A Reciprocating/Piston 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.
Quincy piston air compressors are well-suited for various applications such as oil refineries, gas processing plants, refrigeration and industrial plants, etc. with options that include pressure lubricated, splash lubricated, single stage and application-specific models.

A Proud Legacy of Excellence/strong>
The modern-day Quincy QR-25 traces its roots to the 1930s when it was introduced as a member of what was simply known as “the Quincy Line.” A portable QR-25 version was introduced during the 1950s and was used to provide heated compressed air to keep lenses clear on military equipment. The first four-cylinder QR-25 was unveiled during the 1960s and the Coast Guard began using the QR-25 as part of its tug boat starting procedures in the 1970s.
