The types of overspray collectors associated with spray booths can be categorized into venturi scrubbers, waterfall scrubbers, dry filter, and cartridge filter. Venturi scrubbers use a high-velocity water spray to capture the overspray particles in a turbulent zone. Waterfall scrubbers use a curtain of water flowing over a perforated plate to wash down the overspray. Dry filter collectors use a series of filters, such as paper, fiberglass, or synthetic media, to trap the overspray. Cartridge filter collectors use pleated cartridges with high surface area and efficiency to capture the overspray. These collectors also have a self-cleaning mechanism that uses compressed air to dislodge the overspray from the cartridges.
