A housing has a peripheral wall provided with an opening in which a shaft is rotatably journalled with an end portion thereof extending through the opening to the exterior of the housing. Disc-shaped filter elements are mounted in axial succession on the shaft for rotation therewith. A sleeve surrounds the end portion of the shaft extending into the interior of the housing where it abuts against a terminal one of the filter elements. The sleeve is slidable axially of the shaft and a pressure-exerting arrangement is provided exteriorly of the housing for exerting pressure on the sleeve in a sense displacing it deeper into the housing and thereby exerting pressure upon and squeezing the filter elements on the shaft.
