Operation
1. Both free moisture and solids are removed automatically by the
filter.
2. Manual drain filters must be drained regularly before the
separated moisture and oil reaches the bottom of the baffle or
end cap.
3. The filter element should be removed and replaced when
pressure differential across the filter is 69 kPa (10 psig).
Service Procedure
Caution: Shut off air supply and exhaust the pressure

may cause contamination, spotting, or migration of oil.

3. Clean all internal parts and bowl before reassembling.
4. The coalescing filter element should be removed and
replaced when pressure differential across the filter is 10
PSID. Differential gauges should be used to determine when
the maximum recommended pressure differential has been
reached.
