Down Draft Bench

Rugged Bench with Downward Suction

The Sternvent Down Draft Bench provides a work surface with openings for a down draft to capture dust particles from power tool hand sanding or grinding of steel, fiberglass or composite objects.  Dust particles are contained within the bench and sucked down through the heavy-duty grating.

Sizes

Sternvent offers two models: DDB 1507 and VCB 36007 with work surfaces of   36“X 60 and 27”X56” respectively.

Principle of Operation

Dust particles are captured either directly by the downward suction through the grating or first hit the side shields and located on three sides of the table. A perimeter slot and baffle provides maximum suction at the front of the table. Suction is provided by the factory mounted fan. The fine dust particles are pulled to the filter pockets. A dust cake forms on the filter media, which assists in the filtration. Clean air is able to pass through the filter media and out the fan exhaust.  Excess dust on the filters is vigorously shaken off by the handle or motor driven shaker. Filtration efficiency is 99.9% for wood & steel dust.
