Wet Downdraft Tables For Magnesium Dust Capture

Our wet downdraft tables for magnesium dust capture are very similar to the units designed for the collection of aluminum and titanium dust. Since a byproduct of the combination of magnesium and water is hydrogen gas, safety regulations (NFPA 651) require continuous and uninterrupted exhaust of the combustible gas.  To meet this requirement a magnesium constant ventilation fan has been design and incorporated in to our units to allow for exhausting of the tub 24/7 once magnesium dust is present. Electrical controls for the control of this design are incorporated as part of the equipment.
