Can a dive tank be used for CO2 and be adapted to a air hose?
I can pick up one of these for much less than a power tank.:confused:

Do a search for scuba tank. This was discussed a while back , and if I remember the tank could be used with the right valves.

i have one its sweet- but the high pressure port is not quite enough for a continious 100+ psi needed for air tools -the damn thing will air up 50 tires though- and if needed when you submerg your rig its good for the breathin -hehe:D Jess

I ahve one too, but ahven't converted it to co2 since I use my dive reg to reduce the pressure to 150. You'll need differnt valves, a first stage regular, and about $40 in fittings and lines to amke it work, on top off the tank price. The nice thing about using air in it is that it only costs $2 to fill. Power tanks run about $12 to fill, so a scuba tank would be probably twice that because of the size difference. I can fill up my 37's and a set of 35's from 2 psi to normal operating pressure (20 psi) on one tank.

I just purchased a 10# new cylinder from a local chemical dealer for $90, and a CO2 regulator from a local welding shop for $50 + $10-$15 in hoses and fittings. Same thing as a Pwr tank for 1/2 the price! Also that holder the Pwr tank comes with is just a fire extinguisher bracket.

Just imagine how many tires you could inflate with a scuba tank at 3000 psi. Be a bit like wheeling with a bomb under your seat though. :eek::nuke: :nuke: :nuke:

air in a non condensable so it won't fill up near as much as a co2 tank. co2 in your tank will be in a lliquid form and changes state to a gas when released. mike

So what about converting the scuba tank to CO2? Sounds like the tank is sturdy enough but will they fill it for me?
The scuba tank has a wierd valve on it too. Does it need to be replaced or just adapted?
Thanks guys.:)

I personally wouldn't want to mess with the scuba tank. It just seems like to much trouble dealing with a different valve setup plus what about hydrotest date? When I bought my tank they hydrotested it for me before they could sell it to me and I will not have to get that done for 5 years, plus the fact that any standard compressed gas regulator will fit on it and I use standard fittings available in any hardware/autoparts store.

A welding shop will not fill a scuba tank with CO2.

This may be true but isn't a fire extinguisher shop under the same federal standards as a welding shop? I.E. bottle colored to indicate the type of gas, screw-on saftey cap, so on. I believe this would be true of any "industrial" type shop. While they may do it for you, they could probably be held liable in an accident. Also, at this point you would have had to change to a CO2 or equivilant regulator. Only a scuba shop would be able to fill a scuba valved tank. I don't think the threads in the top of a scuba tank are the same as an industrial gas tank.
