2901021301 Heavy-Duty Flanged Air Oil Separator Kit for GA30 GA45 Screw Compressor

Product Introduction

Clean discharge air and controlled oil loss both come down to the coalescing core doing its job every hour. 2901021301 is listed by Atlas Copco as a separator kit for GA30-45 oil-injected screw compressors, with 2901-0213-01 and 1613688001 quoted as related references across supplier catalogs. Oil-laden compressed air hits the glass-fiber media, fine droplets coalesce, drain back through the scavenge path, and dry air continues downstream. Stable differential pressure protects dryers, valves, and pneumatic tools while keeping lubricant circulating in the circuit.

Running it overdue is a quiet energy tax: DP climbs, oil carry-over rises, lube consumption climbs, and a loaded core can shed oil straight into the line. Replace on service hours or at the separator differential alarm, and inspect the return tube while the tank is open—blockage or a kinked scavenge line fakes a bad separator even with a fresh kit installed.

Match flange pattern, OD, height, inner bore, and seal set to the removed element before dispatch. Service life quoted around 4000-8000h shifts with intake dust, oil condition, and operating temperature, so the old cartridge and machine serial stay the final fitment check. Also called oil gas separator, air oil separator element, coalescing separator cartridge.
