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.

Powder spray coating system with the following characteristics: a cabin (2, 2/2), through which objects 4 which are coated with powder in the cabin are transported, and which has a powder/air exhaust opening (10) essentially opposite a spray device (104, 108); a mobile first filter unit (12), which
Powder spray coating system with the following characteristics: a cabin (2, 2/2), through which objects 4 which are coated with powder in the cabin are transported, and which has a powder/air exhaust opening (10) essentially opposite a spray device (104, 108); a mobile first filter unit (12), which has a flow inlet (14) and a flow outlet (16) and at least one filter element (18) for powder in the flow path between them; a mobile cyclone unit (22), which has a flow inlet (24) and a flow outlet (26) and a plurality of small cyclones (28) through which parallel flow occurs, for separation of powder, in the flow path between them; a post-filter unit (32) arranged close to the cabin (2) next to it, which has a flow inlet (34) and a flow outlet (36) and at least one filter element (38) for post-filtering the powder/air stream pre-filtered by the cyclone unit (22), in the flow path between them; a compressed air cleaning unit (42) arranged on the cabin (2, 2/2) above the exhaust opening (10) on the outside of the cabin, which has a flow path (48) with a flow inlet (44) and a flow outlet (46) and a device (50) for occasional generation of compressed air bursts, which it blows into the filter elements (18) of the first filter unit (12), counter to the flow direction of the flow path (48), (into these filter elements 18), to clean these filter elements (18); a fan (52), the suction intake (54) of which is arranged close to the flow outlet (36) of the post-filter unit (32) and close to the flow outlet (46) of the compressed air cleaning unit (42) and is connected with both outlets (36, 46) simultaneously, in terms of flow; a part (60) of the first filter unit (.12) forms a closure element to close the flow inlet (34) of the post-filter unit (32); a part (63) of the cyclone unit (22) forms a closure element to close the flow inlet (44) of the compressed air cleaning unit (42); the first filter unit (12) and the cyclone unit (22) can alternatively be moved under the compressed air cleaning unit (42) on wheels, to bring them into an operating position in which the flow inlet (14) of the first filter unit (12) or the flow inlet (24) of the cyclone unit (22) is adjacent to the exhaust opening (10) of the cabin (2, 2/2) and is connected with the interior (70) via the exhaust opening (10), in terms of flow; the flow inlet (44) of the compressed air cleaning unit (42) and the flow inlet (34) of the post-filter unit (32) are fixed in place in such a way that only if a) the first filter unit (12) was brought into the operating position will its flow outlet (16) align with the flow inlet (44) of the compressed air cleaning unit (42) and only then can these be connected, and at the same time, its closure element (60) aligns with the flow inlet (34) of the post-filter unit (32) and can close this flow inlet, b) the cyclone unit (22) was brought into the operating position will its flow outlet (26) align with the flow inlet (34) of the post-filter unit (32) and only then can these be connected, and at the same time, its closure element (63) aligns with the flow inlet (44) of the compressed air cleaning unit (42) and can close this flow inlet, while the first filter unit (12) and the cyclone unit (22), when they are moved away from the operating position, at the same time are also moved away from the flow inlet (34) of the post-filter unit (32) and the flow inlet (44) of the compressed air cleaning unit (42).
