GD Energy Products‘s Air-Operated Control System for UHP waterjetting. This tool can take the place of expensive rotary air guns in most applications. The air-operated control gun works with your existing tumble box just like the current air rotary gun. Remove surface paint by combining the dual air trigger control gun with the StoneAge 40K Barracuda or straight sapphire nozzles or any other UHP rotary nozzle for surface preparation and coating removal. We also supply abras-injector cutting head for metal cutting, or a 3/8-24 UNF straight high-cohesive sapphire straight jet.
