SCUBA tanks for filling RV tires?

[Popsie]

I have a vague memory of some folks getting a SCUBA air tank pumped up to very high pressures, then carrying the tank (with a pressure regulator) to quickly and accurately fill RV tires.

Do any of you have experience and/or opinions about this settup?

Please Google the phrase "Not Interested", if you're unsure as to the meaning of it. Geeze.

"JC" is correct - on the info.

Many forums with lots of Co2 info - *if* you simply enter "C02 Tank Systems" on Google.

Yep - being informed *does* take a lot of effort, ROTFL !!

We carry a porter pancake compressor.

Actually "some" of us don't.

OP - SCUBA tanks are not practical for numerous reasons - like expense.
Refilling (to high pressure) is a PITA, and can be expensive also - and, of course it's still air.

Look into C02. Off roaders have been using it for years. Inexpensive tanks, and easy (cheap) to fill at home brew, paint gun, and welding shops - to name a few.

Check out the businesses selling same, such as - Powertank - and the applications (like RVs) - then check on DIY for way less.

Air (in a tank) can't compete with the expansion ratio of 450:1 !!

BTW: "Powertank" has a nice FAQ list - clicky here

Wow, for those prices I think I'll stick with a good ol' air compressor. Use the rest of that $500+ to buy fuel.

Obviously - You missed...."then check on DIY for way less"..:R

NO $500 necessary!...:W

Any of the many off road forums will have the details and photos of the components.

Google (Jeep forum) - "Build Your Own C02 Tank System - Highest Quality & Lowest Cost".

I found some prices on the components were less than on that 2011 post. (My cost was less than the $162. indicated, all new components w/ aluminum tank)

And - with the 450:1 expansion ratio, I've topped off tires for several years now - still on the same tank fill. (which was $10. at a local home brew shop - even bought a couple of beers -to go- while I was there, LOL).

Other benefits: pressure "right now", NO 12V or AC power required, NO noise - and it's lighter than either one of the two "portable" AC compressors (capable of 100 psi plus) that I used to take along.

But hey....whatever works for you!..;)

If you have generator power available I think it’s a lot less hassle to just carry a compressor.
You have all the air you need, no having to take your tank to a welding or dive shop to get it refilled.
If you don’t have power available, then the scuba tank starts to look interesting.

I think any local welding supply place will fill them with non breatheable O2.

O2 is very flammable if a tire should catch fire or explode. Is that a good idea?

Only with an oxidizer. O2 by itself is inert. You could always pick up a bottle of Nitrogen and be cool with that, green valve caps and all...

I believe from my safety training that O2 is the oxidizer so any flame will be made worse in the presence of O2.

It seems to me that a likely tire mode of failure would be the bead blowing off the rim before the tire material itself failed. No evidence one way or the other tho.

it can happen either way... rims also break or bend allowing an extremely dangerous situation.
when unchecked pressure is being added, its inevitable that something will give way, but a tire in good condition is pretty tough...

I still have my first US Divers tank from 1963 and it still passed the visual and hydro inspection at last fill up. Having said that when you think of a visualinspection every year, a hydro every 5 years, the availability of dive shops where you travel, the worry of damaging the regulator during a crash or bad road. It is a lot easier to stop at Flying J and just air up when you get gas.

It is a Cambell-Hausfeld horizontal. It barely clears the storage opening vertically but it has done what I have needed from it. I had to spend a bit of money on the air driven tools. The more inexpensive ones I have had for years would hardly work. The ones that will work at a lower CFM ask a fair amount more of money.

I wish that the cordless technology at the time was were it seems to be today. With the cordless impact guns that state they can be used on lug nuts.

I can get mine loose with my current setup but it will not drive the nut to full torque. It gets close but I use a 3ft breaker bar for the last little bit, then check with my torque wrench.

I like the helium option. The lift will save rolling weight...

At last, a method for getting within your truck's weight rating.:)
