Industrial Air Compressor: Application, Uses & Working

Industry-used air compressors are very different from your regular home-used air compressor. If you are unaware of industrial air compressors’ features and capabilities, it would be tough to use them in the industry.

How does compressed air work? 

The compressed air basics are apparent. Compressed air is only air that is held under pressure more significant than the atmosphere. Compressed air technology has been around for decades, but it has progressed like any other technology. It is commonly used commercially and residentially, but compressed air technology’s industrial applications are enormous.

 An air compressor functions similarly to that of your car engine. Pistons press down on a combination of air and gasoline in your car engine. The mixture compresses and then ignites, which generates energy. An air compressor does the same thing, in the simplest form. A piston forces air down in the compressor, pressurizes it, and stores it in the underlying tank. The air compressor used today can hold vast quantities of pressurized air in its tanks because of technology.

Most Common Industry Applications

Air compressors are used in various industrial applications, from the production of pharmaceuticals and food and beverages to nuclear power and the production of chemicals and petrochemicals. The design, engineering, and service capabilities provide a broad cross-section of industries with efficient operations and cost savings. Industries that routinely use highly compressed air volumes include the following:

Petrochemical / Chemical

Chemical & petrochemical plants require compressed air of very high quality. Additionally, these plants also choose inherently safe systems regardless of the unsafe environments that might occur.


As with the chemical and petrochemical industries, there are stringent criteria for compressed air for pharmaceutical applications. It is essential to provide compressed air of the highest quality, especially when the air contacts raw materials or finished products.

Food and Beverage

Again, the Food and Beverage Industries demand high-purity air supplied consistently as with pharmaceuticals. The atmosphere that could come into contact with the substance of food or drink must be safe.


In general, compressed air quality may vary widely in manufacturing applications, depending on the use. Some applications need an air of general-purpose, while others require a mixture of general-purpose and instrument grades of higher quality.

Metal Manufacturing

Air compressors are used for several processes at the finishing end at metal production plants. Pressurized air is used as newly shaped metals take shape to power the pneumatic tools that cut raw metal supplies into measured lengths and specified conditions. The grinding tools that smooth out and clean the surfaces of metal items are often used by air compressors to power them.

 Ships Building

The shipbuilding processes involve a complex arsenal of instruments and machinery, many of which depend on air compressors. Air-powered tools are used to cut the pieces, smooth the surfaces, refine the edges, and attach separate components into one during shipbuilding phases where the parts are made. Further rounds of pneumatic tools are used after the assembly stages to paint and apply finishes to different naval vessel details.


Energy Air is, first of all, used to store and transfer energy for mechanical work. It is used to power pneumatic manufacturing machinery, air-operated lathe chucks, pressure clean parts, and manufacturing to convey or cool components.

On the other hand, active air is needed as a dynamic and integral part of a specific method. In this situation, the air comes into contact with the product; the air quality is, therefore, essential.  The air compressor dealers in Navi Mumbai ensure clean, dry air quality, or CDA quality for short, is improved using oil-free compressors and treating the air using one of the many quality air tools available. 

5 Basic Questions Need to Ask Before Purchasing the Air Compressor

A compressor has a wide variety of applications in various businesses and manufacturing industries. When you think about an air compressor, the one thing that pops in mind is that it is present at almost every shop from the garage to the dentist’s office. The popularity of the compressor is because it is reliable and can work in virtually any setup and keep well to the pace. But many a time people are made fools just because they don’t know anything about compressors while buying one. Here is a checklist of questions that will help buy a new compressor. Answering these questions will help in finalizing the right air compressor based on your needs.

What is the application for which the compressor is required?

The answer to this question decides the type of compressor that you are going to buy. The size of the compressor is determined by the most crucial factor that is the type of application you are using it. Also decide how long you intend to use the compressor whether it is 10 or 20 hours a day, five days a week, or only occasionally. Buy a perfect compressor like a screw compressor if your demands are consistent. If the needs are constant, get a compressor that is designed for a duty-cycle which equals or exceeds specified requirements.

Where will the compressor be placed?

The second main question that you have to answer before buying a compressor.

For example, if it is to be installed outdoors, the compressor would require superior protection against rain and heat. The compressor must have adequate ventilation for proper functioning since most reciprocating compressors are air-cooled. The compressor should not be placed inside of a closet. The closet, in most cases, won’t have enough ventilation to handle the heat produced by the compressor. Also, be mindful that sunlight doesn’t fall on the equipment and the noise generated it.

