Self Cleaning Downdraft Tables

Our self-cleaning downdraft tables are designed to provide efficient, cost-effective control of dust, smoke, fume, and gas/vapor contaminants generated from a variety of manufacturing and process applications. Typically used for control of moderate to heavy concentrations of dry contaminants, this series of tables can be used for grinding, polishing, and dry buffing. The self-cleaning systems can be either manual or automatically controlled to minimize maintenance and reduce replacement filter costs. Our self-cleaning downdraft bench will help with compliance with local OSHA regulations by drawing contaminants away from the operator’s breathing zone.
