1613839700 Flanged Air Oil Separator Element for GA30 GA37 GA45 Screw Compressor

Product Introduction

Low oil carry-over starts and ends at the coalescing core, not at the drain valve. 1613839700 is an air oil separator element for oil-injected rotary screw compressors, cross-referenced as 2901056600, 1613839702, OT2075 and AS2468 in aftermarket listings, with GA30/GA37/GA45/GA50-class applications quoted by suppliers . Oil-laden discharge air enters the media, fine droplets merge, drain back through the scavenge path, and clean air continues downstream. Stable differential pressure protects dryers, valves, and pneumatic tools while keeping lubricant in the circuit.

Running it overdue is the hidden energy tax: DP climbs, oil consumption rises, and a loaded core can shed oil straight into the line . Replace on service hours or at the DP alarm, and check the return tube while the tank is open—blockage or a kinked scavenge line fakes a bad separator even with a fresh element.

Confirm flange hole pattern, OD, height, inner bore, and anti-static grounding against the removed cartridge. Dimensions and service-life figures vary between suppliers, so the old part and machine serial decide the final fit . Also called oil gas separator, coalescing separator cartridge, air oil separator filter.
