Centrifugal compressors operate at higher speeds compared to positive displacement compressors offering greater volumes of constant, high-pressured air.

Air compressors are like a one-size fit all type of device for applications involving pressurized air.

From powering pneumatic tools to sourcing heating and cooling control systems, an air compressor brings mechanisms to life with the help of a motor or engine to forcefully push high-pressured air.

Here is a rundown on the main three types of air compressors in the industrial market. For more a detailed specification of air compressors, contact us at www.mcraeeng.com.

Reciprocating compressors

Reciprocating air compressors are positive displacement mechanisms, which is defined as machines raising its air pressure while simultaneously dropping its volume. This type of compressor takes in consecutive bouts of air in an enclosed space while escalating the air at a higher pressure, which is carried out by a piston inside a cylinder engaged as the compressing and displacing component.

Designed with either a single-stage or two-stage configuration, reciprocating air compressors handle pressures ranging from 70 psig (pounds per square inch gauge) to 250 psig.

Rotary screw compressors

Commonly referred to as screw air compressor, rotary screw compressors are one of the most widely used positive displacement compressors because of its easy maintenance and operation.

One reason for this is these particular compressors have built-in cooling systems inside the unit, which provides consistent operating temperature when running. This continuous operation feature is a win-win as a high performance device while offering low maintenance of its internal components.

Designed with two rotors that compress the air internally, rotary screw compressors come either as a single stage helical or spiral lobe oil air compressor. Both options use air cooled or water cooled oil coolers with capacity and speed controls to offer increased volume production with a long service life.

Centrifugal compressors

This type of compressor offers dynamic displacement, meaning its production of high-pressured air is contingent on a rotating impeller, which uses momentum at an angle. Centrifugal compressors operate at higher speeds compared to positive displacement compressors offering greater volumes of constant, high-pressured air.
