The DONALDSON P04-0301 oil separator replacement is built with top-quality materials and workmanship. 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. Rugged construction keeps each separator from collapsing under high differential pressure.
The DONALDSON P04-0301 separator equivalent is built with superior materials and engineering. We have replaced air/oil separators from all major brands in hundreds of thousands of applications since 1976.
