The WORTHINGTON 43109 air/oil separator replacement is built with top-quality materials and workmanship. This aftermarket 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. Reinforced construction resists collapse, even as the media loads up toward the end of its service interval.
The WORTHINGTON 43109 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.
