the cap and filling up to the mark if required.
  • Check the drain valve located at the bottom of the air tank. Make sure it is tightly closed.

Moisture and drainage

It is necessary to remove excess moisture from your air compressor at frequent intervals. This is usually done through the drain valve present at the bottom of the air tank. Wrench open the valve, allow the condensed moisture to flow out, and replace the valve. Always store the air compressor in a cabinet away from moisture.

Power

Make sure you turn off the compressor’s switch before you plug it into a three-pronged socket. As much as possible, avoid using extension cords if you’re unable to reach the spot of operations comfortably. Instead use an additional air hose and plug it into the first one. Extension cords can cause overheating of the air compressor. 

Meeting all safety regulations

  • Always use polycarbonate goggles and closed-toe shoes while operating the air compressor. 
  • Pull on the safety valve to test if it works.
  • Ensure you are only applying the right amount of pressure for a particular operation and as per the requirements of a particular tool. Try to maintain the pressure on a slightly lower side for safety.
  • Only operate the tool while there is air in the tank.

What is The Difference Between PSI and CFM in an Air Compressor?

by vemcoblogs -

If you’re looking for the right air compressor for your business, and are researching on the specifications of the product, you must have come across acronyms like PSI and CFM. These are necessary to tell you which size of air compressors are fit for your needs. Both these parameters are performance indicators of air compressors and other air-powered equipment. The main difference between PSI and CFM is that the former measures pressure and the volume of the latter measure. In this blog, we take you through a detailed understanding of both these metrics.

What is PSI?

PSI stands for pounds per square inch. Quite clearly it measures how many pounds of air occupies a square inch area. The greater the PSI value of a compressor, the greater pressure it is exerting and hence the more powerful it is considered to be. Quite simply, an air compressor with a PSI reading of 120 would indicate that it delivers 120 pounds of pressure per square inch. On an industrial compressor, the PSI value is typically displayed within the compressor system. As a convention ‘PSI’ is written in small letters. 

What is CFM?

CFM stands for cubic feet per minute. This indicates the volume or output rate of the air compressor in terms of cubic feet of air per minute. Simply put, it indicates how much air is being moved per minute. CFM is always measured at a particular PSI and increases proportionately along with the horsepower applied. Domestic compressors typically offer a volume of around 2 CFM while large industrial compressors that usually run at 200 HP, can deliver up to 1000 CFM of airflow. 

How are pressure and flow related in an air compressor?

To run an air compressor optimally, both volume and pressure must be sufficient. The principle isn’t very different from that of a garden pipe. When you squeeze the end of the pipe with your thumb, you are in effect reducing the space and creating less room for it to flow out. This will make the water shoot out farther. In air compressors, PSI and CFM relate to each other in a similar way. 

For the purpose of mathematical calculations, the relationship of pressure with volume in a compressed system can be demonstrated by Boyle’s law which states that:

P1 x V1 = P2 x V2

(P1 and V1 represent initial pressure and volume, and P2 and V2 represent final pressure and volume.)

The risks of over-pressurisation

Many times, users may over-pressurise the air compressors to ensure enough pressure is applied for a given task. This could pile up irrecoverable costs of energy losses since an increase in PSI value invariably increases the energy consumed. It can also reduce the lifespan of your equipment as the ‘artificial demand’ (another term for over-pressurisation) can cause unnecessary wear and tear.

3 Must-Have Compressed Air System Accessories That Improve Performance

by vemcoblogs -

Have you ever observed your air compressor functioning closely? Their entire efficiency depends on receiving the right proportion of clean and dry air, at the right locations and at the right pressure. When your compressor system is not working properly, it means that at least one or two of its components are malfunctioning — perhaps a blocked filter, lack of an air dryer, or an unsuitable pressure regulator. 

It’s commonly said that your air compressor system is as powerful as its weakest component. Hence, it’s extremely important to ensure that your compressor has all the right accessories it needs to function properly. They not only help boost your energy efficiency, but also reduce frequent needs for maintenance. The ultimate benefit is the long life of your compressors. 

In this blog, we list out 3 of the most important accessories you need to keep your air compressors healthy and running: 

1. Compressed Air Regulator – Air compressors run on extensive amounts of energy, with requirements varying for different applications. So, when the energy input goes wrong, it can damage the components in the system. It also means wasted energy and ultimately, wasteful expenditure. 

