Patent number: 6964708Abstract: A booth for coating objects with powder, in particular for powder painting, comprises in a manner known per se a housing, in which there is situated at least one application device, with which powder can be applied to the objects. Situated in the upper region of the housing is an air plenum, which is fed with supply air via an inlet opening. The air plenum is closed off downwardly by a filter ceiling. In contrast to known filter ceilings, the one according to the invention is air-permeable in its marginal region only, while in its central region it consists of air-impermeable material. The supply air is thus introduced into the interior of the booth as a kind of “air curtain” which flows mainly along the side walls of the housing of the booth, entrains in the process stray excess powder which has not adhered to the objects to be coated, and supplies it to at least one extraction opening situated in the bottom of the booth.Type: GrantFiled: March 4, 2003Date of Patent: November 15, 2005Assignee: Eisenmann Maschinenbau KGInventors: Erwin Hihn, Wolfgang Bezner
