UNITED AIR FILTER S138D0021 AIR OIL SEPARATOR ELEMENT REPLACEMENT PART

Description:

The United Air Filter S138D0021 Air-Oil Separator Element is used in rotary screw air compressor systems to efficiently separate compressor lubricant from the compressed air stream before discharge. Commonly installed in industrial air compressors, manufacturing facilities, pneumatic systems, and process equipment requiring clean compressed air and effective oil recovery. Maintenance teams and compressor technicians use this part for repair, retrofit, expansion, or replacement of existing air-oil separator elements to maintain compressor efficiency and minimize oil carryover.

Applications:

The United Air Filter S138D0021 Air-Oil Separator Element is commonly used in rotary screw compressors, compressed air generation systems, industrial automation equipment, manufacturing plants, and pneumatic process applications. The separator removes oil aerosols from compressed air and returns recovered lubricant to the compressor system, helping reduce oil consumption, improve air quality, protect downstream equipment, and extend compressor service life in continuous-duty industrial environments.
