The NFPA package enables customers to fully comply with  NFPA 484 guidelines for combustible metals such as aluminum, titanium, magnesium and others.  By strictly adhering to NFPA guidelines, our wet dust collectors provide for shutting down the collector AND the dust producing equipment via control panel interlock on water level and airflow warnings.

*NFPA The power supply to the dust-producing equipment shall be interlocked with the airflow from the exhaust blower and the liquid-level controller for the collector so that improper functioning of the dust-collection system will shut down the equipment it serves.

The Sani-Ball cleaning system utilizes powerful spray nozzles to simplify the cleaning process
