The CAMPBELL HAUSFELD IS041000AV filter separator replacement is a direct drop-in replacement for the original OEM oil separator. This aftermarket air/oil separator offers oil separation performance equal to or better than the original OEM separator specifications.
In an oil-flooded rotary compressor, the air/oil separator strips lubricating oil from the discharge air before it leaves the sump tank and sends it back to the compressor. A healthy separator keeps oil carryover low, protects downstream dryers and filters, and reduces oil top-offs. Each separator is built to stay rigid under full operating pressure and maintain a steady pressure differential throughout its service life.
- 2 – 3 PPM residual oil content in functioning systems
- Every air/oil separator is individually tested for electrical ground
- Borosilicate Microglass filter media is standard
- Top-quality gasket material
