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.

Keeping your air compressors healthy and functioning smoothly is essential and possible through regular maintenance.

What type of piping is needed for my compressed air system?

by vemcoblogs -

Compressed air systems find use in various industries such as construction, automotive, metal-work, and wood-work. Tools used in these industries require compressed air to run and since they don’t need motors, they are lightweight and handy to use.

Compressed air systems work best when air is released from the system at the right pressure, volume, and consistency. These systems can run the risk of miscalibration which robs them of their power and leads to rust and debris build-up in the pipes.

This makes choosing the right air compression system as well as its parts integral to their efficient functioning. Pipes are one of the most critical components in a compressed air system and defective and inefficient pipes can often lead to loss of power. Moreover, obstructions and blockages, moisture build-up, and sharp angles can also affect the pressure of compressed air systems negatively.

Paying proper attention to the size, layout, installation, and maintenance of pipes used in compressed air systems is a prerequisite to ensuring their powerful performance. Two materials usually go into making pipes: plastic and metal. Of these two, metal pipes are the preferred choice for compressed air systems.

Here are some of the common types of metal pipes used for compressed air systems along with things to consider when choosing them:

  • Black steel pipes are the most commonly used ones because they are strong and durable. However, it can be time-consuming to install them and they are also susceptible to corrosion. There’s also the risk of the threaded connections slipping and leaking.
  • Another widely used type is galvanised steel pipe. They help solve the corrosion problem. However, in some cases, the galvanised coating can come off and cause blockages in the air flow.
  • Copper pipes come with a lot of advantages. They are free from corrosion from condensation and are easy to cut and weld. They are lightweight and come with a wide range of fittings to choose from. Their smooth interior means that they can sustain solid laminar flow. However, they can be a bit expensive since they require time and skill to install, especially the threading and soldering bit.
  • Aluminium pipes can also be a good choice since they are lightweight, durable, and anti-corrosive. They’re also easy to install and maintain than other types. The only downside is that it can be as expensive as copper.
  • Stainless steel pipes are corrosion-free, both from the inside and outside. Moreover, they are easy to weld and press. However, they can be heavy and the material cost can be on the higher side.

How often should I change the oil in my pump/piston?

by vemcoblogs -
How often should I change the oil in my pump/piston?

Air compressors need to be in optimum condition to give the best performance. Maintaining them properly ensures that they last long and help save money in the long run. There are several maintenance routines to consider for a smooth-functioning air compressor. One of the most important routines is changing the oil in the pump or piston of the air compressor. While focusing on other maintenance routines, many people overlook this one, which often leads to poor performance of the air compressors and, in some cases, also causes damage to the systems.

Why is it important to change the oil?

The oil in a compressor has several functions apart from lubrication. It helps the compressor parts to cool down so that the motor doesn’t overheat. The oil also acts as a sealing agent during the compression process.

If the compressor doesn’t have enough oil, it may not perform as efficiently as it’s supposed to. Low oil levels cause the compressor to overheat since air compression produces heat and oil absorbs the heat. Moreover, low oil levels also increase friction, which can lead the compressor to overheat. It’s also important to replace the contaminated oil from the air compressor regularly. Failing to replace the old oil with new oil causes debris and particles to build up and hampers its smooth functioning. Lack of sufficient oil can also increase the chances of rust, wear and tear, and corrosion. Finally, oil has a tendency to oxidise in the presence of water and heat. This reduces its effectiveness which can lead to costly breakdowns.

In some systems, overheating leads to an automatic shutdown. In such situations, the compressor can be used again only after it has cooled down and the oil has been replaced.

How often should the oil in an air compressor be changed?

Air compressors need consistent lubrication to prevent friction on the pumps or pistons and hence, the oil level must be checked regularly. The frequency of changing oil in compressors depends on the type of compressors used. Some compressors need more frequent changes than others and it’s best to consult the user manual that comes with the system. It’s possible to even find the life expectancy of some oils in terms of service hours in some of the manuals.

For rotary screw compressors, the oil should ideally be changed every 2000 hours or 12 months, whichever is earlier. For reciprocating air compressors, the oil needs to be changed every 3 months.

Performing an oil analysis that checks for important factors such as viscosity, particle count, water contamination, and total acid number (TAN) can help determine when to change the oil. It’s ideal to conduct an oil analysis every 500 to 2000 hours, depending on the user manual and the warranty.

