Air compressors find many applications in industry and are used in a wide variety of fields including automation and installation, chemical manufacturing, agriculture, and construction.
All compressors work by converting electricity from an external source such as an electric motor or diesel engine into stored energy which can be released in the form of compressed air. You can also get more information about air compressors via the web.

Choosing the right air compressor
However, compressors differ in how they work, the capacity of the air, and the pressure they can provide. A suitable compressor can hold enough air and provide a pressure level high enough for the task, but performance must be considered with considerations such as cost and durability.
Types of industrial air compressors
There are three main types of industrial air compressors based on how they work. These are reciprocating compressors, screw compressors, and radial compressors.
Shuttle service
A piston compressor is a positive displacement compressor whose air volume decreases to increase its pressure. A piston contains a pump that is driven by a piston with a cylinder that compresses and replaces air.
Rotary screw
The rotary screw air compressor also works using a positive displacement process. They use two propellers linked together to let air in and compress it.
The way it works is a smoother process than a piston, with excess stress and less vibration than sometimes a piston compressor. They are durable and easy to care for.
Rotary screw air compressors usually have a larger capacity than reciprocating compressors and can produce higher air pressure. Some types have a frequency converter, which means that airflow and pressure can be precisely controlled.
Centrifugal
Centrifugal air compressors work according to a different mechanism. They use the inertia of the rotating disc to transfer and compress air. This process is known as dynamic shifting and is a continuous process that results in a constant supply of compressed air.
