An Oshkosh Corporation Company
The compressor is now operating automatically. It will
continue to pump until the pressure reaches 150 psig
(factory set-point). At this point the compressor unit will
switch off and the hydraulic flow will be redirected back to
the supply tank; any air in the compressor will be vented
to the atmosphere. The accumulated pressure in the
receiver tank is maintained by the check valve fitted to
the compressor outlet connection.
When a demand is applied to the unit, the receiver tank
pressure drops until it reaches the low pressure set-point.
The compressor then automatically restarts and repeats
this cycle in response to service demands and receiver
tank pressure.
