The CUMMINS FILTRATION AS 2445 filter separator replacement is built to OEM form, fit and function using top-grade media. This aftermarket air/oil separator offers oil separation performance equal to or better than the original OEM separator specifications.
The air/oil separator is the last line of defense between the compressor’s lubricant and your compressed air system. By capturing oil mist and returning it to the sump, a quality separator lowers oil consumption, reduces carryover and helps the compressor run efficiently. Reinforced construction resists collapse, even as the media loads up toward the end of its service interval.
- 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
