1622035101 Spin-On Oil Separator Element for Screw Air Compressor

Product Introduction

Discharge air stays clean only if the separator catches every micron on the way out. 1622-0351-01 is identified as a spin-on oil separator (packaging marked 1622-0351-01), matching the cylindrical canister shown beside its box. In oil-injected rotary screw compressors, this spin-on assembly strips fine oil mist from the compressed air before it exits the air/oil receiver, protecting downstream lines and keeping lubricant circulating through the airend.

When this element starts to fail, symptoms escalate quickly: rising differential pressure, excessive oil carry-over into the air line, and climbing lube consumption. A clogged separator forces the compressor to work harder, driving up energy costs and risking blowdown issues. Installation demands a clean sealing face on the separator housing; lubricate the gasket slightly and hand-tighten—over-tightening crushes the seal and causes bypass. Run a post-service check to confirm no leaks and normal pressure drop.

Before buying, verify thread size, canister height, and outer diameter against the old unit; also referenced as 1622035101. Also called spin-on separator, air-oil separator, demister filter, oil mist trap.
