<p>A cabin (10) for spray coating objects with powdered material comprises at least one flat filter (22) and a cleaning device (7) which moves relative to the flat filter (22). To obtain a highly efficient cleaning system which can be used for all types of flat filter and which does not require the filter to be interchanged when the colour is changed, the rear face of the flat filter (22) is divided into a plurality of sealed, cell-like sections (72). The sections are associated with a compressed air nozzle (71) which is directed toward the filter, moves over the field of the sections (72) and acts on at least one of the sections.</p> |
