Abstract

An installation for coating objects with powder, in particular for powder painting, comprises a booth which is known per se and in which powder can be applied to the objects by an application device. Stray powder is entrained by an air stream directed through the interior of the booth from the top downwards. The mixture of air and powder is extracted via an extraction opening in the bottom of the booth and supplied to a movable filter unit which is situated beneath the extraction opening and in which the powder is separated from the air/powder mixture for reuse. A plurality of such movable filter units are movable while suspended from a supporting-rail system, it being possible for all of these filter units, which are each intended for separating off a particular type of powder in particular one powder paint color, to be selectively brought under the extraction opening of the booth. On changing the powder used in the booth, the filter unit intended for the particular powder can thus be brought to the required position in a simple manner without complex maintenance work, while the filter unit used until then can be parked in a parking position on the supporting-rail system until the…
