Loadless Starting 

Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.

Optional Equipment

Many options are available to help you develop a Gardner Denver compressor package that exactly matches your specific operating requirements.

  • Magnetic Starter
  • Air-Cooled or Water-Cooled Aftercooler
  • Automatic Tank Drain (Pneumatic)
  • Vibration Isolators
  • Low Oil Level Monitor
  • Refrigerated Dryer
  • Microprocessed Duplex Relay Control Panel
  • AEON™ Lubricants
  • Power Monitor
  • Constant Speed Control
  • Dual Control to run either in start/stop or constant speed mode
  • NEMA 4 rated parts
  • Alternate Voltages and TEFC, ODPHE, TEFCHE Electric


Multi-Finned Cylinders

  • Cooler operating temperatures result in longer life and consistent performance over time.

Integral Cylinder/Head

  • Gasketless design eliminates the possibility of blown head gaskets for leak-free operation.

Balanced Pistons

  • Aluminum alloy first-stage piston is weight matched to the cast iron second-stage piston, ensuring proper balance.

Piston Rings

  • Three compression rings and one oil control ring provide excellent oil control, minimum blow-by and high efficiency air delivery.

Lightweight Connection Rods

  • High-density, die-cast aluminum alloy rods minimize reciprocating weight. An integral, precision-bored crankpin bearing and a needle bearing for the piston pin properly distribute bearing loads for longer bearing life than bushings.

Pressure Relief Valves

  • Located in interstage and discharge.


  • Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency.

Optimized Cooling Fan/Flywheel

  • Precision balanced flywheel has fan blades for optimum compressor cooling and life.

Reliable, High-Flow Valves

  • Single-unit, disc-type valves provide low lift and long life. Discs are made of corrosion resistant Swedish steel. Valves are easily serviced by removing the manifolds only.

Oversized Main Bearings

  • Tapered roller-type main bearings provide full contact and support of the crank plus delivers the longest possible life.

Balanced Crankshaft

  • Constructed of rugged ductile iron with large diameter throws for minimum bearing loads and counterweights to minimize vibration.

Large Capacity Crankcase

  • Rugged cast iron oil reservoir has convenient sight gauge glass, corner oil fill boss and large oil drain.
