Air guns deliver a high-pressure airstream to clear chips and debris, cool or dry machinery and parts, eject or convey parts, clean hose assemblies, and more. Also known as blow guns, these pneumatic guns allow cleaning at a distance and while machinery is running. Their handpiece connects to a compressed air supply and has a trigger or other actuator to start and stop airflow. They accept nozzles that amplify, direct, and modify airflow. Accessories restore the function of air guns or modify them for specific applications.
