The WDT-3500 Walk-Around Downdraft Bench cartridge dust collector offered by ProVent, LLC is the ideal ventilated and filtered work station for hand tool applications that need room to maneuver. An integral fan produces 3500 CFM (6000 cubic meters/hr) which converts to exceptional capture velocity at the work deck. Large locking casters keep the unit in place where it is needed. No connecting duct work required. (4) cartridge filters do the filtering for the process and reverse pulse filter cleaning keeps them refreshed for repeated and uninterrupted use. Packaged as shown, the machine is ready for use upon arrival. Great for operator morale and keeping dust off the finished product and out of the plant environment.
