  • Page 25 Operating Instructions Air/Oil Separator Filter During the process of air compression from pump, air and oil are mixed together to lubricate, seal and cool compressor rotors. This air and oil is transferred to air/ oil separator tank and then the air/oil separator filter removes oil mist from the compressed air.

  • Page 26: Operation

    Eaton Compressor Rotary Screw Compressor Refrigerated Dryer/Coalescing Filter (optional, not shown) The refrigerated dryer removes moisture content. The coalescing filter removes oil droplets and impurities in the compressed air. The refrigerated dyer/coalescing filter operates best with an automatic drain that removes water condensation collected during the airdrying process.