Choosing the right pressure helps you zero in on the right energy requirement for your compressor. If your compressor runs at a higher pressure than is required, you may be wasting energy, while adding unnecessary pressure on the other parts such as hoses and fittings. This will lead to wear and tear and reduce the lifespan of your compressor. If a component is best suited to work at 100 psi and you operate it at 150 psi, it will not perform optimally.

Regulators help solve this problem by regulating pressure from the machine and aligning it with specific components based on different pressure requirements. 

2. High-performing Filter – Your compressor systems don’t necessarily have clean air inside them. They may contain several particles, aerosols, and vapours often found in the natural environment. 

A powerful filter can help remove contaminants from the compressed air and hence, it’s important to choose the right filter. For some applications, specialized oil-removing filters will make more sense; for others, dust and pre-filters may be apt. Before zeroing in on a filter, be sure of the requirements. 

Most choices usually boil down to coalescing filters, vapour removal filters, and dry particulate filters. 

3. Air Dryer – It’s natural for compressors to create lots of vapour while it is operating. This stagnant moisture can damage compressors and their parts. Especially in the case of metal or machinery, the presence of moisture leads to mould growth. This is not an ideal condition for any application, particularly in hospitality or healthcare. Blocked air pipes, stuck air cylinders, and rusted transmitters can also lead to increased maintenance and repair costs. 

Air dryers can help eliminate moisture before they reach the tip of the tool. Air dryers such as desiccant dryers use silica gel, activated alumina, or molecular sieves to de-vapourise air. You can choose from the desiccant and refrigerated dryers for your compressor systems. 

Getting the Right Parts

Your compressor system is heavily dependent on tools and accessories. Hence, the right tools are critical for compressors to function efficiently. Even if you are using a good air compressor, you may not get the desired performance if the quality of the parts is sub-par.

Debunking myths about compressed air systems

by vemcoblogs -

A lot misperceptions continue to prevail around the functioning of air compressor systems. Whether it is about their safety or the tasks that can or cannot be accomplished with them, myths around their use galore!

In this blog we debunk 7 of these major myths.

Myth #1: Compressed air can be used for cleaning dust and dirt from work spaces.

There is a fundamental difference between your domestic vacuum cleaner and an air compressor. The former sucks in air while the latter pushes compressed air with great pressure and speed. Quite clearly therefore, using compressed air for cleaning an office space will only result in dispersing the dust or waste particles wider across the floor, rather than being sucked in and vanishing into the compressor system.

A pneumatic tool operated using air compressors could in fact accelerate the debris particles and shoot them into people’s eyes causing severe injuries. Besides the particles could also land in vents, outlets and machinery causing blockage or damage.

Myth #2: To make the best of part–load performance, the most optimal solution is a variable–speed drive.

While it may make for a great sales pitch, air compressors cannot really be adjusted to suit different operations simply by changing their speed.Variable-speed air compressors are not really helpful across a wide range of applications.

Myth #3: Oil carryover is accelerated in variable speed drives.

In reality, speed drive has no impact on the rate of oil carryover. It is only aided by two factors, that is, heat and low pressure. In fact, lowering the air flow makes things more efficient by reducing the speed in the separator.

Myth #4: Flow controllers are unnecessary on air compressors with variable–speed drives.

Flow controllers enable most systems to offer their best possible performance simply by providing greater stability and pressure consistency. Flow controllers can even be beneficial in systems with VSD’s as they can help optimise their performance.

Myth #5: Synthetic air compressor fluids are all identical.

None of the synthetic air compressors are made of a hydrocarbon base. However, that’s where their commonality ends. These fluids otherwise vary drastically in terms of how they impact the performance of the compressors. Air compressor fluids are usually made of the PAO and PAG base stocks and each could have a unique effect on an air compressor system.

Myth #6: Aftermarket replacement parts are just as good as original parts sold by the manufacturer.

Original manufacturers design replacement parts keeping in mind the nuances of design and performance of your system. On the other hand, buying generic parts from an aftermarket manufacturer could impact efficiency, longevity and safety of the system. It is highly recommended to buy replacement parts from the original manufacturer only.

Myth #7: Compressed air is generally impure.

As opposed to common perception, compressed air is highly clean. In case there are any impurities, these exist due to poor maintenance, dirt in the ambient air or dirty system tubes and tanks.

