The RS Wet Blast machines are designed to be used in a variety of applications. The principle of wet blasting is similar to dry blasting with the use of an abrasive media and compressed air. However, unlike the dry blast process, wet blasting uses a third element, liquid (water). Using water, enhances the level of finish, as well as having other advantages, degreasing capabilities, no dust production, and giving a smoother, more consistent finish. By lubricating the abrasive particles in a stream of water produces a uniformed flow across the surface, this giving the advantage of less risk of damage being caused to the work piece, and any abrasive action is consistent across the whole of the surface. The water and media mixture are stored within the cabinet’s sump, delivery to the blast nozzle is via a glandless polyurethane pump, which is submerged in the sump of the cabinet and externally driven by an electric motor. Compressed air is introduced to the media mix at the gun, this accelerates the mixture to provide an effective blast.
