A device for collecting parts of sediment dust and partly dust suspended in the air comprising a motor-driven fan (1), that on its sucking side is connected to a first air duct (10) containing two air filters connected in a series (2, 4). Collection of sediment dust occurs through the air transport in the above named first air duct (10). Collection of suspended dust occurs through a second air duct (14), which through an adjustable connection (19) is connected to the first duct (10) between both filters (2, 4).<IMAGE> |
