ABSTRACT:
In order to permit the passage of dust and coarse particles or only the former, and to allow continuous operation, a filter disk is arranged in a housing, in the air flow direction, so that it is rotatable to different operating positions. A diaphragm-like valve can be provided upstream of the filter disk, at the inlet of the air stream in the housing. The filter disk is arranged on an axle which is mounted in the filter housing and has an actuating element for rotation. In addition to the rotatable filter disk, an additional filter disk can be arranged a distance away, the additional filter disk being designed for fine filtration and being removably clamped between two parts of the housing parts.
