The DONALDSON P52-5707 oil separator replacement is designed for long service life and low pressure drop. This aftermarket air/oil separator offers oil separation performance equal to or better than the original OEM separator specifications.
Every oil-flooded compressor depends on its air/oil separator to keep lubricant in the system and out of the air line. This separator captures fine oil mist in the sump tank and drains it back to the compressor, delivering clean air with minimal pressure drop. Our separators hold their shape under pressure and maintain even pressure differentials, preventing collapse.
- 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 P52-5707 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.
