water-mist dust suppression system that is a significant improvement over hose jets.
The DF Smart Dustfighter is a compact misting fan which produces finely divided water droplets in the size range 40-120 micron diameter.
At this size the water droplets can easily combine with dust particles of similar dimensions and precipitate them out of the air.
Moreover - because the water mist produced “floats” - the mist covers and envelops the dust cloud more effectively than a spray from a hose.
A conventional approach to dust suppression - using a 15mm hose to spray down an area manually - will typically use 17 litres / minute (approx. 1000 litres per hour) of water.