What are the Basic Reciprocating Compressor Components?

by vemcoblogs -

A reciprocating compressor or piston compressor uses pistons that are aided by a crankshaft. The main function of the reciprocating compressor is to increase the level of pressure in gases.

A reciprocating compressor has several components that aid in the passage and compression of the gas. Each of these components plays a specific role and is equally necessary for the smooth functioning of the reciprocator compressor. 

Let’s take a closer look at the basic components of a reciprocating compressor:

Frame

The frame or crankcase is a sturdy structure that encloses all the rotating components. ELGI air compressor frames are square or rectangular shaped. In Integral Compressors, the frame is fitted to both the compressor and engine-powered cylinders which are driven by one crankshaft. 

Cylinders

Cylinders play a crucial role in containing the air that needs to be pressured. A compressor could have either large low-pressure cast iron cylinders or small high-pressure steel compressors. Cylinders help to keep the reciprocating compressor cool during the compression cycle. Reciprocating compressor dealers might also show you cylinders with replaceable liners that can be changed when damaged or worn out.

Distance piece

The distance piece is an intermediary component that attaches the low-pressure cylinders to the frame of the compressor. Due to the distance piece in ELGI air compressors, the cylinders can be detached if required. A distance piece could have a single, double or extra-long compartment arrangement. 

Piston

The piston is what compresses the gas within the cylinder. It is typically made up of a strong and heavy material that does not react with the gas in the chamber. You might find pistons made from aluminium or cast iron when looking for compressors at reciprocating compressor dealers.

Piston rings

Piston rings are placed around the piston. These rings could be either metallic-like bronze or non-metallic like a fluorocarbon compound. They are subject to friction as they come in contact with the inner walls of the cylinder and might wear out easily. Piston rings might have to be replaced regularly but help to protect the piston from damage due to friction. 

Cross head

The piston is inserted into the cylinder bore with the help of a cross head. Narrow pistons used with a cross head are more efficient as they can accomplish longer strokes. 

Crankshaft

This is what drives the piston. It is attached to the electric motor shaft on one end and to the piston on the other. Higher powered crankshafts are made of forged steel while those operating less than or equal to 150kW are made of ductile iron.

Connecting rod

The connecting rod connects the crankshaft to the piston and enables its upward and downward motion. The connecting rod is typically made of the same material as its corresponding crankshaft.

Valve

The valves of a reciprocating air compressor ensure that the gas flows in only one direction. On one side of the cylinder, there are inlet valves while on the other there are outlet valves. Valves are of three types:

  • Ring valve
  • Poppet valve
  • Plate valve

Bearings

Bearings complete the structure of the reciprocating compressor. They ensure the proper radial and axial positioning of components of the compressor including the crankshaft, connecting rod, and cross head.

If you are looking for reliable ELGI air compressor dealers make sure that you are first clear about the type of compressor you need for the job at hand.

Why My Air Compressor Is Losing Pressure?

by vemcoblogs -

Air is drawn in through the inlet valve, compressed to the necessary volume, and released through a discharge valve into a storage tank by air compressors. An electric motor typically powers the compression operation. When the system is using a much greater quantity of energy than before, pressure drops will be apparent. It is important to eliminate or reduce pressure drops wherever possible as this will improve the system’s efficiency and help reduce your maintenance costs.

You can reduce or eliminate the pressure drops in the following ways:

Examine Tubing

If your Elgi air compressor system has tubing, it is crucial to do so in order to ensure that the tubes are still airtight. Tubing issues might also be brought on by rust build-up. It’s time to replace the tubing if you notice any rust accumulation or cracks.

Improve the piping layout

Although it has been demonstrated that piping systems older than five years can leak up to 25% of their capacity, many institutions are sluggish to replace ageing machinery. The majority of institutions still employ galvanised iron, also known as “black iron,” for their Elgi compressed air pipe systems even when a more effective option is available.

Look for worn-out hoses

Air leaks could be caused by kinked or worn-out hoses. Regular hose inspections to ensure they’re in top functioning order may help you detect leaks earlier and prevent problems from getting worse. Verify that none of the hoses in your system are positioned so that they are under stress.

System connections should be taken into account. Each connecting piece needs to be accurate in size and tight. If any of your connection points are unnecessarily convoluted, it might be time to redesign your system with a more straightforward strategy in mind.

Check Regulators

The pressure regulators’ settings could be the source of the pressure drop and energy rise. You can try to reset it, but if the problem persists, it might need to be replaced.

