Abstract
A filter unit (12) or a cyclone unit (22) can alternately be attached to a cabin (2) to draw powder out of the cabin. The units move on wheels. In an operating position adjacent to the cabin (2), they are automatically aligned with flow connections and can be connected. A common fan (52) for both units is connected with the filter unit (12) via a compressed air cleaning device (42) in terms of flow, if the former is in the operating position, and at the same time it closes off the inlet to a post-filter unit (32), while when the filter unit (12) is removed and the cyclone unit (22) is in the operating position, this cyclone unit (22) is connected with the fan (52) via the post-filter (32), and the cyclone unit (22) closes off a flow inlet of the compressed air cleaning unit (42). In this way, color changes can be carried out in a short period of time, and good exhaust cleaning is achieved by the filter unit (12) during extended operation with the same color, without a color change.