How much PSI do you require?

The PSI of the compressor will differ based on the type of work that you perform. The demand for compressor pressure depends on the needs of the tools that you are using. Check the system that requires the highest volume of air and use that as a reference to select the compressor. Also, be careful that you do not overpressure the system. Go according to the specification of the manufacturer. The pressure also determines whether the unit should be a single-stage or two-stage compressor.

How much airflow (CFM) does your operation require?

Cubic feet per minute or CFM is the measure of airflow created by the compressor. Sometimes the ideal volume of air is not exactly the ideal CFM ratings. In that case, take a load cycle on the existing compressor for all shifts if possible. Installing a flow meter on the new compressor for a nominal cost can save you thousands in the long run. Once you have determined your flow requirements, you can match that to consider the needs for future growth. Oversized compressors will use more power and increase the cost of power in the long run.

What is the type of control system that you need?

There are three variants of a control system that can be employed in a shop. The first is the start/stop system, the second is the constant speed control, and the last one is the dual control system. The Elgi air compressor has various types and will suit perfectly for your specifications.

Bottom line

Compressors help in maintaining the quality of the shop and efficiency. You can go for a screw air compressor that would be the best choice due to capabilities and functionality.

Working of ELGI Air Compressor

How ELGI air compressor works?

An air compressor is a device designed to pump compressed air. It is used to ensure the circulation of cooling refrigerant in a closed circuit, and the pumping of pressure into various containers. This equipment is widely used in medicine, industry, and household. Its presence allows you to perform a wide range of actions.

The principle of operation of the ELGI air compressor can be described as follows.

  • When the engine starts, the crankshaft begins to rotate, transmitting reciprocating movements through the connecting rod to the piston.
  • The piston, moving downward, creates a vacuum in the cylinder under the influence of which the inlet valve opens. Due to the difference in air pressure, it begins to be sucked into the cylinder. But before it enters the compression chamber, air passes through the filter.
  • Further, the piston starts to move up. In this case, both valves are in a closed state. At the time of compression, pressure begins to increase in the cylinder, and when it reaches a certain level, the exhaust valve opens.
  • After opening the exhaust valve, compressed air is directed to the receiver.
  • When a certain pressure has entered in the receiver, a pressure switch is activated, and air compression is suspended.
  • When the pressure in the receiver decreases to the set values, the pressure switch starts the engine again.

How to choose an industrial air compressor?

To select the right compressor, first of all, you need to determine how often it will be used, depending on your needs for compressed air.

You are also required to determine if you need a portable compressor or whether it will be used indoors. In this case, it is necessary to ensure good ventilation of the compressor to make sure that it has optimal cooling.

Also, consider the continuous running time of the compressor. Manufacturers usually indicate the duty cycle on these elements. This duty cycle allows you to determine the duration of the compressor for one hour. 

Purpose and principle of operation

What is an air compressor? This is a device designed to compress air and pump them to the required place. How does it work? The principle of operation of the ELGI compressor is quite simple; atmospheric air enters the mechanism that performs its compression. For this, different methods can be used. The mechanism that compresses the air determines the device and the principles of operation of the compressor. For the effective operation of the equipment, it must be connected to the electric network and the air network, through which compressed air will be transmitted. 

Common problems of air compressor

Unit overheating

Usually, the unit may overheat when operating in intensive mode or at an increased ambient temperature in the room. If the unit still overheats under standard operating conditions and normal room temperatures, then a clogged air filter may be the reason behind the malfunction. It should be removed and washed, then dry it properly.

Knock on the cylinder

It is caused by a breakdown or wear of the piston rings due to carbon deposits. Usually, it appears if you use low-quality oil. Knocking-in the cylinder can also be caused by wear on the connecting rod. These parts should be replaced with new ones. When the cylinder and piston are worn, repair of the air compressor consists of boring the cylinder and replacing the piston.

ELGI air compressors are very essential since they require small maintenance. Apart from that, they are highly reliable and huge. This is the reason why they are good for industrial applications. Ensure that you look for reputable dealers in the same product. You may opt for the ELGI air compressor dealers in Mumbaiwho are reliable and have the best products.
