question about co2 on your 40

pbgbottle · 02-20-06, 07:18 PM

looking for some info on setting up a co2 on board air system , i got ahold of a co2 bottle ,i just need the reg . was wondering what any of you have used for a reg ,and where did you mount your bottle ,i can get a beverage regulator for free , but i have read that they will freeze up , any info or links to a reasonably priced regulator would be great . thanks

As to the location for mounting, anywhere that it is safe and secure. I used a co2 regulator that I got at a welding shop and have no problems freezing up. Great system. Good luck, Bill

HawkDriver · 02-20-06, 08:58 PM

Yeah, good question, and how small of a cylinder would be considered big enough?

Vitesse_6 · 02-20-06, 10:12 PM

I have a cheap regulator, It gets cold but hasnt froze yet, Then again I havent aired up more than 12 tires in one stint or run an air tool, 2 club snow runs and all is well, Im sure there are reasons for getting a good high flow reg. but I can live with what I have.
I still need to find a good mounting place, With the possablility of having kids in the back seat I need to find a better place than where it is now.
Good luck

I have a 20 pnd tank mounted to my rear rack, next to my jerry can and spare. I bought a regulator that I got from williamsballoon.com, cheap. Never had a problem with it. Unless you need the "super" fill valves that some vendors sell then just get a standard one with a quick release. I figured I could wait the additional 30 seconds to have my tire fill up. The tank also powers an air block in the engine compartment which I run my arb's off of from pneumatic switches. No electrical or solenoids to go bad, all mechanical and air driven.

On a side note, I have about 50 of these switches I need to get rid of. I bought them with a good friend when at one time we were going to be putting a company and kits together. Never materialized. That being said, if anyone wants a pair of switches, let me know.

I will be doing the ROTW later this week and will include more info on the switches setup, cost, etc.

will probably get one these , thanks for the reply's

1973Guppie · 02-20-06, 10:49 PM

can't quite remember, I think mine pushes around 100 psi, don't run air tools so no problems, static pressure is different than rated pressure so make sure you ask about this when you buy it, if you care that much about the exact output, pressure will drop I think around 20 psi from the rated pressure. Not sure if I go this right, just ask the place about it. Only really a prob if you are running tools and want a specific top pressure, filling tires you are golden.

mostly gonna be using it for filling tires another question ,how do i know which numbers are for the hydro date ?? theres numbers all over the place

Mark W · 02-20-06, 11:32 PM

If you are just using it to fill tires, you don't really need a regulator. Just use a lock on chuck and make sure it is on the tire stem before you crack the valve. Shut the valve off before you disconnect the chuck. It just takes a few seconds to air up a tire.

I carry a five pound bottle. I actually have two. They are small and easy to stow and carry around. By having two it is not a problem if a bottle goes empty on me as I am filling the tires. I just crack the second and refill the empty when I get back to town. The partial bottle goes in position one, and the now full one becoems the backup.

It has been a long time since I was filling 35 inch tires, but IIRC I was getting 3 sets of 35x12.50s from 10 to 25+ psi out of a single five pound bottle. Or one set of 42x15s and one set of 35x12.50s with the same pressure numbers.

I got my reg from a fire extinguisher supply place in town. They also refill my 10# bottle for me for $12, when they charge me at all.

wtmtnterror · 02-21-06, 10:04 AM

So you need a 20# tank for 35s or bigger?

pbgbottle · 02-21-06, 11:11 AM

i have a #20 bottle , i may want to use some air tools who knows so i thought i would try to get a reg , thanks for all the input people , but i also may have another problem the bottle i have may need to be hydro tested so my project is on hold , it is stamped luxfur 7 @ 98 20# CO2 TW23*8
DOT-3AL1800 what does a new hydro date stamp look like ??

whats a lock on chuck ???

I'm interested in a set of switches. I ran an ARB off of my Co2 tank in a previous rig and they work great.

Now I need some for my current project.

Let me know ...

Thanks!

pbgbottle · 02-21-06, 02:58 PM

another question about the coil hose
nylon or polyurethane
nylon max working pressure 200 psi (black nylon)
poly max 125 psi (blue poly)
both -40 F to +180 F
also which hose diameter 1/4 i.d. or 3/8 i.d.
my local parts place has both just not sure which to get

My buddy has a 20lb setup that he uses. He got the reg off ebay and it is adjustable for CO2 and hasnt frozen up yet, and he is generous at the end of the day in filling up others tires. He runs air tools too. It is a cool toy.

