Abstract: A cabin for spray coating objects with powdered material has flat filter surfaces and a cleaning device that moves relative thereto. The rear face of the filter is divided into a plurality of individual cell shaped sections sealed with respect to one another. A nozzle directs air from the rear face of the filter toward the interior of the cabin to dislodge powdery material from the filter's inner surface. The nozzle moves across the field of cell shaped sections supplying compressed air to at least one of the sections at a time during the cleaning cycle.
