the replaceable fluid filter element. This replaceable
filter element contains a built-in bypass valve. Under
conditions of restricted flow through the element, the
bypass valve helps ensure adequate compressor
fluid flow, as well as helps prevent element failure.

LUID ANAGEMENT YSTEM
The fluid management system consists of a
multichambered primary/secondary separator, the
final air/fluid separator element, cooler bypass group
and fluid filter.
As compressed air/fluid enters the sump, the first
fluid separation takes place due to a reduction of flow
speed coupled with a change of direction of the flow
within the sump housing. Then the compressed air
reaches the separator, where the finest fluid drops
and mist are separated.

OTOR RIVE ECTION
The motor/drive section consists of a squirrel cage
induction motor and integrated drive gearing which is
separated from the motor by a replaceable shaft
seal.
The minimum pressure/discharge check valve is
mounted on the compressor drive housing. Its
functions are as follows:
1. Maintain a minimum sump pressure of 60
psig (4.1 bar) under full load operation to
help assure adequate fluid pressure.
2. Act as a check valve to isolate the compres-
sor from the system at shutdown or unload.
