Dustless blasting utilizes water to reduce airborne particles; when the water and abrasive leave the nozzle of the blaster the water encapsulates the abrasive, and when it hits the surface, it crushes and breaks up the layer on top of the surface and the water traps it. When the water leaves the surface it takes both the abrasive and broken down particles of the layer being removed with it. One benefit of dustless blasting is that it reduces the containment required for the task and the cleanup much more efficient.
With no toxic dust being released into the air when using this method of blasting, a blast suit is not required, this increases your visibility making it a more precise method. Similarly, the water used in dustless blasting reduces the surface heat of metal when the abrasive causes friction. By reducing the temperature of the metal, the risk of the metal being warped is significantly reduced. Dustless blasting can be used on a variety of surfaces including wood, metal, masonry, concrete, bricks and metals.
Not only is dustless blasting beneficial for the environment and when using metals, but it is also beneficial for the equipment; less abrasion due to the use of water, means less wear and tear on the parts of the equipment like hoses, nozzles and valves.