5 Benefits of Regularly Changing Compressed Air Filter Elements

by vemcoblogs -

The enormous amount of focused energy that compressed air is able to produce is used for a wide-ranging set of activities. These include drilling, combustion, metalwork, filtration, chemical processing and moulding. While performing these operations, plenty of dust and particulate matter could get stuck in the compressor. In the short run, this impacts the performance of the compressor, while over the longer horizon, it could even affect its longevity due to wear and tear, or over-exertion. Air filters are therefore necessary to maintain the health and performance of your compressor.

Why air filter elements must be changed regularly

A compressed air filter typically has a coalescing filter, a dry particulate matter element or both. The former is used to pull and cohere water droplets or oil from the air while the latter helps trap dry particulates and microbes. Both use removable filter element. This is because in a typical industrial setup, these filters are under serious strains due to pressure and temperature fluctuations, corrosive chemicals, varying air speeds, extreme humidity etc. These require a change at regular intervals.

Let’s understand in detail the 5 benefits that arise from regular replacement of air filter elements:

1. Safety

By regularly changing your air filter, you’re committing yourself to particulate-free air on the factory floor. This will protect your employees from exposure to dust particles and microbes, where air compressors are being used for air conditioning. Besides this will also prevent accidents from unwanted overheating or system malfunction.

2. Cost control

By replacing the air filters regularly, you are reducing the risks of sudden breakdown and also the costs associated with it, such as downtime and expensive repairs. A saturated air compressor which doesn’t have a fresh air filter has to work harder causing more wear and tear, and also consuming more energy.

3. Efficiency

By enabling easy flow of air through your compressor, fresh air filter elements are highly useful in ensuring greater efficiency and productivity in your facility. The adsorption dryer beds for instance can work with maximum efficiency when new filters are used.

4. Boosting longevity

Filters are generally manufactured using borosilicate glass. If air filters are not replaced regularly, this glass can develop tiny holes causing accelerated contaminant flow. Overall, the regular replacement of air filters can help in ensuring longevity of the compressor system as it helps avoid the mechanical wear and tear, damages and corrosive glitches.

5. Reassurance

Having regularly replaced air filters can give you and your employees a sense of reassurance that the environment of the factory floor is safe, and the air is healthy to breathe. There are also lesser chances of breakdown and downtime, which could be a cause of serious business loss.

Piston Vs. Rotary Screw Air Compressors: Which One to Choose?

by vemcoblogs -

Air compressors have diverse applications for a wide range of businesses. Two of the most popular and widely used compressors are piston and rotary screw compressors.

Piston, also known as reciprocating compressors, find maximum use in the automotive service industry such as gas stations, tire stores, and general service shops, due to their price and availability. However, rotary screw compressors can be a suitable alternative as they offer better performance and require less space.

In this blog, we will understand the various points of difference between the two to help you choose the right one for your business.

Duty Cycle and Flow

Duty cycle is the time (calculated in percentage) a compressor can operate for, without getting overheated or causing wear. The allowable duty cycle for most piston compressors is 60-70%. Most piston compressors are oversized to allow space for the compressor to shut down and cool off due to the high temperatures. This may cause capacity problems during peak operating hours.

Modern rotary screw compressors, on the other hand, have in-built aftercoolers with huge surface area and robust fans to bring down the air temperature leaving the compressor.

Oil Carry-over

When pistons, cylinders, valves, and rings experience wear and tear, the quantity of air goes down. This causes more lubricating oil to seep through the piping into the usable parts. This is known as carry-over.

Piston compressors usually pass more oil than rotary screw compressors. Rotary screw compressors experience lesser oil seepage in comparison because the rotors don’t come in contact with each other and hence, don’t wear. Moreover, the compressor fluid also acts as non-wearing sealant that’s captured, filtered, cooled, and recirculated.

Energy Efficiency

For service industries that use compressors as large as 30 hp, energy efficiency becomes an essential factor to save electricity costs.

Piston compressors usually deliver 3-4 cfm per hp whereas rotary compressors deliver 4-5 cfm per hp. This shows that rotary compressors deliver more air per unit of input energy.

Maintenance

The maintenance of piston compressors is more expensive than screw compressors because the frequency of maintenance and the number of spares is significantly higher for piston compressors. However, the advantage is that any semi-skilled technician or worker will be able to perform the maintenance service.

Noise Levels and Vibration

Traditional piston compressors produce a lot of noise and vibration. As a result, they are mostly placed in separate rooms or outside. However, the immediate ecosystem directly affects a compressor. For example, a hot and humid room will increase the compressor temperature, reduce its shelf life and make it difficult to remove moisture and oil from compressed air.

