Hydrotron DHYD Wet Downdraft Table Series

The Hydrotron DHYD Wet Downdraft Table is a self-contained workstation with an integral water dust collector, drawing the dust directly into the water filter system. Immediately wetting the dust and thereby reducing the risk of fire, our wet collector downdraft tables also meet OSHA and NFPA standards for dust collectors located inside the building. The DHYD is available with one or two (back-to-back) work surfaces; each work surface may be equipped with transparent sides for containment and a regain air plenum at the top. The DHYD’s optional regain air system enhances capture velocity by returning a portion of the clean, filtered air through a plenum across the top of the station to “push” the dust away from the worker’s breathing zone while it is simultaneously “pulled” into open table-top inlet.
