Choosing The Right Air Compressor: A Comprehensive Guide

Air compressors are machines that compress air in order to store it or to power tools. Air compressor's are commonly used in manufacturing because they provide a reliable source of compressed air, which is often used in many applications such as to power variety of air tools / pneumatic tools like heavy-duty air wrench, inflators, nailers, couplers using air hoses.

 Air compressors come in a variety of sizes and types (cfm rating), so they can be matched to the specific needs of a manufacturing facility.

They are used in combination with large tanks to store the air pressure. Stored air in the tank can be used when required for a variety of applications, from powering air tools, conveying materials to driving pneumatic machines.

Compressed air is a very important resource in industry, often being referred to as the "fourth utility". Many factories, from small machine shops to gigantic pulp and paper mills, use some type of compressed air system which is often crucial to the operation of the facility.

The size of a plant's air compressor system can range from a small unit of 5 horsepower (hp) to a massive system with 50,000 hp or more.

What is an air compressor?

A air/gas compressor is a machine that transforms energy from a turbine, Engine or a electric motor into potential energy stored in pressurized air using volumetric , dynamic or axial method of compression. This Pressurized air (compressed air) can then be used to operate production machines including powering pneumatic tools, blowing up inflatable objects etc.

How do air compressors work?

A positive-displacement type of compressor traps a given quantity of air or gas in a compression chamber, and then mechanically reduces the volume which it occupies. This causes the pressure to rise before it is discharged. Maintaining a constant speed will keep the airflow steady, even with changes in discharge pressure.


Dynamic compressors use impellers that rotate at high speed to transfer kinetic energy from moving air or gas to create pressure. This process happens in the impellers and the discharge volutes or diffusers.

What is the function of air compressor?

Air compressors are used in manufacturing units to provide compressed air for various applications. The most common use is to power pneumatic tools, but they can also be used to operate other machinery, such as air cylinders and air pumps. In some cases, air compressors are also used to generate electricity.

What are the major types of air compressors?

Air Compressors can be classified in different types based on the method employed for their operation or power source (Electric Air compressors or motor driven air compressors, Engine driven air compressors or Portable air compressors, Turbine driven Air compressors, principle of operation ( positive displacement Air compressor or dynamic Air compressor ) or,

Type of Construction (Screw Air Compressor, Scroll Air Compressor, Centrifugal Air Compressor, Reciprocating Air compressor) and so on.

What do we mean by Air compressor Specifications

Air compressor features (CFM, Horsepower, Scfm, Psi, Oil Free)

Air compressor specifications or features refer to the characteristics and capabilities of a particular air compressor model. This includes details such as the capacity, power output, operating pressure, flow rate and sound level. It is important to consider these factors when selecting an air compressor as they will determine its suitability for specific tasks.


Capacity is measured in cubic feet per minute (CFM) and relates to how much air can be compressed by the machine at one time. Power output is measured in kilowatts (kW) or Horsepower and describes how much energy is required to run the machine.


Operating pressure refers to the amount of pressure that can be produced by the compressor or in simple words it is the pressure the compressor can deliver (psi - Pounds per square inch) , while flow rate describes how quickly air can be moved through the machine.


Finally, sound level indicates how loud the machine will be when it is running. With all these factors taken into consideration, it’s possible to select an air compressor that meets your requirements perfectly.

Electric Air Compressors (Electric Motor as power source)

Electric air compressors are a type of air compressor that uses electricity to power the unit using a Electric Motor. These compressors are often used in applications where portability is not a concern, as they tend to be larger and heavier than other types of air compressors.

Engine Driven Air Compressor (Portable air compressors)

An engine driven air compressor is a type of air compressor that uses an internal combustion engine to power its operation. These types of compressors are normally used as a movable setup (high portability) on a frame or a vehicle and are also known as Portable Compressors.

Engine driven air compressors comes in different size and capacity to be used at places where electrical energy is not available or for application where the location of machine is not fixed and requires high portability.

Turbine Driven Air Compressor

A turbine driven air compressor is a machine that uses a turbine to drive an air compressor. The turbine drives the compressor by turning a shaft that is connected to the compressor. The compressor then pumps air into a tank. The turbine driven air compressor is a very efficient way to compress air.

