Dustless sandblasting equipment consists of a blast tank, blasting pressure gauge, an air inlet, an air inlet valve, and an inlet pressure gauge and adjustment. Dustless units also include a blasting pressure gauge, an abrasive control lever or knob, a vibrator, a blow-down or overflow valve, and a fill cap. Dustless sandblasters also use a blast hose and a nozzle head shutoff.Continue Reading
Low-volume, commercial and industrial dustless sandblasters feature some different parts. Low-volume blasters feature blast tank volume that is less than 2 cubic feet, a vibrator ball valve and a blow-down valve, but they do not have an overflow valve. Commercial-sized units feature both blow-down and overflow valves, as well as a pneumatic pinch valve and a control manifold. Commercial blast tank volumes range from 2 to 8 cubic feet, and industrial-sized dustless sandblasters feature blast tanks as large as 15 cubic feet, quick fill water inlets, a control box and bulk load fill funnels. Industrial units also feature forklift pockets.
Dustless sandblasters use compressed air to propel an abrasive and water mixture through a blast hose to remove rust, paint, dirt or other materials from a variety of surfaces, such as automobiles, walls, fences, furniture and boats. Compared to dry abrasive blasters, dustless units' intake and exit ports are positioned directly opposite to one another. A cone-shaped valve at the bottom releases compressed air, which mixes with a small amount of slurry made from abrasive and water. The slurry is then carried out the exit port into the blast nozzle.Learn more about Tools
