The Dustless Blaster works by mixing water and abrasive inside the blast tank. By introducing water we're drastically increasing mass and energy the machine is putting out, while eliminating dust. Imagine throwing a handful of dry sand, versus throwing a handful of wet sand; which one is going to have a more significant impact on the target? Not only will the wet sand hit the target harder, but it won't disintegrate and become a cloud of dust like the dry sand will. This is the very simple principle behind Dustless Blasting.