Classification of air compressors

Air Compressors can be broadly classified in two types based on the principle of operation, Positive Displacement and dynamic compressors.

Positive Displacement Air Compressors

 There are two types of Positive Displacement compressors: rotory type consisting of screw scroll etc and reciprocating type . With a piston moving up and down in a cylinder. Piston compressors work in a similar way to pumps, with a piston moving up and down inside a cylinder.

A piston, powered using an electric motor through a crank shaft and connecting rod, decreases the volume of air/gas in a cylinder, building up potential energy. The size of a reciprocating compressor can ranges from less than 5 hp to more than 2500 hp. Rotary compressors are now commonly used in industry, especially for capacity of 5 hp to 500 hp.

The most popular type of rotary compressor is the screw type (also known as rotary screw). Male and female screw rotors interlock, trapping air, reducing the volume of the air along the rotors length to the air discharge point. Rotary screw compressors have a low purchase price, small size, and light weight.

They are also easy to care for. Rotary screw compressors can be cooled with air or water. Sliding-vane, liquid-ring, and scroll-type compressors are less common.

Dynamic Air Compressors

The pressure of air or gas is increased by dynamic compressors by giving it kinetic energy and transforming it to pressure/potential energy. Dynamic compressors include axial and centrifugal compressor types. The most common type of compressor is the centrifugal compressor.

This type of compressors are preferably used for industrial compressed air requirements. Impeller's, rotating at a very high speed (35,000 rpm to 65,000 rpm) , gives the air/gas high kinetic velocity which then goes through a diffuser to convert it into pressure energy (7 bar or more). Manufacturing plants can utilize centrifugal compressors for plant air requirements.

Air Compressor types

Positive Displacement and Dynamic compressors can further be classified based on their construction as Reciprocating compressors, Rotary compressors, Centrifugal compressors, Axial Compressors.

Reciprocating sir compressors can be single acting, double acting or multistage. Similarly Rotary compressors can be screw compressor, Scroll compressor, Lobe compressor etc.

Reciprocating Air Compressors

In a Reciprocating air compressor, air is compressed by a piston moving up and down in a cylinder. The air is drawn into the cylinder through an inlet valve at the bottom of the cylinder. The air is then compressed by the piston moving up in the cylinder. The compressed air is then discharged through an outlet valve at the top of the cylinder.

Screw Air Compressors (Rotary Air Compressor)

A rotary type screw compressor is a stationary air compressor contains two rotors that fit together and are surrounded by a housing. The housing contains an inlet port and a discharge port at opposite ends.

The male rotor contains spiral-shaped lobes whereas the female rotor has matching spiral-shaped grooves (which can be lubrication type or oil-free). Different designs of rotary compressors may have a varying number of spiral lobes and grooves.

Air flows inside the chamber through the inlet port and is trapped between the lobes of the rotating rotors and the housing. The point of intermeshing moves along the length of the rotors, reducing the space occupied by the air thus increasing pressure. When the space between the lobes is exposed to the outlet, the compressed air is released.

Scroll Air Compressors

Scroll air compressors are a type of compressor that uses two interleaved scrolls to trap and compress air. These compressors are typically more efficient than reciprocating piston compressors, and are often used in applications where compressed air is required on a continuous basis, such as in factories.

A centrifugal air compressor has a stream of air that constantly flows (measured in CFM) and picks up kinetic energy by spinning on an impeller. The air is then sent to a diffuser where the air slows down and changes to pressure energy (measured in PSI). Centrifugal compressors are best suited for high volume applications, such as factories and plants.

Centrifugal air compressor

Axial Flow Air Compressors

Axial flow air compressors are some of the most efficient compression devices available. By compressing air along the axis of the compressor, these units can achieve very high levels of compression with minimal energy consumption. Additionally, axial flow air compressors tend to be very quiet and vibration-free, making them ideal for use in a wide range of settings.

Axial flow air compressor

What are some brands of compressors?

Major air compressor suppliers usually manufacture a range of air compressor types and models to suit different customer needs. Some of the most popular brands include Cameron, Ingersoll-Rand, Sullair, and Atlas Copco. These companies typically have a global reach and sell their products through a network of authorized distributors.
