BESCHICHTUNGSKABINE FUER DAS ELEKTROSTATISCHE AUFTRAGEN VON PULVERFOERMIGEN STOFFEN

摘要

A coating booth for the electrostatic application of powdery materials onto workpieces. The coating booth has a generally tubular configuration which when viewed in side elevation is generally oval but with a spiral curved bottom front wall which melds into a flat bottom surface extending toward an outlet at the bottom of the rear wall of the booth. On the rear of the booth there is a fixed fan module to which a removable filter module may be attached so as to interconnect the booth air outlet with the suction fan module. This construction facilitates quick color changes of the powdery material by maintaining a minimum deposit of powder on the interior of the booth and by enabling the filters to be interchanged without the necessity of first cleaning the filters or of interchanging individual filter media before restarting the booth with a new color.
