Self Cleaning Downdraft Tables

AER Control Systems AER Powered Bench 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, the APB series 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. The AER Powered Downdraft Bench will help with compliance to local OSHA regulations by drawing contaminants away from the operator’s breathing zone.
