Paul,

Just curious, where did you get your 20# tank? Welding supply store maybe?

Mick,
You got it. I originally had a 15lb cylinder, and I work at a bodyshop so I just called my welding gas supplier they didn't have a 15lb cylinder to swap out so they sent me a 20lb one.

I could not get a power tank here in the UK so I put together my own system using a diving air cylinder:

Would certainly not recommend mounting this externally due to the high pressure and putting together your own system based on a Co2 cylinder would be a better idea (lower pressure), but cheap and relatively easy if you have the skills or know the right people.

CO2 works great. I have the ARB compressor to air up but also have a home built CO2 tank with a 100psi fixed regulator on it. I use it to air up in bad weather, run air tools, reset beads, sheld gas on welder, and most important also could be use to cool a warm beer.

the same size CO2 tank has more tire refills than a dive tank, because the CO2 is stored as a liquid.

Robinhood 150, thanks for the humor reply, I'm new around here and don't want to start off badly. I like to srew-up over a long time

codlord

You may be wrong there - it is true that CO2 is stored as a liquid and the liquid gives off gas as you use it but you have to remember the air in the dive tank is compressed to say 200 bar so in my 12ltr air tank I have maybe 2400 litres of air.

When I was looking at the Power Tank I worked out that the equivalent sized CO2 cylinder had about the same capacity as a 200 bar air cylinder.

Of course my calculations could well be completely wrong

A C02 tank such as my Power Tank at 10 lb will fill way more tires than a scuba tank.

Call or write Steve who owns Power Tank, and he will give you the scoop, with no bull.

One 10 lb tank such as mine can air up 34 tires or more.

I may try assembling a home-grown CO2 tank, found a 10 lb aluminum one for under 100 bucks, just need regulator, tubing and such.

Mad Chemist

Hey guys,

Just bought a 10 lb. CO2 tank off ebay for 55 bucks. There's a company in Cali thats selling a bunch of gas related items, 20 lb aluminum tanks on there as well, and cheaper than anyplace I've seen on the web.

SteveS and Seafarinman are right on with the best of both worlds - air comp. and Co2 together on the same rig. I could never justify the added bulk/weight of an air tank (for compressed air) for what I perceive as a small benefit - a short supply of "powered" air above what you are already getting from your air compressor (provided your air compressor has a good output). Unless you have a huge tank, I don't see it really doing much. And a huge tank is not practical. I guess if you had a really slow compressor, it would be advantageous to store some air in a tank, but why not just put the cost of the tank into a more powerful air compressor and save some space? Thoughts? Opinions?

Mad Chemist

Well, I guess I'd disagree about CO2 as being a short supply. A 10 lb cylinder is enough air to fill about 35 tires, or run an impact wrench for 20 minutes. No reliance on electricity, and significantly faster airing-up time. I'm guessing that I will probably be able to air up about 4 rigs in the time that it takes a compressor to finish one. No maintenance, no parts that will burn out eventually. I agree, having both would be the best of both worlds. The speed factor is the biggest for me. Especially now that I've been offroading at night, spending an extra hour getting everybody aired back up means I get home close to or after midnight. I'm thinking I can people to chip in a buck for people that want air, will offset the ~10 bucks it will cost to recharge the cylinder.

BajaTaco

You misunderstood me. I was referring to an AIR tank, not a CO2 tank. The guy who started the thread was asking about running an air storage tank under his 'runner.

I had a 2.5 gallon air tank with my ARB compressor and that helped out a lot. It took about 2.5 minutes to get up to pressure from empty. It allowed me to engage and disengage the ail locker 40+ times before the compressor went back on.

With my current set-up (Viar 450) I will try and fit a 1-gallon tank under the ARB bumper. Maybe two of them if I can find the room. I wanna make sure I put them where they will not be exposed to rocks.

I like having the tank but am not sure how much it really helps for airing up tires. It shaves off some time that's for sure.

Mad Chemist

My bad, I agree with what you said.

RidgeRunner

I just talked with my local Air Liquide America Corp and they exchange 10# aluminum tanks for $11. You can buy the first one from them for $99 and they have inline 150# regulators for $30.
He said he may have mounting brackets that would fit too.

I figure I'll get a hose and tire fill fitting from the auto parts store of my choice and I'll be all set.

Found them in yelo pages under Welding Equipment & Supplies.

Sounds like it might work over the phone, I'll let you know after I look at everything.

Hey Mick,

You might want to check out these guys:

Only 56 dollars, with about 2 hours left on bidding.


I think there are alot of places to fill these tanks.

Thanks for the tip, David. I'll see what I can do.
