A pneumatic effect that uses a HUGE 2″ high flow solenoid valve to expel a large amount of air with an accompanying loud noise as a startle effect. We do realize this air cannon is kind of ridiculous, but it proides a very nice “crack” sound when it fires. It’s the closest we have been able to come to a gun shot or cannon sound. Included is the air cannon assembly built on a 10 gallon air resivoir with solenoid valve and regulator. All you have to do is hook up an air supply and a power source. The air inlet on the valve is a 1/4″ push to connect fitting for tubing. If you need to hook this prop up using a standard compressor fitting, let us know, and we can swap it out for you, or you can just buy one of our adapters. The solenoid valve is 12vdc. This allows you to use a variety of sensor and controller options. If you need help picking a controller or sensor for your prop, please let us know and we can help.
