I have CO2 but no on board air and i don't want to buy an ARB compressor so what gives can i do it?? I know how, i just don't want to buy the fittings and stuff fo find out that it won't work. My ARB is used and i did not get it with a pump.

From what I understand, it works--sort of. It takes 80 psi to keep the thing engaged. that seems high, but there isn't much volume, so it'seasy to acheive. The problem is that there are always leaks in the system, which is why you hear guys compressors cycling on and off.

If you hooked it up to a powertank or whatever and had some kind of switch/regulator/valve that would open when the press. is below 80 psi, you'd be in business.

I'm not sure how long the tank would last though. From what I hear those things are pretty amazing, but if you're on a long trip and you're out fo air, you're SOL.

I run mine on CO2, just make sure it is regulated at 80 psi. It is actually better for the solenoid than air, no contaminates and no condensation.

CO2 works great for ARBs.. I've heard 90 PSI so you might wanna call ARB and confirm. My compressor cycles between 85 and 110 psi approximately.

great pneumatic switch for your ARBs. works with CO2 and air.

good luck!

Something else to think about

One guy in our club uses paintball co2 cannisters to run his ARB's. One little bottle will run them all weeekend and you can easily carry spares.

All I gotta do is drop my hand down and flip the switch ...

If you look close you can see the toggle for the ARB at the bottom left front corner of the Tuffy. There's room for another if I want to add an air locker to my rear ...

Thanks a bunch guys, i am going to but one of those switches right now and get it hooked up to my co2. Hopefully it will be fully running in time for the clean-up.
Thanks Again. <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0">

side note... the cold co2 makes the lines britle

i just got an e-mail back from ARB

You shouldn't have any trouble running a C02 bottle for the Air Lockers.
The pressure needs to be between 80-100 PSI. If you need any help with
wiring your switches or solenoids please call and I can talk you through it,
or if you have any other questions.

Or contact Steve at Powertank, he has been doing this for years.

The ARB pressure switch turns on @80 and off @100 so just regulate it at 90 and go. CO2 would be the way to go if you don't minde buying CO2 but the bottle would last for a long damm time at the rate they would use it up.

The CO2 setup works great but if you use the tank to also air up tires, a 100 psi pop off valve (Power Tank sells them) is a MUST.
All it takes is one boo boo to blow out the ARB if you forget to take the pressure down from 140/150 psi after airing up.

Can we use a 90lb regulator from a "T" line after the 150lb regulator?? Or instead, what would be the downside to running a 90lb regulator all the time? Would it slow down airing-up tires too much? Don't plan to use air tools that much (who am I kidding!).

There is no reason I can see why you could not use a 90 lb. regulator banching off a regulated 150 lb.line if you wanted to go that way.
The big Power Tank hype sez that their regulators won't freeze up. Mine doesn't.
Apparently most smaller capacity regulators will freeze with continuous use.
On the other hand, try finding a 90 lb. regulator ...

Yeah you could put in a tee and add another regulator dialed in to 90 or so lbs. No need to worry about freezing since there is very little flow. Once the system comes up to 90 psi (just a second or two) the flow stops and whatever is in the line at that pressure adapts to the ambient temperature. It doesn't stay cold if there is no CO2 flowing through the line.
