The HITACHI OSP 37S5A oil separator replacement is a direct drop-in replacement for the original OEM separator. 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. Reinforced construction resists collapse, even as the media loads up toward the end of its service interval.
The HITACHI OSP 37S5A 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.
