pressed air collects on the surface of the separator ele-
ment as the compressed air flows through the separator.
As more fluid collect
s on the element surface, it then
flows to the bottom of the separator. A return line (or
scavenge tube) leads from the bottom of the separator
element to the inlet region of the compressor unit. Fluid
collecting on the bottom of the separator element is
returned to the compressor by the pressure difference
between the area surrounding the separator element and
the compressor inlet. An orifice (protected by a strainer)
is included in this return line to assure proper and unob-
structed flow. The receiver tank is code rated at 200 psig
(1
3.8 ba
r) working pressure. A minimum pressure device
located do
wnstream from the separator, ensures a mini-
mum receiver pressure of 80 psig (5.5 bar) during all
condition
s. Keeping this pressure level stable is neces-
sary for proper air/fluid separation and proper fluid circu-
lation. A pressure relief valve (located on the wet side of
the
sepa
rator) is set to open if the sump pressure
exceeds 200 psig (13.8 bar).

WARNING
Do not remove caps, plugs and/or other compo-
nents when the compressor is running or pres-
surized. Stop the compressor and relieve all
internal pr
essure by following proper lockout/
tagout procedures before removing these items.