Replace Lubricators

The lubricators on your air compressor must correspond to the system’s actual flow rate. They might need to be altered if they are not operating properly within the constraints of your system.

Filter upkeep or replacement

After leaks have been found and addressed, it’s crucial to take action to stop further breaches from developing. Leaks caused by dust, corrosion-causing moisture, and the accompanying pipe sludge reduce efficiency and raise the possibility of failure or end-product contamination. Regular system maintenance not only minimises risk but also stops new leaks from developing. The quality of compressed air is ensured, and pressure drops are avoided through routine filter changes.

Five Benefits Of Upgrading Your Air Compressor

by vemcoblogs -
Upgrade Your Air Compressor to Save Money and Energy

Industries of today are leaning towards initiatives that can reduce carbon footprint and are generally more sustainable for long term use. But when a business considers upgrading its air compressor system, it may be daunted by the initial costs. However, the benefits of upgrading can often far outweigh these. Let’s take a look at five advantages of making the move:

High return on investment

A major benefit of upgrading your air compressor is the resulting return on investment. Most often, the return on investment of upgrading is higher than the cost. This might be in the form of energy savings and other efficiency-increasing benefits.

Significant energy savings

Another huge advantage of upgrading your air compressor is the savings on energy that it yields. On average, the costs of electricity account for a whopping 80% of total costs. An up-to-date system runs much more efficiently than a worn down one and hence, leads to a significant reduction in electricity bills. This way, the upgraded system makes up for the initial cost rapidly.

Higher uptime and reliability

Air compressors, like most other systems, require maintenance from time to time. However, while maintenance takes place, the system will experience downtime. The higher the downtime, the more the possibility of losing revenue. Systems that are upgraded as needed face less downtime. Additionally, they have lower chances of breaking down and are much more reliable for regular operations, helping you to minimize production losses.

Avail of government incentives

Most governments including India’s Bureau of Energy Efficiency, have introduced initiatives to cut down the use of energy by energy-intensive industries. Called PAT Cycle VI, the Indian government offers incentives if your business adopts equipment that consumes less energy to operate. This also serves to increase your return on investment while reaping the benefits of this act.

Better health and safety for everyone at work

Upgraded air compressor systems also improve the environmental working conditions of your site. By drastically enhancing the quality of the air at work, your employees’ health and safety will be protected. As a result, they will fall sick much less than before, which means they will probably take fewer days off from work, thus increasing their productivity.

Overall, upgrading your air compressor is a step in the right direction. Consult an expert to review the health and status of your current system. If it needs an upgrade, you will now understand why getting it is a prudent decision.

What Type Of Oil Should You Put In Your Commercial Screw Compressor?

by vemcoblogs -

Just as parts of your car and other appliances need to be lubricated in order to perform properly, so does your air compressor. But how can you tell what kind of oil is suitable for your air compressor, particularly a commercial screw compressor? To understand this, let’s first take a look at the role of air compressor oil.

Air compressor oil is a lubricant that helps to reduce the early wear and tear of air compressors. It can either be synthetic or natural and varies in characteristics like makeup and viscosity. It is important to note that air compressor oil is different from motor oil. For one, the latter contains detergent and much more carbon and sulfur.

Apart from lubrication, the benefits of using air compressor oil are many:

1. Absorbs heat

The oil keeps the air compressor at a cooler temperature by soaking in the heat that is emitted.

2. Resisting oxidation

The additives present in air compressor oil help keep the oxidation and acid formation processes at bay.

3. Improves longevity

The additives in air compressor oil also play a role in lengthening its shelf life, keeping the components of the machine protected when in standby mode, and increasing the compatibility of the oil with various conditions.

4. Stands up to the cold

Air compressor oil remains viscous even in cool temperatures, unlike many other lubricants.

The two main types of air compressor oil are standard and synthetic

  1. The standard type of air compressor oil contains a mineral oil base. This makes it cheaper than synthetic and is advisable for light or medium-duty and those who need not use their compressors continuously.
  2. On the other hand, synthetic air compressor oil contains a heavily processed and refined synthetic base. As a professional who runs an air compressor more than thrice a week, this is a suitable option for you. What’s more, synthetic oil keeps the air compressor functioning smoothly and with little to no noise. It also does a good job of preventing it from overheating.

For commercial screw compressors, it is best to use synthetic oil. These do not contain additives or sulfur that can often produce an unwanted buildup on the valves. They are also consumed at a slower rate than the standard kind, help to prolong the life span of the compressor, and stay cooler during operations. What’s more, they create fewer deposits of sludge and carbon that can adversely affect the performance of the machine, and produce air discharge at lower temperatures than standard oil. Synthetic oil also makes for safer operating conditions as its ignition temperatures are much higher than standard oil.

