The idea of reciprocation, that refers to moving something forward and backward, underlies the operation of reciprocating air compressors. These devices, also referred to as piston compressors, are positive displacement machinery, which means that they increase air pressure in order to compress it. Choosing the best model for your application, whether you're a home craftsperson or in charge of a manufacturing floor, requires a thorough understanding of reciprocating compressor design, manufacturers, and the working principles of the other available types.
