ABSTRACT:
The present invention relates to a filter cleaning device, preferably for the cleaning of gases, such as welding fumes. To provide a filter cleaning device which efficiently cleans the filter without need for dismounting it, the filter cleaning device comprises at least one rotary filter (10) with outwardly directed projections (17), and at least one impeding device (12) which upon rotation of the filter (10) causes the projections (17) to give way and permits them to revert, whereby a shaking movement is imparted to the projections (17) to make them shake off the impurities adhering to them and toss the impurities aside by the action of the rotation of the filter (10).
