Scuba tank?
 
hey guys, I know a lot of people use various tanks and compressors to inflate on the trail. I have a 3000 psi scuba tank and want to use it for this purpose.

Anyone use one? how many tires can I fill off of this?

you can definatly use it...

the amount of tires you can fill will depend on the size of the scuba tank and the pressure you fill it to.

if you had onboard air you could fill an unlimited number of tires.

if you actually had it filled @ a scuba place to 3000 psi and could somehow use it with a regulator and air chuck you could fill more tires than i could imagine you would ever need to at a given time.

if you filled it to 150psi or so (normal pressure for an air tank) i can't see you filling more than a couple 33's or so....

i'd probably pass on it myself.....

cool. its a 80cu in @ 3000psi. I have a fill station I used for paintball that has a bleed off. i was thinking of running an air line/chuck off of it. would a reg be necessary? i can controll the air flow by the valve knob.

i'd put a regulator on it. you don't wanna infalte your tires too quickly, and it would be nice to also see how much pressure is left in the tank. anyone know how much used scuba tanks go for nowadays?

got mine for $60 on ebay. my company does hydrotesting so i had it serviced for nothing.

Fills are $5.

You will have to fill that tank yourself and not a dive shop after a while. They must be inspected every 5 years. I have used my tanks for just this purpose with an inflater valve purchased at a local dive shop. You will need a reg. unless you are good with the valve because they can flow a lot of air very fast!

My company does the hydros. what reg do i need?

Don't do it.

Scuba tanks are very strong. Valves, however, aren't. They are made of brass and chrome plated. It doesn't take much to damage or worse break the valve.

You don't want a loaded tank taking off inside your jump should the valve get loose.

What Jeff said. A 3000 psi tank in a car accident is basically a bomb that might explode.

On the other hand if you had a used SCUBA tank and only filled it to a few hundred psi you would probably be good.

Check out small welding tanks. They are DOT rated and will hold 2000+ psi. My plan is one of these mounted somewhere out of the way, filled with nitrogen. Regulate it down to 100 psi and inflate tires or run air tools off of it.

Bubba Ray 07-17-2007 04:07 PM

Just get a cheap reg and fill to 1500psi then strap it down good.
