The ATLAS COPCO 2255-3004-01 spin-on filter separator replacement is precision-built to install exactly like the original. This aftermarket spin-on air/oil separator offers oil separation performance equal to or better than the original OEM separator specifications.
Replacing the air/oil separator on schedule is one of the simplest ways to keep a compressor running clean and efficient. This replacement separator captures fine oil mist before it leaves the sump tank and returns it to the compressor, keeping your air clean and your lubricant where it belongs. Reinforced construction resists collapse, even as the media loads up toward the end of its service interval.
The ATLAS COPCO 2255-3004-01 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.
