Abstract: A colour change system for a powder coating facility comprises a plurality of containers 24a-24e each with a different colour powders; a conduit for conveying powder from one of the containers 24a-24e to a coating applicator 12; a suction unit 18 connected to the conduit and having an end-piece with a powder-drawing inlet opening; a cleaning unit 34; a translation mechanism for moving the end-piece; and a controller. The containers 24a-24e and the cleaning unit 34 each have an opening 25 for receiving the end piece. The controller effects a change of powder colour by controlling the translation mechanism to extract the end-piece from a first container 24d, to move it to the cleaning unit 34, and after cleaning to move the end piece to a second container 24e. The system allows automated cleaning between colour changes, which reduces operating downtime.
