Kaeser Air/Oil Separator Replacement – 6.3789.0

The Kaeser 6.3789.0 Air/Oil Separator is a high-performance filtration component designed for Kaeser screw air compressors. It separates oil mist and oil particles from compressed air after the compression process, allowing clean compressed air to flow while returning separated oil back into the compressor oil circuit.

This separator uses advanced coalescing filtration technology to reduce oil carryover, maintain efficient compressor operation, and protect downstream air treatment equipment. A properly functioning air/oil separator helps maintain air quality, reduce oil consumption, lower pressure losses, and improve overall compressor reliability.

Product Details
