Powered Downdraft Bench - APB Series

The AER Control Systems AER Powered Bench Downdraft Tables are designed to provide efficient and cost  effective control of; dust, smoke, fume, and gas/vapor contaminants generated from a variety of  manufacturing process applications. The APB series tables are typically used for control of moderate to heavy  concentrations of dry contaminants, and can also be used for grinding, polishing, and dry buffing. The self-cleaning system can be either manually or automatically controlled to minimize maintenance and reduce  replacement filter costs. The AER Powered Bench will help with compliance to local OSHA regulations by  drawing contaminants away from the operator’s breathing zone.

The AER Powered Bench unit comes standard with flame retardant filter cartridges, a TEFC motor with  non-overloading direct drive blower, dust drawers, and sealed doors with tool-less access to the filters. Two  table top sizes are available: 42’’x50’’, and  42’’x76’’. Table top air velocities are approximately 200 feet per  minute. Typical table top loads for the bench are 75 lbs per square foot.

A variety of filter options are available, the type of filter used depends on the contaminant. If smoke is  present an additional HEPA cabinet can be added. For inquiries about replacement filters visit  AERFilterSales.com.
