Compressor:
A compressor is a mechanical device that increases the pressure of a gas or Air by reducing its volume.

Centrifugal compressors:
Centrifugal compressors use a rotating disk or impeller in a shaped housing to force the gas to the rim of the impeller, increasing the velocity of the gas.

Axial-flow compressors:
Axial flow dynamic compressors are dynamic rotating compressors that use arrays of fan-like airfoils to progressively compress the working fluid. They are used where there is a requirement for a high flow rate or a compact design.

Reciprocating compressors
Reciprocating compressors use pistons driven by a crankshaft and crankshaft can be driven by electric motors or internal combustion engines.

Diaphragm compressors
A diaphragm compressor (also known as a membrane compressor) is a conventional reciprocating compressor. The compression of gas occurs by the movement of a flexible membrane instead of an intake element.

Rotary screw compressors
Rotary screw compressors use two meshed rotating positive-displacement helical screws to force the gas into a smaller space

Rotary vane compressors
A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity.

Scroll compressors:
A scroll compressor, also known as scroll pump uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases They operate more smoothly, quietly, and reliably than other types of compressors .
