Reciprocating Compressors

A reciprocating compressor is a positive displacement compressor that uses a crankshaft-driven piston and cylinder to compress the air. A single-stage reciprocating air 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 1-25 hp Reciprocating Compressor

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.

Features:

  • 1-25 hp
  • 3-95 acfm, 20-500 psig intermittent
  • Single & Two Stage
  • Cast iron full pressure lubricated
  • 5-Year limited warranty

QT 3-15 hp Two Stage Reciprocating Compressor

Our two-stage splash lubricated QT piston air compressor models are designed to deliver higher volumes of air while also consuming less energy. The special valve design provides the highest possible volumetric efficiency and features super-strong stainless steel valves. The balanced counter-weighted crankshaft ensures smooth operation and fewer maintenance headaches. The cast iron construction also assures a long compressor lifespan. As with our QP line, the QT is available in Pro Unit and Max Unit options.

Features:

  • 5-15 hp
