3 Must-Have Compressed Air System Accessories That Improve Performance

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.

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

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.


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.

6 Air Compressor Maintenance Tips to Avoid Breakdown

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.

What are the Basic Reciprocating Compressor Components?

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:


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 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. 


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. 


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.


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 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.

Why My Air Compressor Is Losing Pressure?

What is Compressed Air Pressure Drop and How Do You Minimize It -  Fluid-Aire Dynamics

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

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.
