A dustless sandblaster, in short, is a combination of an ordinary sandblaster, a vacuum cleaner and a special filter system.
The sandblasting nozzle is closed in a brush head that acts as a suction cup. The head is connected to the suction hose. During sandblasting, the abrasive thrown out by the nozzle, along with dust and stone remains is sucked from the sandblasted surface into a machine closed circulation system. Our abrasive is recovered in this system. In addition, it is separated from dust and fine stone residues. This is done in three steps.
The heaviest abrasive falling into the loading hopper falls to its bottom. This is due to the optimal configuration of the suction motors, tanks and nozzles, thanks to which the abrasive is not sucked into the subsequent filtering stages. Dust is further sucked into the cyclone filter, in which its heavier particles are retained. The lightest dust is trapped in the third stage by the air filter and falls into the trash can drawer. Over and over again. Depending on the quality and type of the abrasive, it is possible to perform a significant amount of work using the same abrasive.
Thanks to this solution, we work cleanly and safely. We only see dust when it is ejected from the machine. For sandblasting, we only need goggles and gloves.
You will agree with me that it is already paying off.
