A Compressor is a mechanically operated machine that is used in many applications, most of which involves the pressing the gas or air into less space (increasing the pressure) for the transports and storages in petroleum refineries and chemical plants. Compressors are classified in many ways out of which the common one is the classification based on the principle of operation: Positive Displacement and Rotodynamic (Centrifugal and Axial) Compressors. The Positive displacement compressors can be further divided into Reciprocating and Rotary (Screw) Compressors.
Reference Definition by Wikipedia: A Compressor is a machinery equipment to increase a pressure of gas used for transferring gases and a pressurisation for a storage and transportation (increasing pressure with decreasing volume), and other purposes. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids.
