The ATLAS COPCO 2901-0099-01 filter 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.
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. Each separator is built to stay rigid under full operating pressure and maintain a steady pressure differential throughout its service life.
The ATLAS COPCO 2901-0099-01 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.
