Compressors are similar to pump‚ both increase the pressure on a fluid and both can transport 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. Types of compressors The main types of compressors are shown below: Compressor types Positive displacement Dynamic 1. Reciprocating. 2. Rotary 1.Centrifugal. 2. Axial
