Claim:
Booth for coating objects with powder, in particular for powder painting, having a) a housing, in an upper region of which there is formed an air plenum, which can be charged with supply air via an inlet and is bounded downwardly by a filter ceiling, the housing having one or more walls; b) at least one application device in the housing, with which device powder can be applied to objects; c) at least one first extraction opening in a lower region of the housing, running along at least part of the one or more walls, via which opening a mixture of air and excess powder can be extracted and supplied to a recovery unit; d) at least one second extraction opening in a central region of the lower region of the housing, and adjacent the at least one first extraction opening, via which a mixture of air and excess powder can be extracted, filtered, and reused; e) the filter ceiling having a central region and a marginal region, wherein the central region consists of air-impermeable material such that the filter ceiling is air-permeable in the marginal region only, which marginal region is adjacent to walls of the housing; and f) an upwardly projecting apron separating the at least one first extraction opening and the at least one second extraction opening, wherein the apron partitions the total flow of air/powder mixture between the first extraction opening and the second extraction opening and wherein the position of the apron is adjustable so as to enable proportion of the total flow of air/powder mixture between the first extraction opening and the second extraction opening to be altered.
