Pneumatic device that fires compressed air to create wind, debris, or explosion effects – controlled burst for safe, repeatable on-camera action.
What is an Air Cannon?
An Air Cannon (Luftkanone) is a pneumatic device that releases compressed air in a controlled burst. It creates wind effects, propels lightweight objects, or simulates the shockwave of explosions – safely, repeatably, and camera-friendly.
