The DONALDSON P52-5702 oil separator replacement is a direct drop-in replacement for the original OEM separator. This aftermarket air/oil separator offers oil separation performance equal to or better than the original OEM separator specifications.
Your compressor’s air/oil separator works hard every hour it runs, pulling oil mist out of the discharge air so it can be reused instead of carried downstream. A quality separator means less oil topping-off, less carryover reaching your dryers and filters, and lower energy costs from reduced pressure drop. Rugged construction keeps each separator from collapsing under high differential pressure.
The DONALDSON P52-5702 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.
