Wet machines eliminate frictional heat that can damage certain materials, in addition wet machines can operate with ultra fine abrasives i.e. 4000 mesh. Chemically clean part surfaces can be achieved using a wet machine. A slurry pump is used to suspend the abrasive and pump abrasive to the blast gun where compressed air accelerates the mixture.

Dry abrasive blast machines are the most common using frictional heat to produce a much faster part-cleaning rate. They require additional selections for abrasive delivery type, machine duty cycle, abrasive size usage and final cabinet sizing. Plastic and Soda are two very specialized applications,  Media Blast has created two distinct machine models for each abrasive type…use the short-cut link above and go directly to the machine literature.
