Wet Downdraft Tables
For Magnesium Dust Capture
The HydroAIR™ 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 the HydroAIR 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.

HydroAIR after filters are
easy access and easy to clean. |
