®
An Oshkosh Corporation Company
lubricated unit powered by a gear-type aluminum hydraulic
motor through V-belts and a pulley.
Air is drawn in through dual oversized, dry-type air filters that
are located on the compressor pump to provide easy access
and long service life.
2.2.2 COOLING SYSTEM
Refer to
Figure 2-2
. The compressor cooling system
consists of a hydraulic oil cooler and a 12VDC electric
fan. It maintains a constant cooling air flow through the
unit to ensure that it does not exceed its specified
operating temperature limits.
Oil flows through the radiator type hydraulic cooler as
long as the hydraulic system is supplying oil to the
compressor, providing continuous cooling of the
hydraulic circuit.
The fan is mounted at the unit’s rear and draws air
through the package, directly cooling the compressor,
and providing cooling air for the oil cooler. The fan
operates continuously anytime power is applied.
2.2.3 ELECTRICAL SYSTEM
Refer to
Figure 2-3
. The control system’s automatic
START/STOP feature is controlled by air tank pressure,
but a manual ON/OFF is also included. Air pressure can
be adjusted up to 150 psig. Instrumentation gauges for
system pressure and operation hour accumulation are
located on the outside panel.
2.2.4 AIR CONTROL SYSTEM
When the compressor is ON, the control system
automatically starts and stops in order to maintain the
receiver tank pressure between 95 psig (minimum) and
175 psig (maximum).
A pressure switch relieves pressure in the cylinders when
the unit is unloaded.
2.2.5 HYDRAULIC CONTROL SYSTEM
The hydraulic motor is used to power the compressor
unit. If the proper flow and pressure is supplied to the
motor there should be many hours of trouble-free use in
conjunction with the compressor.
IMPORTANT
The compressor should not be operated
continuously at pressure settings above
150 psig.
