Oil separator element life cannot be predicted; it will vary greatly depending on the conditions of
operation, the quality of the oil used and the maintenance of the oil and air filters. The condition of the
separator can be determined by pressure differential gauging or by inspection.
Pressure Differential Gauging - The "CHANGE SEPARATOR" advisory will flash when the pressure
differential across the oil separator reaches approximately .55 bar. Replace the oil separator element at
this time. If ignored, the unit will shut down and the advisory will illuminate steadily when the pressure
differential reaches 1 bar.
Using an oil separator element at excessive pressure differential can cause
damage to equipment. Replace the separator when the "Change Separator"
advisory appears.
A sudden drop of zero pressure differential or sudden heavy oil carryover may
indicate a ruptured element.
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
and filters.
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 the element media.
