The HYDROVANE HY59177 air/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.
Air/oil separators remove oil from compressed air before it leaves the compressor. This aftermarket separator captures fine oil aerosols and returns them to the sump, delivering the highest level of clean compressed air with minimum pressure loss. Our separators are tough enough to hold their shape under pressure and maintain even pressure differentials to avoid collapsing.
- 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 HYDROVANE HY59177 separator equivalent is built with superior materials and engineering. We have replaced oil separators from all major brands in hundreds of thousands of applications since 1976.
