The BAUER GROUP R-228 separator replacement installs as a direct drop-in for the original OEM separator. It measures 4.44″ OD x 13.38″ tall with a 2.64″ ID. 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
This BAUER GROUP R-228 separator equivalent is manufactured to the highest quality standards and is guaranteed. Since 1976, we have replaced air/oil separators from all major brands in hundreds of thousands of applications.
