The DONALDSON P52-5214 air-oil separator replacement is a cost-effective alternative to the expensive OEM separator. This aftermarket 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.
The DONALDSON P52-5214 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.
