The HITACHI 22114040 (U5A UNIT) air/oil separator replacement is precision-built to install exactly like the original. This aftermarket separator offers oil separation performance equal to or better than the original OEM separator specifications.
Oil in your air lines, rising oil consumption and climbing pressure drop are all signs it’s time to replace the air/oil separator. 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. Each separator is built to stay rigid under full operating pressure and maintain a steady pressure differential throughout its service life.
The HITACHI 22114040 (U5A UNIT) 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.
