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

What Size of Industrial Air Compressor do I Need?

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.

How To Improve The Compressor Efficiency

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 to Watch in 2023

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

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.

When To Add An Air Dryer To Your Compressed Air System

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

Industrial Air Compressor Preventative Maintenance

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

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.


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?

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.
