- The Airflow Systems PowerBooth is a self-contained, highly efficient dust collection system that eliminates the need for costly ductwork required with a central dust collection system. The PowerBooth features a powerful, high-efficiency, 5HP direct-drive blower, and a compact, high-density cartridge filter that provides up to 99.97 filtration efficiency. The Vibra-Pulse® cleaning system with offline cleaning returns filters to an 80 dust holding capacity; 4-times cleaner than reverse-pulse cleaning.
