Different Types of Air Compressors

Executive Summary about Air Compressor by Prasanna Sutrave

The two main classification of Air Compressor are:

01) Positive Displacement Type

02) Dynamic Type.

01) Positive Displacement Type Air Compressor.

This types of Air Compressor further classified as

A) Reciprocating Air Compressor.

B) Rotary Air Compressor.

In this type, air is compressed by two rotating or inter meshing rotors. According to the type of construction Rotary Compressor can be further classified as (a) Rotary Screw Compressor (b) Rotary Vane compressor.

(a) Rotary Screw Compressor.

(b) Rotary Vane compressor.

This type of Air Compressor can be further classified as Single Stage or Double Stage Rotary Air Compressor.

02) Dynamic Type Air Compressor.

The Dynamic Type Air Compressors mechanically impart velocity to the air. This type of compressor is further classified as (a) Centrifugal Air Compressor (b) Axial Flow Air Compressor (c) Roots Blower Compressor.

(a) Centrifugal Air Compressor.

(b) Axial Flow Air Compressor.

The Axial Flow Type Air Compressor is essentially a large capacity, high speed machine with characteristics quite different from the centrifugal air compressor. (c) Roots Blower Compressor.

The discharge air pressure obtained from this type of machine is very low.
