The SULLAIR 5031 air-oil separator replacement is made with high-efficiency separation media and durable construction. This aftermarket separator offers oil separation performance equal to or better than the original OEM separator specifications.
Your compressor’s air/oil separator works hard every hour it runs, pulling oil mist out of the discharge air so it can be reused instead of carried downstream. A quality separator means less oil topping-off, less carryover reaching your dryers and filters, and lower energy costs from reduced pressure drop. Each separator is built to stay rigid under full operating pressure and maintain a steady pressure differential throughout its service life.
The SULLAIR 5031 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.
