How Does a 2 Stage Air Compressor Work?

2 stage air compressor features a piston that’s connected towards the crankshaft by such a connecting rod. The piston goes forward as well as backward as the crankshaft turns it.

The crankcase and the crankshaft are connected by the crankcase. The input and exhaust valves are both attached to a cylinder head with a valve cavity.

p-v diagram

PC: mechanicalboost

A 2-stage air compressor is seen in the P-V diagram you can see above. The following is how a two-stage air compressor actually works:

  • The crankshaft revolves as prime mover, which is linked with a crankshaft, begins to rotate. The crankshaft’s movement also initiates the reciprocating action of the piston during the first cylinders (L.P cylinder).
  • The piston suctions air through into the suction valves and filters throughout that procedure. The air is compressed by the pistons of low-pressure (L.P) cylinders. Then compressed air inside the L.P cylinder being pressurized to an intermediary pressure “P2.”
  • The pistons of an L.P cylinder compress the air to a specified degree before sending this to an intermediary pressure (I.P) air cooler, in which it is getting cooled (as illustrated in the image below) before being sent to the next (H.P) cylinder. The ratio of each compression in the first stage is determined by the amount of cooling needed.
  • The piston of the H.P cylinder swings forward and downwards during the air compression process, converting the air into high pressured air. The high-pressured air is finally collected through the output valve.

2 Stage Air Compressor Construction

The basic constructions of the 2-stage air compressor are the electric motor, its diagram, and belt.


Electrical motors are commonly utilized to give power and energy to the compressors. As a prime mover, the motor’s job is to provide enough power to begin the compressor, drive that to high speed, and then keep it running under multiple design conditions.

Typical three induction electric motors are used in most compressor. Premium types with the high-efficiency motor should have been specified over conventional motors for custom-designed air compressors.

The additional expense of a premium and high-efficiency motor that is typically soon recouped through energy savings.


To further understand the conceptual air compressor diagram, consider the image below;

air compressor diagram

PC: brighthubengineering


The air get compressed polytropically when the piston rises (PVn= C). From P1 to P2, overall air pressure rises, and from V1 to V2, its volume falls. From the point T1 to T2, the temperature goes up.


The compressor delivers compressed air towards the air receivers at the specified pressure P2, volumes V2, and the temperature T2.


Air is drawn from of the air by that of each air compressor. P1 is indeed the air pressure. So when pistons are at their highest point, the volume is zero.

As a result, a volume of the air V1 is sucked through into the compressor even as the movement of the piston starts from the top to the bottom. T1 is indeed the air temperature.


A 2-stage air compressor is also known as a belt-driven compressor made up of belts attached to such compressors pump’s motor. The belt rotates whenever the motor is turned on, generating the pump that connects to the 2-stage air compressor.

When operating a motor-driven air compressor, its crankshaft gets mechanically powered by an electric motor of the compressor.

2 Stage Air Compressor Pump- 3hp/ 5hp/ 7.5hp

HP stands for horsepower, or perhaps the volume of work that a motor can do.

When it comes to assessing if the compressor will perform for you, horsepower is less significant than pressure and the flow because new or significantly improved compressors can accomplish more with less horsepower.

3 HP: A 3 hp air compressor requires a 2.3 kW motor, which assuming 98 percent effectiveness, which is improbable. Then there’s the maximum power, which really is normally around.8 for most conventional motors.

That takes the total power need to 3.15 kVA.  For the 3 hp air compressor to get started, you require roughly 19kVA of generation.

However, you only use 3 of such a 19kVA while the compressor is working, which would be 17% of something like the generator’s capacity.

5 HP: 2-stage air compressors with a capacity of 5 hp is powerful and flexible equipment. 5 hp 2-stage air compressors are available in a multitude of classes, CFM outputs, as well as compressor designs to fulfill the needs of practically every project.

Those 5 hp 2-stage air compressors come in a variety of grades, from consumers to the commercial, all using the two stages of air compression to do is provide double the pressure and efficiency.

7HP: A 7.5hp air compressor can be a terrific addition to your workshop or garages, but few people are aware of its existence. It’s a prevalent misperception believing air compressors really are big manufacturing devices.

Indeed, air compressors exist in a variety of sizes, some of which are best suited for different customer use, such as 7.5hp air compressors.

Classification by Capacity

If we classify the 2 stage air compressor, we will find out three capacities, that is, 30-gallon two-stage air compressor, 60 gallons two-stage air compressor, and 80 gallons two-stage air compressor.

30 gallon Two Stage Air Compressor

For the commercial or contractor, its dual voltages motor permits the machine to run on either 120V or 240V.

60 gallon Two Stage Air Compressor

A 60-gallon air compressor seems to be more cost-effective than other solutions for powering pneumatic machines. Workshops enthusiasts, small construction enterprises, hobbyists, and experienced or professionals will benefit from them.

These devices are capable of doing any type of job task. They can store compressed air for such a long time period due to the cast-iron tank.

80 gallon Two Stage Air Compressor

An 80-gallon air compressor is commonly used in construction work, home remodeling, and by smaller mechanical companies.

In the shop, there’s a stationary as well as a portable 80-gallon compressor—this air compressor is primarily designed to provide maximum industrial performance.

  • Pounds Per Square Inch (PSI)
  • Cubic Feet Per Minute (CFM)
  • Horse Power (HP

Pounds Per Square Inch (PSI)

Mostly 90 PSI is the least pressure for an air tool to function. Pound per square refers to the internal force that comes out.

The buyer has to focus on the exact CFM on which the PSI reaches 90.

Cubic Feet Per Minute (CFI)

This describes the air volume passing through the compressor at a certain time. We recommend having a higher CFM compressor to buy because of the intensity and power of the machine.

Buy a compressor with a higher CFI than your project requires. Someday, you might have another project to work on with high CFI. In that case, you can use your air compressor and finish the project at ease.
