Scheduled compressor service
Change the separator at the interval on the compressor's maintenance schedule (on most Kaeser screw compressors every 3,000 to 6,000 running hours, or every two years), and sooner if oil carry-over rises or the separator pressure drop gets high.
Breakdown spares
Keep one on the shelf so a blocked air/oil separator element does not leave a Kaeser compressor standing while parts are ordered.
Workshop and fleet stock
Hire fleets and workshops servicing several Kaeser compressors can stock the element by its part number.
No. It is an aftermarket air/oil separator element made to replace the Kaeser 6.3672.0. It is not made by or affiliated with Kaeser, and the part number is used only to show what it replaces.
It replaces the element numbered 6.3672.0 (also written 636720) on Kaeser SK rotary screw compressors. Check the number on the old element or in the compressor's parts list, or measure it: this one is 128 mm (5.04 in) across the flange, 100 mm across the body, 40 mm inside and 170 mm (6.69 in) high.
Change the separator at the interval on the compressor's maintenance schedule (on most Kaeser screw compressors every 3,000 to 6,000 running hours, or every two years), and sooner if oil carry-over rises or the separator pressure drop gets high.
Stop the compressor and let all the pressure out of the oil tank. Take the cover off the separator tank, lift out the old element and clean both sealing faces. Fit the new element with new gaskets, keep the earthing staple in place against the gasket, refit the cover and tighten the bolts evenly in a cross pattern. Run the compressor and check for leaks.
