Brochure features the batch powder booth with non-rollaway collector modue. The product's purge control is designed to ensures the safe operation of the coatings enclosure, by maintaining the airflow at design levels. During operation overspray powder accumulates on the cartridge filters. As the cartridge filters load, airflow decreases and negative pressure rises within the air handler. A timer activates a system of air purging valves that clear the cartridge filters of accumulated powder to ensure maximum filter life.