Rotary compressors cause lesser noise and vibration. They also don’t need to be kept in separate rooms or sealed to the floor, offering more flexibility with their location i.e., well-ventilated areas.

A Short Guide to Moisture Control in Air Compressor Systems

by vemcoblogs -

It’s not uncommon for moisture and condensation to accumulate in your compressed air systems. Hence, you need a solution that can help prevent excess condensation in your compressor, especially if you’re in an industry that demands 100% moisture-free condensed air.

Why does your air compressor contain moisture?

Moisture is a natural by-product of the compression process. It just extracts the moisture that already exists in the ambient air.

Some of the common causes of moisture build-up in compressors are:

  • Equipment damage – When the internal parts of compressors wear out, it leads to moisture build-up. This causes the machine to lose its power to extract air as well as heat up, leading to more moisture build-up.
  • Environmental factors – Humid conditions also cause the machine to take in more moisture leading to more condensation.
  • Pressure on the compressor – When your compressor is strained beyond capacity, it gets heated up further more. This is especially the case with piston compressors, which heat up more when used for longer periods of time.

Why is excess moisture harmful?

Excess moisture hampers the workings of your air compressor. Some of the consequences of excess moisture are:

  • Rust and corrosion – Build-up of water in your compressors can lead to rust in and corrosion of the machine and pipes.
  • Damage to pneumatic controls – The machines that rely on pneumatic controls suffer from severe damage when there is moisture build-up inside them. That can result in rust and scale build-up.
  • Rapid wear and tear of production equipment – Moisture can cause the lubrication inside compressors to wash away. This causes metal components to wear away faster.
  • Damaged circuits and in-line filters – In-line filters help clean particles and oil from your compressor. Moisture increases pressure in the machine and reduces the filter’s efficiency.
  • Contamination – Moisture can damage end products, valves, and motors. It can easily contaminate solvents, lubricants, and food products.

How to eliminate excess moisture from your compressor?

Some of the solutions you can try out to remove moisture build-up from your compressors are:

  • Install an air dryer – An air dryer works in tandem with an air compressor to remove moisture. There are four common types of air dryers: refrigerated dryers, desiccant dryers, membrane dryers, and deliquescent dryers.
  • Get a piping system – Piping systems are one of the most cost-efficient systems. In these setups, the metal pipes absorb heat to bring down the air temperature, and can be a good solution for office buildings.

6 Air Compressor Maintenance Tips to Avoid Breakdown

by vemcoblogs -

Air compressors of all makes and models require varying degrees of maintenance. Whatever the model or quantity of compressors you use for your operations, it’s essential to regularly inspect the parts and service them, whenever necessary. Failure to perform routine maintenance on your compressors can lead to early failure or expensive repairs.

Here’s a short guide on how to keep your air compressors running at full capacity:

1. Drain your air receiver tank

Use the drain and plug at the bottom of the compressor to drain the air from the compressor’s air receiver tank. Collection of air in the machine leads to the accumulation of water and moisture while the machine is running, especially during summer, when humidity is higher. The moisture gets collected in the receiver tank and if not drained regularly, it can lead to corrosion of the receiver tank and piping. An automatic and a manual bypass drain during daily inspections is ideal.

2. Inspect the hoses

Hoses are often the most vulnerable parts of compressors because they need to be strong enough to transfer air between the machine and the final point, which can put a lot of strain on them. Checking your hoses on a weekly basis is extremely important. Cold weather also affects hoses — it causes them to crack or corrode and hence leak. Routine checks are ideal for keeping the hoses clean and leak detection devices are ideal to find the leaks.

3. Alter the air filter

Air filters usually trap a lot of junk. The filters are designed to bear a heavy load, without which, a lot of impurities will accumulate and degrade the performance of the compressor. This contamination is critical for industries such as food and beverage, hospitals, and labs. Air filter inspections should be done regularly, especially in dusty conditions.

4. Clean the intake valves

The intake valves of an air compressor must be clean to function fully. When compressors are put to constant use, dust particles and other elements get sucked into the vents. Cleaning the vents at least once every three months is essential.

5. Change the oil

The compressors that run on oil need the oil to be changed regularly as well. Fresh oil helps run the various parts of the engine smoothly. Especially in humid conditions, the oil loses its viscosity and fails to lubricate the different parts.

6. Get it inspected by a professional service team

Allowing a professional service team to regularly check leaks and perform preventive maintenance and required repairs, can offer a lot of peace of mind. Scheduling this regular maintenance can help save time and money in unnecessary breakdown repairs.
