Products Description
Factory 88291006 940 Air Oil Separator Screw Compressor Filter.The oil separation filter element is a core precision filtration component used in oil-injected screw compressors and vacuum pump systems to achieve effective oil‑air separation. Its primary function is to efficiently intercept and recover entrained lubricating oil from compressed air, reducing the outlet oil content to an extremely low level, thereby protecting downstream equipment and meeting process requirements for air purity.
Manufactured with multi‑layer ultra‑fine glass fiber or high‑performance synthetic fiber media, the filter element offers high filtration accuracy and low flow resistance. It maintains stable separation efficiency across a wide temperature and pressure range, typically limiting outlet oil content to below 3 ppm. The compact design ensures low pressure drop and economical energy consumption, while the filter media exhibits excellent heat resistance and corrosion resistance, making it suitable for prolonged continuous operation in industrial environments. The element is also equipped with built‑in oil return or drain features, facilitating routine inspection and replacement.Factory 88291006 940 Air Oil Separator Screw Compressor Filter.

Applications
Oil-injected screw air compressors
Vane compressors and vacuum pumps
Oil recovery systems
General industrial manufacturing, automotive painting, electronics, pharmaceuticals, food packaging, and other sectors requiring high-quality compressed air.
Why this matters: Accumulated static discharge can cause sparking – which is not only a safety hazard but can also burn through the filter media.
Groove Treatment
The groove on our flange is a specially designed limiting counterbore. It is not for holding a gasket - rather, it is designed to prevent the gasket from being crushed or deformed when you tighten the bolts. This ensures long-term, leak-free operation of your machine, and the seal lasts much longer than a standard flat flange.

FAQ
1. Q: How do I know when the oil separation filter element needs replacement?
A: The primary indicator is the pressure differential across the element. When it reaches 0.08–0.10 MPa, the element is significantly clogged and should be replaced promptly. Additionally, increased oil carryover in the outlet air or abnormal rises in operating current also signal performance degradation.
2. Q: Can oil separation filter elements from different brands be used interchangeably?
A: Yes, as long as the interface dimensions, mounting style, filtration rating, and seal material are compatible, and the element meets the original equipment's pressure and temperature requirements. We offer standard models compatible with all major compressor brands.
3. Q: Is higher filtration precision always better?
A: Not necessarily. Precision should match system requirements. Over‑specifying precision increases pressure drop and energy consumption while shortening service life. In most industrial applications, maintaining outlet oil content below 3 ppm is sufficient.
4. Q: What factors affect the service life of the filter element?
A: Key factors include inlet air temperature, lubricant quality, working pressure, ambient dust concentration, and overall equipment maintenance. High temperatures and poor‑quality oil accelerate media aging, while dust speeds up clogging.
