The DONALDSON P52-5709 air/oil separator replacement is precision-built to install exactly like the original. This aftermarket 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. Built to hold up to the pressure and heat inside the sump tank, our separators maintain even pressure differentials without deforming.
- 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
The DONALDSON P52-5709 separator equivalent is manufactured in the USA with superior materials and engineering. We have replaced air/oil separators from all major brands in hundreds of thousands of applications since 1976.
