Paint Arrestor Type Spray Booths
The ThaiPollutech dry filter spray booth has no washing chamber. Instead, the fan draws overspray into a paper filter at the back of the booth. This traps the paint and allows clean air to be exhausted. ThaiPollutech disposable paper filter consists of two sheets of heavy paper with corrugations of unequal sizes. The sheets are attached at the corrugations. Each sheet has rows of perforations staggered relative to the other – both vertically and horizontally. This give the paint laden air a tortuous passage through the filter and, in fact, it must strike at least four surfaces before leaving the filter. The result is that the sticky paint adheres and filtered air is discharged. The filter has a long life but when it is fully laden with paint it can be removed and replaced easily.
