The Barrel Blaster is ideally suited for processing a wide variety of small parts that are too small for conventional endless rubber belt and metal flighted Tumblast style machines. Reducing pinch point problems, the Barrel Blaster allows smaller parts to tumble uniformly in the abrasive blast for optimum cleaning and surface preparation. The compact design saves valuable floor space and permits easy installation. The Barrel Blaster machine is delivered ready to set in place, and pre-wired for immediate easy connection to the user's power supply and ventilation system.
