Air Compressor :-

  • Air Compressor are machines that convert one form of energy into another form, which can then be stored and used at a later point in time.

  • An air compressor is a pneumatic device that converts power (using an electric motor, diesel, or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air).

  • By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank’s pressure reaches its engineered upper limit, the air compressor shuts off.



How and Why Air is Compressed ?

  • To understand the importance of compressed air – and the compressors that generate it – let’s first take a closer look at the physics of it. Compressed air is simply regular air that is forced into a much smaller space. When this happens, its molecules speed up and so-called “kinetic energy” is created. That kinetic energy can either be used right away or it can be stored and released later.

  • One of the reasons compressed air has become so indispensable is its versatility. Just about every industry relies on compressed air in some form – from manufacturing plants to cars, ships and trains, construction sites to hospitals, compressed air is used all around it.

  • With so many different applications, it also makes sense that there are many different types of air compressors. After all, the small and quiet compressor that powers a dentist’s drill should not be the same as the industrial compressor that keeps an entire manufacturing plant going.



Types of Air Compressor :-

According to the Pressure Delivered

  1. low-Pressure Air Compressors (LPACs): They can discharge pressure at 151 psi or less.
  2. Medium-Pressure Air Compressors: It can discharge pressure in between 151 psi to 1000 psi.
  3. High-Pressure Air Compressors (HPACs): they are having discharge pressure above 1000 psi.


According to the Type of Compression, It can be Classified as

  1. Positive Displacement : Piston type, rotary screw, rotary vane air compressor
  2. Dynamic Displacement: Centrifugal and axial flow air compressor
