Self-Cleaning Downdraft Tables

The self-cleaning APB Series of downdraft tables have been 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 manually or automatically controlled to minimize maintenance and reduce replacement filter costs. The APB units assist with compliance to OSHA regulations by drawing contaminants away from the operator's breathing zone.

All APB self-cleaning downdraft table models include the following features:APB4250 with flame retardant cartridges exposed

  • flame retardant filter cartridges 
  • TEFC motor with non-overloading direct drive blower
  • dust drawers
  • tool-less filter access door with easy filter change out
  • integral compressed air tank that can be easily operated via a simple pushbutton for pulsed removal of all collected particulate; particulate drops into an easy to remove tray for disposal
The APB-4250 is a self-cleaning downdraft table
