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.
F
LUID MANAGEMENT SYSTEM
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.
M
OTOR/DRIVE SECTION
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.
