Atlas Copco 2901990098 Air Oil Separator Element

The Atlas Copco 2901990098 is an air/oil separator element designed for oil-injected screw air compressors. It functions to separate oil mist from compressed air discharge, ensuring clean air output and oil return to the lubrication circuit. The separator utilizes a folding microporous filter media structure achieving a filtration precision of 0.01 micron. It maintains an initial pressure differential below 0.02 MPa and limits oil carryover to less than 3 ppm. Rated service life ranges between 3,500 and 6,000 operating hours under standard conditions. This part serves as the core component of the OSE/Scavenge Line Kit for the GA VSD+ series. Cross-reference interchange includes OCP OS151-074 and Fluitek FLK16-12271. Associated Atlas Copco part numbers include 1630170801 and 1649800141. Direct fitment applies to Atlas Copco GA75L VSD+, GA90 VSD+, GA110 VSD+, GA75 VSD, and C142 VSD+ compressor models.
