An electrostatic powder coating installation which includes a cabinet accommodating a device for producing electrostatically charged powder, with a filter strip being disposed in the cabinet at a bottom end thereof. A first suction fan, covering a large portion of the bottom area of the cabinet is provided for producing a suction field in the cabinet with an underpressure by virtue of the provision of the filter strip. A cleaning apparatus or nozzle, associated with the filter strip, removes surplus powder lying on the filter strip. A device is provided for drawing the filter strip along at least one length of the cabinet when pigments in the powder change thereby assigning a specific zone of the filter strip to each pigment. A powder recovery installation includes a basic frame or housing which accommodates a powder container, a filter, a sifting machine, and a basket for the sifting material. The basket for the sifting material is adapted to be easily replaceable. A contaminant or dirt catching container is arranged so as to be at the same pressure level as the inner space of the powder container, with the container having a porous bottom. A suction conveyor with the nozzle enables the direct further processing of the powder and it is possible to provide a powder recovery installation which saves space and which is relatively inexpensive.