Suffice to say, synthetic oil is the best choice to keep your commercial screw compressor performing optimally.

ELGi Air Lube Oil provides an effective solution to suit various applications and work environments. You can choose this carefully formulated oil as a reliable way to meet your needs in different operating conditions.

How a Differential Pressure Gauge Can Help to Maintain the Air Quality in a Compressed Air System

by vemcoblogs -
How a Differential Pressure Gauge Can Help to Maintain the Air Quality in a Compressed Air System

What is differential pressure?

Differential pressure (DP) refers to the difference between two applied points of pressure. When this value tends to fluctuate significantly in a process system, it can be an indication that the component is in need of repair, replacement or maintenance. This is why, it becomes important to understand how to read differential pressure to keep functioning at optimal levels without the equipment breaking down.

What is a differential pressure gauge?

A differential pressure gauge is an instrument that is used to measure the differential pressure in a system and display the results visually. It can monitor the status of the air filter, which is an integral part of most compressed air systems. While the air filter performs a key function in removing contaminants entering the system, it creates a resulting change in pressure between the entry and exit points of the system. With passing time, these points accumulate dirt and get clogged, thus increasing the differential pressure.

A differential pressure gauge can track the changes in differential pressure in the system and alert you when it has reached a point when the filter must be replaced. This is a major benefit in operating an air system, as it can help minimize downtime from a malfunctioning and conduct timely maintenance as and when required.

Here is a look at some important facts about using differential pressure gauges:

  • Although a differential pressure gauge is an indicator of air quality, it does not directly influence the quality of the air that goes out from the system. However, it checks the condition of the air filter in the system and plays a large role in keeping it healthy.
  • If you have a compressed air filter fitted with a differential pressure indicator or monitor, keep in mind that this differs from a true differential pressure guage. Such devices are not as accurate or calibrated as the latter.
  • Be careful not to fall into the trap of thinking that you must only change your compressed air system’s filter when there is an increase in the differential pressure. A marked fluctuation in differential pressure means that the air compressor has to function at higher pressures for prolonged periods of time to overcome the same. So, fluctuations can occur regardless of the condition of the air filter. Besides, any wear and tear in the filter can sometimes prevent the differential pressure from showing a change, despite being clogged up.

A differential pressure gauge is a valuable tool to monitor the condition of the air filter in a compressed air system, which is instrumental in ensuring that the system maintains high standards of air quality.

5 benefits of regularly changing compressed air filter elements

by vemcoblogs -
5 benefits of regularly changing compressed air filter elements

Compressed air is indispensable to a vast number of manufacturing and industrial applications including pneumatic tools, petrochemicals, and food processing, among others. Most compressor systems are fitted with a filtration system to optimize the movement of the air and minimize the risk of contamination. To keep the system functioning smoothly, it is necessary to conduct regular maintenance and replace the components that have become worn out. Parts of the air filtration system in the compressor have a limited shelf life and in order to keep working effectively, they must be checked and replaced periodically. Let’s take a look at five benefits that changing the compressor’s air filter elements regularly provides:

1. Maintain a high quality of compressed air

Changing the air filters regularly makes for a safer, cleaner work environment without the risk of undesirable contaminants that can cause damage to your staff and equipment. To keep the air filtration system unclogged and functioning at peak efficiency, you need to change the air filters as often as required. Check with the manufacturer to know what the recommended frequency of your filters is.

2. Protect adsorption dryer beds

In some systems, using fresh new filters enables the adsorption dryer beds to operate at their most efficient levels. With reduced particulate matter present in the airflow over these, they are going to remain healthy more easily and offer maximum advantage.

3. Decrease operational costs

Changing the air filter parts regularly cuts down on the risk of running into problems with the entire system which can result in downtime, costly repairs, and all-around inefficiency. Without proper maintenance of the air filtration system, the compressor has to work harder to deliver the required airflow. This puts a burden on the compressor and makes it consume more energy and be susceptible to damage and lowered durability.

4. More productivity and profitability

An outcome of conducting consistent maintenance and changing the air filters is that you will benefit from a boost in efficiency, thereby resulting in increased productivity as well as profitability for your business.

