I am making batches of beer 25 - 35 gallon. The red oxygen tanks are not lasting long enough for me. I am considering purchasing an M80 welders steel oxygen tank with a CGA540 regulator 0-4LPM. Is there any reason to be concerned about contaminating the beer by using a welders steel oxygen tank instead of a stainless steel medical grade oxygen tank?
Don’t see why - CO2 doesn’t come in stainless tanks. That must be frickin expensive too.
I’ve been using a welder’s O2 tank for years.
