Need to learn CO2 Basics

I'd like to buy a kit because I'm lazy and don't want to piece something together. Basically looking to get a few wheeling trips out of a tank. 35x12.50-17's.

What do I need to know?

Thanks!

Powertank, also, 15 pounder.
It weighs 40-ish lbs when full. That's tank, reg, hose, boot and handle. A bit over 20lbs when empty.

Their website breaks down the capacity/capability of the various tank sizes.

I get my PT15 refilled at a welding shop, $14.

Initially bought it and used it for portable air power as opposed to using it for airing up...I don't air down much in my WJ. I was changing tires on my race bike...seating beads, running the air gun for axle bolts/nuts and topping off the desired tire psi. Considering the PT15 will run a 1/2" impact gun for 20 minutes straight(who needs it for more than a few seconds?), it lasted quite a while. Every race weekend was at least one complete tire changing evolution. Prolly woulda made it through near a dozen events for the season w/o refill but I didn't start with a full tank.

Floor mount bracket bolted just inside the sidedoor of my cargo/race trailer kept it convenient, secure and out of the way...transfers easily to garage duty at home.
Love it.

Oh, yeah...it airs up big tires, too. A lot of 'em.

Have a PowerTank PT10 in my unlimited and am very happy with it. (See my build thread for pics). Mounting can be a challenge if you have a soft top, because of the bows. Just about have to mount it where it's going to be in the way.

I bought Poison Spyder's c-pillar kit and mounted it to the upright, but it "just" fits. On a 2 door though, you might be able to mount it to the upright on the back of the cage. A PT15 will be big enough you'll be even more limited on mounting options.

I run at 28 PSI on the road and usually air down to about 12 -- that's on 37s. Never have run out on the trail, but I always run by my favorite welding supply for a top-off before I go. Fill from empty is between $15 and $20. Customer service is GREAT at PowerTank too. Great guys to deal with.

If you go that route, spring for the deluxe fill chuck with the gauge, will make tire refills a lot smoother.

I'm just going to pretend not to have read your post and say that you should build your own. I bought a new 10# aluminum tank from a beverage supply site for $80, a fixed regulator ($40) and bracket ($???) from Synergy, and a coiled air line ($10 maybe), and fill it for $12. All in, about $160 bucks for a great 10# setup. Powertank is WAY proud of their shit, if I remember right the same setup from them is $350-400 or something. Doesn't make a lick of sense to go that route unless you like pissing money away, and if you like to do that just send me the $400 and I'll send you a 'Powertank'.

If you decide to build your own, PM me and I'll hook you up with the sources.

Two points in that info aren't correct nor completely helpful. Not knockin' the info so much as allowing that it's not gospel. (I didn't read it all).

1) If you want to run an air gun, do you want it being pushed with 150psi from a static regulator? With the depth at which the other aspects were covered, coverage of adjustable regulators woulda been a plus.

2) The tank pressure is not a constant 800psi until it's empty. It varies with temperature and the percentage of fill. Typically, you will see near 900psi on a fresh charge.
Generally, your refills are 70-75% max which is a good thing on the side of safe. A 100% fill will begin to skyrocket in pressure above 88. Either way, not to worry if you have a proper set-up; A) they have a safety blow-off valve, B) the bottles are rated beyond 2000psi.
As the fill gets used, you will see a slow decrease in tank pressure down to 700-ish psi. When you get there, start looking for a refill. It will more quickly decrease with the same usage down to 650-ish. At that point, you won't be airing up but you could set a tire or two that may be running a few psi low.
Then it's dead.

10-4....

First go <<< HERE >>>

Then go <<< HERE >>>

Then find yourself a coiled high pressure air line, I found mine locally at Harbor Freight or something.

And optionally a mounting bracket. Poly Performance used to sell a nice bracket and line that were non-Powertank (in other words less expensive) but it looks like they stopped.

Get it filled, done. Unless, as mentioned, you want to run air tools. Then you'll need to cough up 80-ish bucks for an adjustable regulator. If you're feeling all self-conscious about your bare aluminum tank, you can paint it and even throw one of them fancy Powertank handles on it and impress your mall crawling buddies.

i bought the power tank setup, but have since swapped to an exchange program at my local gas supplier. the power tank regulator is awesome because of its dual gauge and the ability to adjust pressure. who wants to fill a bike tire at 150psi?

local swap is 20 bucks after having a tank (90 bucks)

Built mine too...

...Then sold it for like $270 or so. Used a $40 Ploly reg, though this time I am usinng a 100psi Wilson unit since I have no air at my house.

Skip the HF air hose, you want something good for at least 300psi that wont explode due to the temp. You can find them online in different colors from $12.

Forget shiny bottles, most places exchange bottles unless you sign up for CO2 delivery like the restuarants do now.

I think I have $130 in my current setup, not counting mounting and paint.

I have a tank system that I used for a while but between messing with the room it took, strapping it down safely, the hassle getting it filled and worrying about it running out after a few uses, I went back to using a pump. I was one of the lucky ones that got the Smittybilt pump for $25.

The tank worked very well but before you invest the money, check around and make sure that you have a welding shop or someone convenient who will fill it for you. Some shops will only swap out tanks and others only fill on certain days and require you to leave the tank for several days. I've moved around quite a bit and some cities were easy to get a refill/top-off while you wait and some towns just sucked. (and were expensive)

Makes perfect sense.

So find a welding shop that fills bottles or does exchange. I used to get O2 and Acetylene bottles swapped out all the time when I was a heavy equipment mechanic. Would if be better just to get a 10lb welding O2 tank? I want to get a regulator that I can adjust.

Poly still sells the mounting bracket.

Put the regulator on the Poly valve. 150psi in ----> adjustable psi

I have 5 and 10# bottles but can't find the things to protect the valve.

Ideally it would be a clamp on deal as I exchange bottles.

Any ideas?
Thanks in advance.

I just went and looked and I'm not as cheap or dumb as I first appeared to be. It's a Viair branded line. Still cheap in price at 12-ish bucks.

As far as filling goes, luckily I have a shop nearby that fills your own bottle while you wait. Nothing wrong with exchange programs, but I like to keep and maintain my own bottle since I know how it's been handled and treated. Some places don't offer that as an option though.

A FE place can fill it with O2?

Yup. The welding place told me as well so I asked aorund my club and below is who they all use as well. Many of the welding supply places around here were bought up by one company and they no longer fill at satellite locations. They have 2 places and don't do walk ins and they only exchange with a few day wait.

This is who I use locally:

Do you get it filled with CO2 or O2? What's the difference (besides Carbon)? I was serious when I said I need to know the basics. Thanks!
