The Vapor Blaster operates by mixing water and abrasives inside the blast tank. The introduction of water significantly increases the mass and energy output of the machine while also eliminating dust. To illustrate, think of throwing a handful of dry sand versus throwing a handful of wet sand; the wet sand will have a more substantial impact on the target. Not only does wet sand hit the target harder, but it also avoids disintegrating into a cloud of dust like dry sand. This simple principle underlies Dustless Blasting.
