[quote=“SodaEnthusiast11”][quote=“Radagast”]When I got mine, I went to the local Airgas shop and spoke to someone there. They did not refill tanks at that location but he was able to direct me to a welding/gas company that would. Or you could do this
Thanks for the reply, Radagast.
I also e-mailed a few companies and I got back one response so far that I thought I would share here in case anyone else is interested.
Toll Gas in Plymouth MN will fill a 5 pound CO2 tank provided that it has the correct PSI valve (CGA 320) for $24.71 including tax, any time Monday-Friday after 10:30 AM. They say that you can also drop it off and pick it up later or alternatively they will let you exchange it for a tank that has already been filled.
This is the CO2 Tank that I purchased:
EDIT: I got a few more details regarding which types of tanks they will fill. They say that the test pressure must be correct for the service pressure. For a 1800psi tank the test pressure must be 3000psi (as stamped on the safety valve). If you bring in a tank with a service pressure of 2015psi and a test pressure 3000psi they will not fill it because the test pressure is wrong (should be 3360psi for a 2015psi tank).[/quote]
$24.71 seems pretty high for a five pound tank. I exchange mine for $14 and change locally. Like you, I bought a new tank initially and agonized over giving it up for a well used exchange tank. In the end, I just walk in to the local welding supply shop, hand them an empty tank, and walk out with a prefilled one. They send them out to refill them, and it’s quicker than standing in line to just grab a full one and go, anyway.
