Refill Oxygen tank.
« on: August 26, 2011, 04:07:32 PM »


Being the enviromental concious person that I am I bought this tank for aerating wort so I didn't have to use disposable. I have called about 15 welding shops and I'm not having any luck finding anyone who is able or willing to fill the tank. Does anyone have any suggestions on who might be able to fill it besides welding supply? I don't have a perscription for medical supply stores.

Can't do an exchange for a full one?

Sell it on eBay, and buy a welding tank.

Medical supply stores will need a perscription for an exchange :(. That's also how all the welding supply stores do it. The problem is that this tank is different then there tanks.

Looks like a medical O2 tank. Have you tried exchanging it at a medical supply shop?

I may have too unfortunatly. Welding tanks are a lot more expensive.

Harbor Freight sells new ones for around $80, but most places will only do exchanges anyway so if you can find a cheap used one it won't matter.

Ditched the O2 in favor of a mix stir. Have never looked back.

The welding place near my house said that he could refill my medical tank they just couldn't, "certify it for medical use" - whatever that means. I haven't had the need to try it yet; however, you might try calling them and telling them that you have a medical tank that you are using for homebrewing and see if that changes their tune.

Let us know how this plays out.

How long do you run it and at what speed? Seems like a much cleaner/easier approach than oxygen.

You run it fast for several minutes.  Works fine for ales under 1.060.  For lagers or big beers, one should be aware that the yeast will benefit from more O2 in the beer, so an O2 tank is recommended.  Not saying you can't make beer without O2 in those cases, just what is best practice.

FTR, I've had great fermentations in both lagers and big beers using the Mixstir for aeration.

+1, big beers and lagers benefit from more oxygen than you can get from straight aeration.

Try it! You'll lke it!

P.S. I have heard that others were able to exchange their medical tank for a regular tank.  YMMV

So, it sounds like that by not aerating, I've been skipping a pretty substantial step in my brewing - is this correct?
