Air Tanks

I have two small oxygen ( medical style 2.5' tall 4" dia.) bottles and wondered if they would hold air for jeep on trips. What kind of pressure they can withstand. feels like Aluminum.

 

Check the numbers stamped around the shoulder of the tank, they are codes for the material, the pressure and volume, and the testing dates. A medical supply outlet could interpret these for you. Be aware, in some states medical Oxygen is considered a controlled substance. Dumb, but true.

They are likely to be 2015 psi. and hold something like 15 ("D"size) to 25 ("E" size) cubic feet of air at that pressure.

To use them for tire air you would need (1), someone to filll them to high pressure, such as a scuba or paintball shop, and (2), a regulator to reduce the output pressure to 100 psi or so for use.

Note that high pressure cylinders need regular (annual) DOT approved testing and certification to be refilled or transported legally and safely. These kinds of tank pressures are no joke, they are potential bombs.

I think you'd find it a lot of trouble, unless you have a friend with a HP compressor.

I dont deal with medical oxygen, but I do deal daily with SCBAs and nitrogen. Legally, nitrogen bottles have to be tested every 5 years, SCBA bottles every 3. Having them filled would be a pain, a shop that has the capabilities to fill them wouldnt do it most likely. They wont put anything but oxygen back in and do you really want to fill up your tires with that? Sounds like an expensive fill up to me. You might be able to change the valves and make it a nice little set of torch bottles though.

 

How about turning them into tanks under your jeep and have a 12 volt compresser fill them and use that as air storage!

 

Thanks for your Ideas. didnt know if worth doing
thanks

 

something is better then nothing for air.. better then right off the compresser..
