The combination of an air/water mixing chamber and atomising spray heads will dramatically reduce respirable dust that is produced.
Spray heads can be mounted at the rear of the deck for when tramming off the drill hole to crust over the cutting pile.
They can also be mounted under the drill deck for when drilling is in process. The design of the spray heads makes it nearly impossible for dust to clog them. The way they atomise the water creates a mist under the deck that is more effective at catching dust than spraying water out of conventional spray heads.
