Compressed Air-Oil Separation

Compressed Air-Oil Separation

Functions
As one of three key filters for screw compressors, it separates oil mist from compressed air, recycles most lubricant back to the main machine and keeps residual outlet oil ≤3ppm to protect downstream equipment.
Construction
Consists of multi-layer glass fiber filter media, galvanized support mesh, sealing gaskets and oil return capillary for oil reflux.

    • Description

    Oil-Gas Separator Filter for Air Compressor


    Working Principle
    Big oil drops sink by gravity first; fine oil mist is captured and condensed on fiber layers, then recycled, with dry clean air discharged centrally.

    Types

    1.Built-in type: inside oil-gas tank for regular screw compressors;
    2.External type: outside tank for large low-pressure units.

    Service Life

    2000–4000 working hours normally; ~1500 hours under dusty/high-temperature harsh conditions.
    Replace when air carries excess oil, fuel consumption surges or overheat alarm triggers.
    Risks of Poor-Quality Products
    Excessive air oil content damages pneumatic tools; blocked oil return causes main unit abrasion or seizure; fallen filter scraps clog pipelines.