5. Sense of assurance

Changing the air filtration parts of your compressor system keeps everything operating much more smoothly than if you did not. It is a habit that gives you peace of mind and a sense of assurance that your system is running at the best of its ability in the safest way possible. It reduces the anxiety and inconvenience of unexpected downtime. This in itself is invaluable when it comes to the daily operation of your business or factory.

These benefits far outweigh the consequences of not changing the air filter parts regularly as required. So, keep them in mind when maintaining your air compressor system!

Understanding The Cost of Compressed Air

by vemcoblogs -

Compressed air is an indispensable part of most industries. Without it, entire sectors of production would be defunct! It is so essential that it is referred to as the ‘fourth utility,’ after electricity, water, and gas. However, there is a significant cost attached to it. In fact, about 10% of the electricity consumed industrially goes to generating and using compressed air.

Keeping industrial units supplied with compressed air costs a substantial amount of money. So, it would be prudent for businesses to focus on the consumption of energy, which makes up the majority of the cost of generating compressed air. Energy consumption costs are much higher than the initial cost of air compressors or their maintenance. A whopping 80% of the total cost of the compressed air system will be from the electricity it uses up. Because this is such a huge percentage, determining the cost of compressed air becomes important in order to minimize waste heat and electricity bills.

To identify the ways that you can save such costs, take a look at your business’s requirements of compressed air as well as the components of your compressed air system, along with all the associated costs. When you do this, make sure to account not just for your business’s current system, but also for the one you envision to be in place in the future. Plan for the longer-term demands rather than just the current ones.

Here’s an overview of the components in a compressed air system that you need to look at:

Air compressors

Aim to have an energy-efficient air compressor rather than one that just carries a lower price tag. As mentioned earlier, the initial cost is just a small fraction of the total cost.

Dryers and filters

Compressed air has contaminants that, depending on the application at hand, need to be filtered. There is an additional cost and equipment to this process, so be mindful of that.

Drains

Drains remove the collected condensate of the compressed air system as required.

Piping

A good piping system is crucial for smooth movement of the air and eliminates air restrictions, leakages, and pressure drops.

Ventilation

Ventilation is key to cutting down heat circulation to subsequently reduce energy consumption.

Air leakage

It is of paramount importance to detect and fix any air leaks because these can have a heavy cost otherwise. Monitor your air compressor constantly to prevent this from occurring.

Central controller

In systems that consist of more than one air compressor, a central controller may play a big part. It can decrease the average pressure band (a pressure reduction by one bar reduces energy usage by 7%), regulate the compressor speed, and control compressor capacity.

A streamlined air compressor system strategy can help you reduce your operational costs significantly, so plan ahead and reap the benefits!

Here’s What You Need to Know About ISO Classes for Compressed Air Quality

by vemcoblogs -
What You Need to Know About ISO Classes for Compressed Air Quality

We’ve heard the term “ISO standards” quite frequently. But what exactly are they, and why are they so important? Let’s take a look at the concept. The International Standards Organisation (ISO) is a non-governmental body made up of a network of institutes from 159 different countries. ISO is the world’s largest developer and publisher of international standards and is accepted universally.

Compressed air is an indispensable utility that is used widely across different industries. But, compressed air is not all of uniform quality. Some uses, such as pharmaceutical production and food handling, call for impeccable quality and cleanliness of the air. In other cases, the primary objective may be to ensure the lifetime and reliability of industrial tools that are powered by air. The ISO standards play a key role in determining the level of air purity required for your particular application. Meeting ISO standards is also important in maintaining and protecting the quality of your production. In some cases, not complying with them can lead to heavy penalties or even your production facility being shut down!

The ISO 8573 air quality standards and ISO 12500 compressed air filter standards help lay a sound foundation for selecting the right air treatment products. ISO8573 is the compressed air quality standard and comprises nine separate parts — part 1 for quality requirements of the compressed air, and parts 2 to 9 for the methods of testing for a range of contaminants.

Compressed air contains contaminants like moisture and pollutants, and must be filtered according to the application’s requirements. Usually, the purer the air must be, the more costly it is to produce. This is why it is crucial to choose the right levels of air purity in order to reduce costs and benefit the environment.

The ISO 8573-1:2010 is a useful tool that makes the task of choosing the right air purity for your application that much easier. It ranks the acceptable levels of different types of contaminants as classes.

The ISO 8573-1:2010 standard is divided into three groups of contaminants—solid particles, water (including liquid and vapor), and oil. Each of these categories is further classified into ten different purity classes — eight for particulates, ten for water, and five for oil. The lower the assigned number to a category, the higher the air purity requirement for it. For example, class 5 would require far less air purity than class 1.

