Topring 60.389 Airpro Maximum Safety Blow Gun 8mm 4 Inch Tube

TOPRING maximum safety blow guns exceed OSHA and other Health and Safety Agencies’ standards. If the tip of the blow gun is blocked, a safety check valve located inside the blow gun mechanism will immediately shut off the airflow. Thus the user will never be exposed to a dangerous airflow on his skin. When the nozzle is free of any obstruction, the valve re-engages to release air.
