Abstract
Abstract A paint spray booth with a filter and means within the spray booth to incinerate paint from the filter. A filter particularly adapted for collecting paint overspray in a paint spray booth. The filter has a plurality of members with a first portion parallel to the path of the air and paint particle flow which is to be filtered, each of the members having a second portion extending normally in a first direction from the downstream side of the first portion. The second portions of the members are spaced from each other and form openings therebetween on a plane normal to the flow of air and paint particles. Each of the members has a third portion extending from the other side of first portion and in the opposite direction from the second portion, and the third portions of the members form slots between members with areas less than the area of the downstream openings. Each of the members also having a fourth member extending perpendicularly from the end of the second member opposite the first member toward the third member, and a fifth member extending perpendicularly from the end of the third member opposite the first member and away from the first member.
