Powerful Performance

The Quincy QT reciprocating piston air compressor is more than just your typical splash-lubricated two-stage. The highly efficient, robust QT delivers more air (CFM) per brake horsepower while consuming less energy. We use cast-iron, which is needed for strength, durability, and aluminum, which is needed for optimum cooling and long life. A Quincy compressor may cost you a little more upfront, but the long-lasting performance will save you money over time.

The Quincy QT series is designed for maximum productivity and efficiency; it is the reliable choice for light industrial and commercial applications. The heavy-duty cast-iron construction and quality components make it more than a match for tough working conditions. The aluminum head dissipates heat to ensure the compressor runs as cool as possible, while the Quincy valve design provides the highest volumetric efficiency. Leading the industry with the most CFM per brake horsepower, the Quincy  delivers more air and consumes less energy.

What Makes It A Quincy?

Compressor Head, Gaskets, and Valves

  • Aluminum head for cooler operating temperatures and longer life.
  • Graphite cylinder and head gaskets for positive sealing and improved performance.
  • Stainless-steel, corrosion resistant reed valves with controlled lift for maximum efficiency.

Interstage Intercooler

  • Finned-copper-tubed intercooler dissipates excess heat from the first stage of compression to the second-stage, helping to eliminate carbon build up in the head and increase valve life.


  • Large, balanced cast-iron flywheel for smoother operation, angled for maximum cooling across the compressor for longer life.


  • High performance, automotive-style rings allow less than 6 PPM oil carryover.


  • Balanced counter-weighted crankshaft for smooth, trouble-free operation.


  • Cast-iron cylinder, flywheel, and crankcase for dependability.
  • The extra-capacity oil reservoir assures low oil temperatures for lasting performance.


Superior Components

Quincy packs a one-two punch when comparing components to lower priced compressors. We feature IEC magnetic starters, premium motors, high quality pressure switches, metal automotive style filter/silencers, and a manual ball valve-style tank drain.
