A pneumatic and fog effect that uses a 4″ venturi to expel a large amount of air and fog as a startle effect. It’s intended to simulate a steam pipe blast. Included is the air cannon assembly built on a 10 gallon air reservoir with solenoid valve and regulator, fog machine, fog reservoir box, and controller. 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. This is considered a finished product, so we provide and program the controller and sensor. We will generally provide a retro reflective sensor unless asked to do differently. If you want something specific please let us know and we can help.
