Air Oil Separator Element UNITED AIR FILTER S138D0298 Clearance 2025

The UNITED AIR FILTER S138D0298 is a key component of your lubricated rotary screw air compressor. The oil is injected with the intake air to seal the compressors screws with the chamber, lubricate bearings and remove heat of compression from the machine, after the air and oil mix is compressed by the screw a separator will filter the mix to reinject the oil into the compression chamber and send the air downstream.
The air oil separator tank normally has a preliminary mechanical separator to remove most of the liquid oil, the element function is to capture the mist created by the flow and velocity of the mix getting into the tank.
The top-hat style air oil separators are installed inside a separator tanks with a gasket and a grounding wire. They normally need to be changed anywhere between 4000 hr and 8000 hr depending on the parts.
