1624163309 Breather Filter Element Respirator Cartridge for Oil-Injected Screw Compressor

Product Introduction

Vent lines need filtering too, otherwise the cabinet breathes back its own mist. 1624163309 appears in parts catalogs as a breather/respirator filter element, tied to 1624163305 and 2901111500 kit references, used on oil-flooded screw compressor gearbox or casing breather assemblies . It catches oil mist and coarse contaminant at the vent path so the machine relieves pressure without drawing dirt in or fogging the surrounding bay.

A clogged breather shifts casing pressure, slows recovery after load changes, and can push oil past seals that were never meant to hold pressure. Swap it on service, not after it blocks. Check the housing, O-rings, and seat together—half a kit rarely seals properly.

Confirm element diameter, length, thread or collar style, and the host breather body before ordering; cross numbers vary between suppliers. Also called breather element, respirator filter, vent filter cartridge, gearbox breather insert.
