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.

QR-25

Our premium, top-of-the-line pressure lubricated piston air compressor is the QR-25. It’s a heavy-duty compressor that is pressure lubricated in all critical areas and delivers up to 25 hp. Available in single- and two-stage versions, the QR-25 is designed to operate at slower speeds and is equipped with intake loaders that minimize work. The rugged cast iron construction ensures a long life expectancy, less downtime and easier maintenance. Other key features include loadless starting, a manually reversible oil pump and rebuildable components. Seen as the industry standard in piston compressor technology, the performance of Quincy’s QR-25 is legendary.
