The 1092300919 air oil separator is a high-performance coalescing filter element designed for Atlas Copco GA55, GA55+, GA55VSD, GA75, GA75+, GA75VSD, GA90, GA90VSD oil-injected screw air compressors. It is the core component for separating oil mist from compressed air, ensuring clean, dry, oil-free air output while recycling lubricating oil back to the compressor system.
This replacement element matches OEM specifications in filtration efficiency, pressure drop, and service life, providing a cost-effective alternative to genuine parts without compromising performance.

Installation & Maintenance Tips
- Installation: Replace with the compressor powered off and depressurized; ensure proper sealing of gaskets/O-rings; connect the oil return line correctly.
- Maintenance: Monitor differential pressure; replace when ΔP reaches 0.08–0.1 MPa or at 4,000-hour intervals (whichever comes first); avoid using low-quality oil to prevent premature clogging.
