Pressure Lubricated Reciprocating/Piston Air Compressors
A reciprocating air compressor is a positive displacement compressor that uses a crankshaft-driven piston and cylinder to compress the air. A single-stage reciprocating piston compressor works by drawing the air into the cylinder where it is compressed in a single piston stroke of approximately 120 PSI and then sent to a storage tank. A two-stage compressor includes an additional step where the air is compressed by a second, smaller piston to a pressure of up to 175 PSI.
