Fully Pneumatic Air Locker Setup....

That's right, run the air locker (mine's ARB) with no compressor or extra wiring. Got the idea from a guy with a Samuri. Really small vehicle that he wanted to minimize weight and space taken. He was running both lockers off a 9oz paintball Co2 tank and an in-line 3-way pneumatic switch. The switch is normally off, flip it on and your locked, flip it off and it closes the valve and bleeds off line pressure. I regretfully didn't get any part #s from him but it seemed simple enough.

I've searched and searched and come up with nothing besides people claiming to have a setup, no pics or part #s or instructions.

I'm doing this on a budget as most do. ARB locker has been installed and working for a year now but I've recently ditched the compressor for a Power Tank. I want a separate small tank that I can fasten to my roll bar for the locker. Fully pneumatic is just so much more reliable, compact, light and quiet.

Here's what I "think" I need...

9oz Paintball tank $20


5-125psi Regulator kit w/20oz bottle $100 (much rather something cheaper and don't need the hose or big bottle) they don't sell the regulator alone



3-way pneumatic switch $60 (ordered)


I'm holding off on the regulator kit to see if perhaps you guys can help me out. I am pretty firm on using the more compact 9oz bottle. Just need a regulator to go from that to 1/4 NPT then the ARB blue line.

 

I'd hate to run out of CO2 at just the critical moment...

 

I think its a great idea. Greatly simplifies the hardware, and much less $.
I'd set the regulator between 80 and 90 psi for the ARB.

Don't know much about the little paintball tanks, though. Are they simply compressed CO2? Or liquid CO2, like the PowerTank?

You might not get too many locker activations from one tank.

 

Critical moment, no Co2.... winch

 

I'm looking at your ride on CarDomain. You've spent a ton of cash on this rig. If you told me that you were using the CO2 as a back-up to the air comp dying, I'd get that. Just seems like a weak link to me. Maybe you should get the comp, and get nitrous bottles instead.
