Reciprocating Air Compressors
The reciprocating air compressor, also known as a piston compressor, delivers air at high pressure using positive displacement. Oil refineries, chemical plants, natural gas processing, and gas pipelines use reciprocating air compressors because they are safe and reliable compressed air systems. The reciprocating air compressor is more common for discontinuous compressor use while the rotary screw air compressors are built for continuous applications.
