The separator strips the fine oil mist out of the compressed air leaving the oil tank, so the oil stays in the compressor and the air going to the line is clean. Every element is checked against the part number before it ships, and every order is covered by our

Will it fit my machine?
It replaces the element numbered Sullair 240158 and the other numbers in the cross reference table. Check the number on the old element or in the machine's parts list.
When should I change the element?
Change the separator at the hours in the compressor's service plan, usually together with the oil and the oil filter, and sooner if oil carry over or the separator pressure drop rises.
How do I fit it?
Stop the compressor and let all the pressure out of the oil tank. Remove the old element, clean the sealing faces, fit the new element with its new gaskets and tighten evenly. Run the compressor and check for leaks.
