An air compressor is an apparatus for compressing a gas. The air compressor is similar to the water pump construction. Most air compressors are reciprocating piston type, rotating blade or rotating screw centrifugal compressor is a very large application program.
Air compressor is the main body of gas source device. It is the device that converts the mechanical energy of prime mover (usually motor) into gas pressure energy, and it is the air pressure generating device of compressed air.
