Cooler operating temperatures
result in longer life and consistent
performance over time.
Gasket less design eliminates the
possibility of blown head gaskets
for trouble-free operation.
Aluminum alloy first-stage piston
and cast iron second-stage piston
ensure proper balance.
Two high efficient lap joint
compression rings with
bi-directional seal provide the
most efficient air delivery.
High-density, die-cast aluminum
alloy rods minimize reciprocating
weight. An integral, precision bored crankpin bearing and
needle bearing for the wrist pin
minimize friction and properly
distribute loads for extremely
Pressure Relief Valves
Located in interstage and
Rugged cast iron oil reservoir
has convenient sight gauge glass,
corner oil fill boss and large oil
Large diameter finned tubing is
positioned to obtain the greatest
cooling effect between stages for
maximum compressor efficiency.
Optimized Cooling Fan/
Precision balanced flywheel
has fan blades for optimum
compressor cooling and life.
Single-unit, disc-type valves
provide low lift and long life. Discs
are made of corrosion resistant
steel, valves are easily serviced by
removing the manifolds.
Oversized Main Bearings
Tapered roller-type main bearings
provide full contact and support
of the crankshaft plus deliver the
longest possible life.
Constructed of rugged ductile
iron with large diameter throws
for minimum bearing loads and
large counterweights to minimize
Load less Starting
centrifugal unloader assures
longer motor life by allowing the
compressor to start unloaded
