If you have not already heard about these guys check them out amazing programmable controllers!

This is the controller and sensor I used for my Air blast prop.

other parts from Lowe's, and evilulisions.com, Tractor Supply.

I started with a 5 gallon Portable air tank from Tractor supply. Normal retail price was 14.99 but happened to catch a sale which was 4.99 ea. Bought 10 that day. Got vary lucky lol So look and watch for sales. Even might find at yard sales.

I took the Supplied fittings out of that tank and went to lowes with fitting in-hand to find the Size of the inlet hole on the tank.

Mine turned out to be 1/2" thread.

NOW WARNING these tanks are only designed for 100 - 120 psi! Anything more could result in tank failure so caution needs to be addressed to not exceed that mark!

Now I purchased the following parts from lowes!

2 - 1/2" Black Iron tees
1 - 1/2" 45 Degree elbow
1 - 1/2" Ball Valve
1 - 1/2" 90 Degree Elbow
1 - 1/2" to 1-1/2" Reducer
1 - 1-1/2" x 2ft Pipe
4 - 1/2" x 1-1/2" nipple
4 - 1/2" x 3" nipples
2 - 1/4" x 1/2" Reducing Plugs
1 - 1-1/2" Flange
1 - Quick Connect Male Air Hose Fitting (Tool Department)
1 - Quick Connect Female Air Hose Fitting (Both have Male Threads!)
1 - Roll of Teflon Tape

From evilusions I ordered the following

1 - 1/2" 2 way valve
1 - 1/2" Pressure Regulator

Starting at the tank and working out I inserted a nipple then the 45 degree elbow. The inlet on the tank wasn't on the top. Then another nipple the a tee in the way that top of the tee was in the vertical direction. Off the leg of the tee was another nipple the the pressure regulator another nipple the check valve. Be aware of the direction on air flow. Another nipple and then the ball valve. Yet again a nipple and now the leg of the second tee. Now on the top of this tee I installed the 2 1/2" to 1/4" Plugs. Then I installed the 2 Quick connected Hose fittings. The Female fitting has a Locking system so that if nothing is connected to it. It seals the line from bleeding off air pressure.

This set-up allows several tanks or props be strung together via one compressor. I set the line psi level at the compressor to around 70 psi and the pressure regulator to about 30 psi. This means the Main line always has more air pressure than the tank! The check valve also mean that once the system is pressurized the Prop always has the air it needs to work.

Back to the air blast. Now off the tee above the tank is a nipple and the 2-way valve from evilusions. This is a 12v solenoid valve which i controlled by the efx-tek controller wiring documentation is on there user manual.

On the out side of the valve in a long nipple and the 90 degree bend the another long nipple and the 1/2" to 1-1/2" reducer and the 1-1/2" pipe and flange. I then bolted this whole unit to my wall panel to keep it from falling over.

As you attach these parts keep in mind how the weight effects the tanks supports and if you rotate them you can balance the tank nicely.

This can be made to fit inside a create or hidden in the bushes it's a great effect and will catch people off guard. You can feel the rush of air several feet away from the end of the nozzle. Another warning here I would not point this blast directly into the face of your patrons being there might be metal shavings left over from the cutting of the treads in the tank.

I found that above about 60 psi the 2-way valve didn't want to open anymore so that is your max psi. The best location for the blast is around lower waist to mid leg area. this will give you a loud blast of air and defiantly move cloths!

I will try to get a post on youtube of the test fires so you can see the way i have it piped and hear the sound it makes!
