290105600 Hydraulic / Lube Oil Filter Element For Atlas Screw Compressor Service

Product Introduction

Oil filters don’t look like a big ticket item until metal shavings and oxidized sludge start circulating through the airend and gearset. 290105600 (also seen as 290105600-3 / “filter element” in parts lists) is the filter element used in Atlas Copco compressor oil/lubrication or hydraulic filtration circuits, intended to trap wear particles, carbonized lube debris, and contaminant before they recirculate into the pump, bearings, rotors, and control lines. A clean element keeps oil flow stable, maintains film strength, and reduces the chance that fine grit turns the lube into lapping compound.

A clogged element rarely fails with a bang—it raises pressure drop across the filter, starves flow at cold start or high load, and can force bypass operation if fitted with a bypass; then dirt rides straight through. Replace on service hours or at the pressure-drop/condition signal, and pair it with the correct seal/O-ring from the service kit where applicable. Cutting intervals short makes sense in dusty sites, after a top-end/gear repair, or when oil analysis shows rising silicon/iron.

Fitting notes: relieve system pressure and drain to near ambient, clean the housing and sealing face, discard old gasket/O-ring, seat the new element squarely without prying the end cap, and torque/lock the cover per procedure. Confirm model/serial and compare OD/ID/length/seal style against the removed part—catalog photos vary and “filter element” covers several variants. Also called oil filter element, lube filter, hydraulic filter cartridge, line filter element,
