Abstract
An apparatus for cleaning air charged with contaminants, especially fibers and dust, comprising a pre-separator and a dust filter arranged after the pre-separator. At least one movable suction nozzle is effective at the surface of the dust filter. The pre-separator, constructed as a body of rotation, possesses an inlet portion structured for producing a spin flow and a jacket portion structured as a sieve surface which is surrounded by a rotatably mounted filter drum of the dust filter. A cylindrical filter body of the filter drum has operatively associated therewith at the inner surface thereof the movable suction nozzle, and drive means are operatively connected with the suction nozzle and filter drum.