Now that you know how to match the ISO class to the compressed air quality required, how will you select a filter? The answer is simple — just find the particular ISO class on the filter. Once you identify the ISO class for your particular task, planning the equipment you would need becomes much easier.

Five Mistakes Not to Make When Choosing an Industrial Air Compressor

by vemcoblogs -

Choosing an industrial air compressor for a specific application is an important task. It is a seminal step, and although it can be complex, it is crucial to get right for smooth operations. Here are five mistakes that are necessary to refrain from making when selecting an air compressor:

Choosing the wrong compressor technology

There are several different compressor technologies in the market including centrifugal, screw, piston, and scroll compressors, and making the right choice best can be confusing. Here’s a guide to help you select the one that fits your requirements best.

  • Piston compressors are ideal to operate in a relatively smaller space where the daily hours of running are low and duty cycles are shorter. If you are looking for a compressor in these conditions that comes with an affordable initial cost, this may be the right compressor for you.
  • Screw air compressors are highly energy-efficient, make less noise, and are easier to maintain. If your tasks are going to need long duty cycles, and the number of hours of running each day will be higher, these can be suitable for you.
  • Scroll air compressors make minimal noise and maintain a fully oil-free environment. They are appropriate for use in places like hospitals and universities.

Picking the wrong compressor size

Selecting the right size for the compressor is crucial for efficient operations. It helps to know the exact measures of operating pressure and the flow of volume in the air compressor for your processes. This will then help you determine the correct size that you need the air compressor to be.

Ignoring your air quality requirements

The application of the air compressor may have a standard air quality requirement. For example, in pharmaceuticals, you may need the air quality to be completely oil-free, while in other industries, the rules may not be as stringent, such as in manufacturing. You can consult an air compressor expert for help with identifying yours.

Not considering the lifecycle costs of the compressor

When choosing an air compressor, bear in mind that a majority of its lifecycle costs are due to energy consumption. This is why it is important to choose a machine that is energy efficient for use in the longer term. Don’t make the mistake of underestimating the total lifecycle cost of the air compressor.

Going with the wrong service provider

Choosing the right compressed air service provider is as important as choosing the right air compressor machine. Make sure to go with a reputed provider that not only supplies OEM parts but also offers quality maintenance and emergency support.

Follow the above tips and avoid costly mistakes when selecting an air compressor!

How To Achieve Efficiency, Performance, And Quality Compressed Air Strategy

by vemcoblogs -

Compressed air is a common source of energy that is used across several industries, including manufacturing. Compressed air can also prove to be quite expensive, often consuming more energy than most equipment in a manufacturing plant. The good news is that compressed air systems can be greatly improved in efficiency, performance, and quality with the right strategy. 

There are three main components of the air compression system that influences performance, efficiency and quality. Let’s take a look at them.

Composition of the air intake

Clean air intake by the system allows the compressed air to move smoothly through it. Contaminated air is impure, so a build-up of it over time leads to wear and tear, and makes the storage capacity suffer.

Temperature of the air intake

The cooler the air, the less energy is required to compress it. The temperature of the intake air determines its density.

Humidity

Moisture can harm the air compression system if it collects inside because it causes the parts to rust. It can also catalyse wear and tear, and leaks while reducing the storage capacity. Making sure the air is dry will more likely prevent such damage to the system.

You can also optimize the design of the air compression system to increase its efficiency. There are three ways to do this:

Cooldown intake air

Since the energy required to compress cool air is less than that for warmer air, you can move the system into a shaded area to lower the temperature of the intake air.

Straighten the path

Sharp bends or narrow delivery lines can increase friction and the number of pressure drops in the system. Implement a straighter path into the system to get higher pressure, thus reducing the overall amount of energy required to compress the air.

Use several small compressors

Larger air compressors consume more energy per unit while working with only a partial load, thus making it inefficient. Try using multiple smaller air compressors with sequencing controls so that you can shut down portions of the system just by turning off some of the compressors.

Other practices that help your air compressor perform at optimal efficiency are:

Maintaining the compressor

Regularly check the air compressor system for any leaks, premature wear and tear, and the build-up of contaminants. Ensure that procedures are in place and train employees to operate the system properly.

