What Are the Types of Air Compressors? – Shaktiman

An Air compressor is a device that converts power from diesel, electric, and gasoline engine into potential energy stored in compressed air. Based on the pressure delivered, types of air compressors are classified.

The Air Discharge Pressure of 150 pounds per square inch is under Low-pressure air compressors
The air discharge pressure of 151 to 1,000 pounds per square inch under Medium-pressure air compressors
The air discharge pressure is above 1,000 pounds per square inch under High-pressure air compressors

According to this threshold and work requirements, air compressor types are defined.

4 Most Common Types of Air Compressors and Their Uses

There are four common types of air compressors with their unique features & capabilities.

Rotary Screw Compressors
Reciprocating Air Compressors
Axial Compressors
Centrifugal Compressors

All the air compressors fall into two categories. One is Positive Displacement and another one is Dynamic Displacement.

The above 4 types of air compressors come under either Dynamic or Positive.

What Is Positive Displacement Air Compressor?

A mechanism of the Positive Displacement air compressor is to draw air into the chamber. Then the volume of this chamber decreases which will compress the air. A valve will open, and the air is then discharged into the outlet system once maximum pressure is reached. Rotary screws and reciprocating air compressors fall under this division.

What Is a Dynamic Displacement Air Compressor?

Dynamic Displacement air compressor speeds up the air to high velocity and then limits the airflow from the chamber. Because restriction in rate causes pressure to increase. Axial Compressors and Centrifugal Compressors fall under this division.

1. Rotary Screw Compressors

Rotary Screw Air Compressors are compressors that use the mechanism of rotary-type positive displacement mechanism. It mostly comes to replace piston air compressors in industrial areas. Because the industrial application needs a large amount of compressed air.

2. Reciprocating Air Compressors

A reciprocating air compressor is also the type of positive displacement compressor in which air is sucked into a chamber and compressed with the help of a reciprocating piston. There are four kinds of Reciprocating Air Compressors

Single acting Reciprocating air compressor
Double-acting Reciprocating air compressor
Single-stage Reciprocating air compressor
Double-stage Reciprocating air compressor.

3. Axial Compressors

An axial Air Compressor is an air flow-based air compressor in which airflow or gas flows parallel the axis of rotation, or axially. It converts the circumferential component of flow into pressure with the help of the stationary blades to slow the fluid.

4. Centrifugal Compressors

Sometimes Centrifugal air compressor is also called radial compressors or impeller compressors. By adding energy to the continuous flow of fluid through the impeller, high pressure is achieved.

These are the four types of air compressor and their work mechanisms. Based on the requirement of your business you can buy suitable air compressors from the right air compressor dealers.

Everyone in the business field has this major question in their mind Should I buy a Reciprocating or a Rotary screw? Mutually both of the compressors create compressed air but it depends upon the application so we will explain it briefly.

What Is the Dissimilarity between the Reciprocating Air Compressor and Rotary Screw?

Both of the compressors produce compressed air utilizing positive displacement, These compressors compress air mechanically to reduce its volume but the mechanics or engine is different.

Reciprocating Air Compressor

This air compressor is also known as a piston air compressor.

Pistons were used in the mid-1600s, Now these are largely used in industry, and Similarly, the same compressor was used during the 1800s

The reciprocating air compressor engines are systematic and easy to maintain. They are adequate for applications.

Rotary Screw Air Compressor

Rotary screw air compressors have been about since the mid-1900s. There are two rotors and a compressed air system present in the Rotary screw air compressor.

The air is pulled into the chamber and squeezed into a smaller space. The rotors turn and are continuously compressed in this process. There are a few moving parts in the rotary screw air compressor and mainly this air compressor is more reliable.

Which Is the Best Reciprocating Compressor or Rotary Compressor?

Reciprocating or Rotary doesn’t matter and it’s all depending upon how the compress is used? How much compressed you need and the environment is also part of it.

Mainly you want to know about the pros and cons of Reciprocating or Rotary compressor

Reciprocating Air Compressor & Rotary Air Compressor

Pros of Reciprocating Pros

Both have pros and as well as cons so it depends upon the situation and also depends upon your application

When to Use a Reciprocating?

This is the type of air compressor which is best for when the air is worked intermittently by using short bursts. The reciprocating air compressor is the best little machine shop, building sites, and other small companies. This compressor is to run blow off and cleaning, sandblasting, airbrushing, Check Tire Pressure.

There is one main advantage of this air compressor is when the compressor is running continuously or at maximum capacity, it will not be damaged.

It’s being sized by 50% higher than the actual CFM to let the compressor avoid excessive heat from the motor.

When to Use a Rotary?

A rotary screw air compressor is best for heavy-duty work and continuous air and it is otherwise called a heavy-duty air compressor. These are the pillars of industry, big construction, and road construction work. It is designed to produce continuous air and flow of consistent air.

Mainly the air produced by the rotary is cleaner than the reciprocating and mostly it is the best choice for paint tubes and packaging.

Rotary screw compressors can work under extreme conditions like high temperature or lower temperature the machines can work in urban-rural areas.

They are designed to have more power and extremely high tools and are easier to maintain. The rotary screw air compressor has 70% fewer parts and it turns lower maintenance.
