Kaeser SK26 compressor thumping.

by Wayne Brown


We have a Kaeser SK26 compressor. (F.Y.I. We had the air-end replaced last year.) The unit runs fine 24/7 but recently has started "thumping" at the end of each unload cycle. It sounds like someone stepping on the pedal of a bass drum. Any ideas what this may be?

Please advise.

Checked the intake/unload valve?
