The heart of Dry Back Spray Booth is the special disposable paper filter. This filter consists of two sheets of heavy paper with corrugations of unequal size which are attached at the corrugations. Each sheet has rows of perforations staggered related to the other, both vertically and horizontally, resulting in a tortuous passage, so that the air stream strike at least four surfaces before it leaves the filter. In doing so, the sticky deposits strike the surfaces and adhere, only the air being finally discharged.
