ABSTRACT:
A device for recovering powder, in particular from powder-spray housings, includes a filter unit mounted in a separate housing, which unit has at least one filter element mounted between the crude gas side and the pure gas side thereof. The pure gas side is coupled to an exhaust and a cleaning device is provided for the filter element for a continuous removal of the drawn-in powder. The filter element is moveable along a pure gas channel as an endless filter band fed around a drive roller and a tension roller. The band has opposed band portions which form the separation between the crude gas side and the pure gas side and which are subjected to a subsequent cleaning device.