Changing filters

Filters make sure that only the cleanest air reaches users. However, these filters may get clogged up with dirt, grease, dust, and other contaminants. Clean them often so that the system does not consume more energy to function due to a pressure drop as a result of clogged filters. You can also deploy longer-life and low pressure drop filters of a size suited to the maximum flow rate.The above practices will go a long way in achieving efficiency, performance, and quality of your air compressor system.

Top 5 Ways To Minimise Your Compressed Air Costs

by vemcoblogs -

Air compression if not done with proper checks, maintenance, and energy audits could turn out to be a fairly costly affair. To control costs of air compression effectively, you must follow a checklist of critical factors. While most of these factors fall under your regular maintenance procedures, some require your special attention. In this blog, we take you through the most important measures meant to control costs while you compress air at your facility.

  • Avoid unnecessary running: The biggest overhead cost associated with air compressors is the energy cost. There is one simple trick that you can use to tackle this upfront: turn it off! Air compressors at most facilities are used during the business hours and yet these are often found running until late evening. This wastes precious hours of electricity and adds to your energy bills.
  • Look for leakages: Leakages in the piping can cause loss of air pressure although the energy expended on compressing the air might remain the same. This means that you are using the same amount of energy but getting lesser work done. It is extremely important to look for leakages due to corrosion, pipe breakage, sludge, and dust particles in the piping regularly. Keeping the piping clean reduces the likelihood of leakages caused by corrosion.
  • Use the right pressure levels: Using the compressor at pressure levels beyond your requirement can cause wastage of energy. One reason for turning up the pressure could be compensating for the loss of pressure due to leakages, clogged filters, and other piping problems.
  • Use proper piping infrastructure: Using the right piping infrastructure that determines the direction and pattern of flow of compressed air is essential. A variety of factors play a role in this regard. Getting the compressed air to the focal point through a short pipe can optimise pressure and reduce energy use. Similarly, reducing the diameter of the pipe can help increase air pressure, work on the focal point effectively, and reduce energy consumption significantly.
  • Recover heat: The heat generated as part of the compression process can be used for a number of productive purposes. These include warming the rooms or producing hot water in washrooms. This could indirectly reduce the energy that would otherwise be consumed by geysers and radiators, especially in colder regions.
  • Ensure proper maintenance: By and large, proper maintenance helps reduce operational costs in more ways than one. In fact, preventive maintenance is less expensive than breakdown maintenance which could result in halting of operations and loss of business.

These insights can help keep a check on the energy, operations, and maintenance costs of compressing air at your facility.

Oil-lubricated or oil-free air compressors – which one should you pick?

by vemcoblogs -

Amongst a diverse set of criteria that you need to keep in mind while choosing your air compressor, the type of lubrication is one of the most important factors. Should you choose an oil-lubricated or an oil-free air compressor for your business operations? Well, the choice largely depends upon the type of industry you are in, the operations you carry out, and the specific role your pump is expected to play in your facility. All these factors are decisive in choosing the lubrication type for your air compressor. But first, you must gain a deeper understanding of both types of air compressors, and then decide whether they suit your purpose. In this blog, we do just that.

Oil-lubricated air compressors

Oil plays a crucial role in these compressors on multiple fronts. Of course, it keeps the moving parts in good condition by reducing unwanted friction. But it also plays the crucial role of dissipating the extra heat generated in the system. Besides, it offers to seal and helps in noise reduction. As these compressors are also available in piston technology, their efficiency, robustness, and ability to work quietly make them effective for a variety of pneumatic tools and accessories. Oil-lubricated air compressors find use in manufacturing, construction, recycling, waste management, and quarrying.

Oil-free air compressors

These compressors do not use oil for lubrication. Instead, their cylinders are coated with a material like Polytetrafluoroethylene (PTFE) which allows the piston to slide in smoothly. Since no oil is involved, the quality of air from these compressors is the same as that which goes in. As such, these compressors find tremendous application in processes where the air must be devoid of moisture or oil vapour. Here is a list of areas that prefer oil-free air compressors:

  • Food & beverage processing
  • Pharmaceutical manufacturing
  • Operating ventilators, surgical machines, inhaled medication systems (only for breathing air certified machines), and other critical equipment in hospitals
  • Semiconductor and electronics manufacturing
  • Automotive spray painting
  • Textile manufacturing

The oil-lubricated air compressors are on average more durable, efficient, and less noisy. These are preferred any day over oil-free compressors if the quality of air is not a precondition. However, regular oil changing is an overhead that comes as part of the package and marginally increases their maintenance costs. On the other hand, oil-free compressors have the sharpest focus on air quality and also have a much lesser carbon footprint. Having the benefit of both these perspectives, you can now make a well-informed choice between the types of air compressors for your facility.

