Wet dust exhaust units are often specified to cope with the heavy burden of flammable dust arising from Grinding, fettling, linishing, polishing and trimming applications.
Wet dust exhaust units draw the dust-laden air through a tank of water. Heavy dust particles are thrown directly into water and settle as sludge in the base of the unit for subsequent removal. Air and light dust are drawn over the surface of the water and scrubbing cups turn the air and entrained water, wetting even the very fine dust particles. A series of baffles removes the wetted dust and clean air is discharged from the top of the unit back into the works atmosphere
