Quincy Compressor QP Raciprocating Piston

General Information

Quincy Compressor QP Raciprocating Piston, Our family of reciprocating/piston air compressor products is well-suited for applications such as oil refineries, gas processing plants, refrigeration plants and many others. Options include pressure lubricated, splash lubricated, single stage and application-specific models. 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 steps where the air is compressed by a second, smaller piston to a pressure of up to 175 PSI.

QP 5-15 hp Industrial Duty Compressors

The Quincy QP series is designed for tougher 175 PSI applications where traditional splash lubrication just won’t measure up. The QP is a heavy-duty, cast-iron compressor that features an oil pump for pressure lubrication to the crankshaft, bearings and connecting rod up to the wrist pins. This advanced pressure lubricated system allows for a smoother, more continuous operation. Coupled with an attractive price, the QP balances cost effectiveness with longer life to maximize your investment.

Reciprocating Air Compressors Work

Compressors decrease the amount of space air takes up by compacting it. A reciprocating compressor is a positive-displacement air compressor that uses a crankshaft-powered piston and cylinders. Our piston air compressors use either a single- or two-stage process to compress air. 

Compressing air decreases its volume and increases its density without changing it to liquid. Here is how a reciprocating air compressor works: 

  1. Gas enters the cylinder through the intake valve. 
  2. The piston pulls away from the intake valve and allows the gas to pass into the cylinders. 
  3. The crankshaft powers the piston, which compresses the gas in one stroke of about 120 pounds per square inch (psi) of pressure. 
  4. In two-stage compressors, air travels to a second cylinder for another round of compression. A second piston compresses the gas at a pressure rate of 175 psi.
  5. Once complete, the compressed air is sent to a storage tank for use. 

Reciprocating air compressors are compact options workers can apply to natural gas processing and delivery and oil refining. These air compressors work across industries to give you powerful compression.