We were messing around with it one day and with the right (meaning safe) mounting brakets, like Nuclearlemon, it will fit right onto the rear roll bar (stock) and fit in the rounded area of the tub with or without the hard top. It looked sweet too sitting right in the corner window.

Where did you get your bottle?

Just another .02

i can AH! sorta get them through work pbgbottle PBG is short for pepsi bottling group .

snailwagon · 02-21-06, 11:06 PM

I use a beverage regulator on my 5# tank. I'm not too sure about how well it could seat a bead and it won't run air tools (output of only 40psi), but it will fill up my little 33" tires 3 times around with some left over. If you are working for a bev company, snatch an aluminum tank next time one slips through. Hose shouldn't matter much unless you really need much more than 125 psi.

Nope. As I mentioned above I can fill up to three sets of 35x12.5s from on 5 pound bottle.

If you don't air down extremely and don't insist on maxing out the pressure listed on the sidewall, you might be able to get two sets of 42x15s out of a 5 pound bottle.

For the past couple of years the areas where I have been doing my serious wheeling happen to have roadhouses located within 10 miles of the trailheads. So I usually just run down the shoulder of the highway to the rodhouse and fill up there instead. SO it has been a while since I had a completely fresh bottle that I ran empty airing up when we got back to the road. SO my memory may be fuzzy. I know that you can get at least as much as I mention above from a 5 pound bottle. You might get more.

A tire chuck with a trigger like lever sticking out at the head. You squeeze the lever to put the chuck on the valve stem and then release it. This locks the chuck on the stem until you squeeze the lever again to release it.

I've been running a Co2 bottle for quite a while. My original mount had it in the back passenger corner right next to the tailgate. A mishap, at Tellico, had me going backward down "school-bus" and another rig moving forward to keep me from going all the way down. Scary indeed. After the sudden stop. and damage evaluation. My tank mount (at the time a standard fire extinguisher mount) broke free and put the tank on a position where the regulator might have been broken off, by impacting my cage. The only thing preventing that was the handle that shrouds the regulator (powertank tubular handle deallie-O). That was the scariest thought of the whole ordeal. Had the regulator been sheared... Since then I relocated the mounting position to where in the event of a roll/crash, whatever, the tank and regulator should not impact anything at all. and in the off chance it does, it gets ejected from the rig, not into the driver/passenger compartment.

My mounting position will not work on a rig with jump seats as it is on the driver side wheelwell, horizontal, with the regulator right behind the driver seat. Yes I have to remove it to fill tires, etc..., but I don't mind. With jump seats it may be mountable beneath one on either side. All I know, is I feel much safer where I have it now.

A CO2 tank will not violently discharge like you are describing. You are thinking of compressed air or nitrogen tanks. Think of a Co2 fire extinguisher and you have a better idea of what would happen. Probably scary but not likely life threatening or "missile" like.

Degnol · 06-30-07, 01:17 PM

As to the hose, will either nylon or polyester work?

I did not know this, so that's why I placed mine where I did. Not to sound like a dick, but can you please provide back-up for this. I know the expansion rate of Co2 is much greater than air, and that is confusing me right now. It sounds like you know what you are talking about, but for those of us less knowledgeable, I feel it would make some of us feel a little safer with some back-up.
Since I got rid of the jump seats placing the tank where I did works well for me. The placement leaves very little risk of even chancing damage to the regulator. For me placement anywhere else just isn't worth the risk. I know it isn't ideal for everyone, as we all use our rigs differently, and are physically set-up to our own needs.

Again, I don't want to question you on the perceived "danger" just some explanation for education sake. I like to be well informed, that way if anyone asks why, etc.. , I can also pass along competent information.

pbgbottle · 07-01-07, 02:22 PM

i've heard this to ,that it won't violently discharge because of the phase change or something .from a liquid to a gas . but at work i deliver 50lb tanks sometimes and they told us it will rocket off like a missle ?

e rock · 07-01-07, 02:43 PM

Compressed air (in a tank) is still compressed air. If you break the valve off the top, all that air will want out fast - like 3000psi fast.

CO2 in a tank is not (all) in gaseous form. It varies with temperature, but at room temp, the tank will be right around 800psi. This is the 'balance' pressure. If the pressure drops (as you let gas out), more of the liquid CO2 will turn into gas to maintain equilibrium. This is part of the reason we love CO2 - about an ounce of CO2 in liquid form expands to about 5 gallons of gaseous. But it doesn't happen instantly, and it requires a bit of heat as well, so as the things around it start to freeze up, the transformation slows down as the 'balance' pressure drops (see graph below for reference).
