1613901400 Coalescing Oil Mist Trap Cartridge for Small Frame Screw Compressor

Product Introduction

Oil mist that escapes the tank ends up in your air line, your dryer, and your tools. 1613901400 matches the visual profile of a compact, flanged air oil separator element shown here, featuring a scalloped/lobed top flange, white wrap-style coalescing media body, central inner mesh, and accompanying O-rings for sealed installation. Applied on small frame oil-injected screw compressors (GA5/GA7/GA11C-class), fine glass-fiber media pulls suspended oil droplets from discharge air; droplets grow, drain via the scavenge path back to the lube circuit, and clean air passes through.

Let differential pressure set the change interval, not guesswork. As the element loads, DP climbs, oil carry-over rises, and the compressor burns extra power pushing air through it. Inspect the return line while the separator housing is open—a blocked or misrouted scavenge tube mimics a bad separator even when the new core is fine. The included gaskets must seat cleanly against the flange; reused seals and uneven bolt torque remain the top cause of post-installation leaks.

Confirm flange lobe pattern, OD, height, inner bore, and seal style against the removed element before dispatch. Cross references (2901052300) and service life quoted around 3500–5200h shift with intake dust, oil condition, and operating temperature, so the old cartridge remains the final fitment check. Also called oil gas separator, air oil separator element, coalescing separator cartridge.
