A sudden drop of zero pressure differential or sudden heavy oil carryover may
indicate a ruptured element.
Inspection - After removal of separator element, shine a light inside the element to reveal areas of heavy
dirt or varnish deposits or breaks (ruptures) in element media.
Removal of Oil Separator For Inspection or Replacement:
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
