Overview
An air compressor is a versatile and powerful tool that is used in various industries and households for a wide range of applications. It works by converting power from a motor or engine into potential energy stored in pressurized air. This pressurized air can then be used to power pneumatic tools, inflate tires and sports equipment, paint and spray, clean surfaces, and much more.
Definition of an air compressor
An air compressor is a mechanical device that compresses air and stores it in a tank or cylinder. It consists of a motor or engine that drives a piston or rotor, which compresses the air and forces it into a storage tank. The compressed air can then be released at the desired pressure when needed.
History of air compressors
The history of air compressors can be traced back to ancient times when humans used bellows to blow air into fires. However, the development of modern air compressors began in the 17th century with the invention of the air pump by Otto von Guericke. This paved the way for further advancements in air compression technology, leading to the creation of reciprocating air compressors, rotary screw air compressors, and centrifugal air compressors.
Types of air compressors
There are three main types of air compressors: reciprocating, rotary screw, and centrifugal.

Rotary screw air compressors
Rotary screw air compressors are popular in industrial applications due to their continuous operation and high performance. They use two interlocking screws to compress the air, eliminating the need for pistons. The air is then discharged at the desired pressure. These compressors are widely used in manufacturing plants, automotive workshops, and construction sites.
Centrifugal air compressors
Centrifugal air compressors are mainly used in large-scale applications that require high volumes of compressed air. They work by using an impeller to increase the air’s velocity, which is then converted into pressure by a diffuser. These compressors are commonly found in power plants, oil refineries, and chemical plants.
Working principle
The working principle of an air compressor involves several key components and processes.
Inlet and outlet valves
The inlet valve allows atmospheric air to enter the compressor, while the outlet valve controls the release of compressed air from the storage tank. These valves ensure proper air flow and pressure regulation.
Piston movement or rotor rotation
In reciprocating air compressors, the piston moves up and down to compress the air. In rotary screw compressors, the interlocking screws rotate in opposite directions, trapping and compressing the air.
Compression of air
As the piston moves or the screws rotate, the air is compressed, reducing its volume and increasing its pressure. This is achieved by confining the air within a smaller space, forcing its molecules closer together.
Discharge of compressed air
Once the air is compressed, it is stored in a tank or discharged directly for immediate use. The compressed air can be released at the desired pressure through various outlets and connections.
