are necessary. Accumulated sludge
and moisture should be drained off.
Sediment should not be permitted to
fill above the lower baffle.
Wash filter element at intervals with
naphtha to maintain filtering efficiency.
To clean element, depressurize system,
unscrew metal bowl, and unscrew
element from head. Dry filter element
thoroughly before reassembling. Clean
filter bowl(s) only with soapy water.

Inspect O-ring, replacing if damaged
or distorted. Reassemble with care to
avoid stripping threads on bowl. After
a metal bowl with sight is tightened, it
may be rotated up to 180° for proper
viewing.
COALESCER
If the filter is installed properly, it should
give long trouble-free service. The
pressure drop across the filter should
not exceed 10 psi. If the pressure drop
exceeds 10 psi, either the filter ele -
ment needs to be replaced or the unit is
being operated beyond its capacity and
Filter

a larger size unit is required. Operating
the filter at a pressure drop in excess of
10 psi will greatly reduce the efficiency
of the filter.
If oil appears downstream:
1. Check downstream air lines to be
sure that they are free of residual oil.
2. Check to see that the filter element
and O-ring are in good condition
and installed properly.
DIFFERENTIAL PRESSURE INDICATOR
When the filter is depressurized,
periodically clean and grease the piston
O-ring with a non-silicon ring grease.
