CO2 & Tire inflation

[almac]

after looking at several on board air compressors, i stumbled across the 'powertank' system.

a bit on the expensive side tho...


I then i saw this at cambodian tire:

i wonder if a 9 oz tank could fill a tire or two?

anyone use a CO2 system for their off roading needs?

If you used this, how would you go all James Bond and breathe from the tire while your whole vehicle is underwater?

i'd use my pocket underwater breather instead!

Hey,
I wonder if you could use a decommissioned Scuba tank to accomplish the same thing.

Gary-O has a big ol air tank underneath his.
Looked like just a typical compressor air tank.


Right On!

[Mr. Flibble]

I think a used SCUBA tank would work perfectly, and be a whole lot cheaper! Would you want a regulator on it so you don't detonate your tires with the pressure though?

*EDIT* I can see in the links people do exactly that.

Ghetto version seen on the Zuk Samurai crowd (here and there believe it or not);

• Talk to construction buddies, who has a dead air compressor.
  
  Take off there hands, suggest they buy you a six pack of bud for doing so.
  
  Take off the motor and air pump, maybe put leftovers beside the cans in recycling, for someone else, cause there's only one earth ya know.
  
  Go bug the guy at the C tire auto desk (it always seems like you are) get some fittings; hose, filling end, valve for filling, etc.
  
  Two ratchet straps to hold it down behind the seat, lets be safe here.
  
  Stop at a gas station, and by overworking their air pump, fill the tank.
  
  Buy coke's all round, this may be thirsty work (save bud's for later).
  
  Let plenty air out of all four tires while your still at the station (everybody else can wait), fill em' back up with your air tank.
  
  If there was enough air, fill'er up again and enjoy your air tank; that with time takes on a beautiful brown crusty patina in the back of your Zuk.

Of course anyone in the Delica crowd would do this far better; ie, tremcald, a handle or a nice permanent home for the tank.

I have a couple scuba tanks. Regulators aren't a big deal to find
since in my paintball days that's what you needed .. anyway
won't get into that.

But one thing is you can't have them filled to max unless
they are still certified.

scuba tanks can be nasty, I lived in Saudi Arabia for a long time as a kid and they used to fill the tanks at the refinery, one got knocked over or something and the valve was taken clean off, it took off like a rocket parrallel to the ground, went through a couple buildings, through a guys desk and took both legs off just below the knees. He didn't make it. After that they started filling them in a big tank of water. But that said I also was behind my Scuba instructor coming back from a dive racing over dunes and such and the back of his ramcharger files open and tanks spill out every where and nothing, it's hit and miss but you don't want to be there when it hits not sure what this post is all about I'm exhausted and going to bed

[FalcoColumbarius]

So what if you mounted them on the sides of the van with the regulators pointing aftward? That should resolve some acceleration issues.

[Firesong]

Acceleration. Maybe.

Actually the risky part is filling them. That's why they fill them in a water tank.
CO2 tanks are more risky for being unstable in my opinion.
I had a 20oz CO2 tank in the back of my vehicle get a little too warm
and blew the release valve. Talk about a mess accompanied by thumping and
banging. O tanks don't do that. No liquid to expand.

the thread WAS about using CO2 systems to inflate tires instead of air.

just might as well install a compressor, tank, and everything else needed for it then.
my idea (jacpac)was to use a small portable system that could be stored when not in use.

R.A.T.O.!


Those nasty (and not entirely uncommon) tank issues are with cylinders filled to between 2200 and 3300 psi (or 4500 psi for composite SCBA cylinders), and usually involve the cylinder valve. I'm sure if you were only putting a few hundred psi in there, the worst would be just a lot of loud noise... (famous last words?... )