How To Calculate The Right CFM or Airflow For Air Compressors

by vemcoblogs -

CFM is the short form of Cubic Feet per Minute (cu ft/min) and as is evident, it has a volume and a time dimension to it. CFM is, in fact, a measurement of how fast air flows into or out of space. The higher the CFM, the higher is the pressure exerted by the tightly compressed air on a pneumatic tool.

Analogous to power, CFM reflects the compressor’s ability to perform work over a certain period of time. While there is no doubt that CFM is a very useful metric of your compressor’s performance, there is, however, a need to understand the concept and arrive at accurate calculations.

Let us first try to understand the relationship between CFM and PSI (Pounds per Square Inch). While the two may seem conceptually alike, they have fairly distinct implications. CFM is the rate of flow of compressed air through a given space. It has a time dimension and is, therefore, a more dynamic metric. On the other hand, PSI is more static and is basically a measure of the pressure created by the compressed air per unit area. CFM is the driver behind PSI, which in turn reflects the Force that a compressor can exert and the amount of work it can get done. Both CFM and PSI determine whether an air compressor can meet your workload demands as each piece of equipment has its own airflow requirement.

There are a number of websites and online calculators that offer a simple and quick calculation of CFM. All you need to do is to enter the variables and within a split second, you arrive at your CFM. However, to gain a deep conceptual understanding of CFM, it is always advisable to do some good old math and arrive at the results through a formula. So, here we go:

CFM = Tank Volume in Cubic Feet x Standard Pressure (ATM) during a Cycle x Cranks per Minute

How to calculate Standard Pressure and Cranks per Minute?

Standard pressure must always be converted to PSI. Remember, 1 ATM = 14.7 PSI

Let’s say, your tank volume is 18 Cu. Ft, Standard pressure is 2 PSI and Cranks per Minute is 1.5.

By simple multiplication of the above-given variables, we get:

18 x 2 x 1.5 = 54 CFM

Another very easy method of calculating CFM is the airflow meter. This gives us the pressure coming out of a fitting and can be installed on individual pieces of equipment or complete systems to provide an instant reading.

If water, electricity and gas form the trio of essential utilities of the modern world, compressed air has a strong claim to be the fourth one. Air is one of the most ubiquitous resources of nature. When it comes to utilizing it as a source of energy, however, you have to compress and direct it with precision. Compressed air can drive wide-ranging activities and find use in a number of sectors. In this blog, we take you through the importance of this powerful source of energy across the economy.

Manufacturing:

Compressed air finds utility in a number of activities in the manufacturing sector. It powers the actuators, conveyor belts, sprayers and clamping equipment. It also supports casting processes, offers optimal product finishes and helps clean the final products impeccably. 

Construction:

Another sector that requires some heavy lifting and muscle power is construction. Compressed air is used to power pneumatic tools like buffing equipment, nailing, stapling and riveting guns, grinders, drillers, jackhammers and sanders. Lowering and raising heavy loads or demolishing structures also make use of compressed air. Tunnel-digging is another area where compressed air does wonder. They are used for road digging, cutting and cleaning. They also keep the tarmac, debris and other hard surfaces debris-free. 

Agriculture:

Pruning, harvesting, crop fertilising, seed sprinkling and spraying are some of the activities that compressed air helps with, in the agricultural sector. Air compressors power the tractors, sprayers, conveyors and pneumatic fruit pickers. They also facilitate the operation of hydraulic pumps.

Healthcare:

Compressed air is used for administering anaesthesia, power ventilators and other surgical machines in operation theatres. Compressed air is always free of contaminants, pollutants and other particulate matter, making it extremely useful to maintain an allergy and infection-free healthcare facility. Compressed air is also used to inflate emergency mattresses for patients.

Automotive:

In this sector, air compressors find great use in engine construction, assembling car bodies and giving finishing touches to the cars. Intricate components are put in place using compressed air-based pneumatic tools. Plasma cutting, welding and inflating tyres also use compressed air. Finally, the air compressors are used to clean the car and paint it using dry and oil-free compressed air to prevent bubbles or splattering to form on the surface.

The above-given list is not exhaustive and air compressors are used in multiple other areas of the economy. In the future, as the efficiency, precision and power of the pneumatic instruments is improved, air compressors are expected to find the greater application and have an increasingly enlarged role to play.
