Blasting guns and nozzles connect work with an abrasive blaster or compressed air source to clean surfaces, remove paint and rust, and debur parts. Blasting guns direct blast media to the work area on the part being processed. Blasting gun nozzles push the combined blast media and compressed air over the workpiece. Air jets work with nozzles to control the amount of air that flows through the blasting gun. Mounting brackets install inside a blasting cabinet to support a blasting gun so workpieces can be held with both hands.
