What is a reciprocating air compressor?
Reciprocating air compressors (also known as Piston air compressors) are positive-displacement compressors that employ a crankshaft-driven piston and cylinder to compress the air. Successive volumes of air are confined within a sealed space.
What is the difference between a piston and a rotary compressor?
A piston air compressor is oil-cooled, which results in the discharge of oil residue when the compressed air is discharged. Whereas rotary air compressors are usually equipped with two interlocking helical rotors fit with a little gap between them and soaked in an oil bath inside a housing.
What are compressor pistons constructed of?
