compressed air in co2 tanks

[jwa158]

i read in the forums earlier saying that you can use compressed air in co2 tanks? and somethign about co2 eatin up the walls or something on the inside. what if you bought a new co2 tank and used compressed air? could you use the same valve or whatever or do you have to get a new one?

Um.. no.

It is possible to haev CO2 in a N2 tank as long as you have a co2 valve in the tank.

But hte other way around is not true. I am pretty sure normal co2 valves are not rated for 3k-4.5k and I wouldn't trust hte actualy structure either.

CO2 BOTTLES ARE ONLY RATED FOR ABOUT 1600 PSI!

Be careful... don't try to fill it with 3000 PSI of compressed air. Thank god for the invention of burst discs... as I have heard of people finding this out the HARD way. :D

actually its 1800 psi, but it still isnt a good idea (nor is it legal).

i rember this company putting out an inline reg, with fill adapter to fill your co2 tanks to 1800 psi. i wonder what happened to them.

i also rember that pro's used to put a little co2 in their nitrogen tanks, that way their tanks never dropped below 800 psi for a while.

ahh the good old days.
