Benefits at a glance…

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.

Intercoolers

• 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.
