Fill Your Own Dang (CO2) Bottle.

Creating a vacuum inside the tank also creates more volume for CO2 to occupy. The scale is then needed to ensure you do not overfill the tank.

Salute!

What is in the 'empty' tank that you want to pull a vacuum on? I would assume it contains gaseous CO2. If that's the case, why would one want to suck out the remaining CO2 so that more CO2 could be put in?

Here is a picture how I fill my small Co2 tanks. I just made a holder for a 20lb tank upside down and information from some paint ballers. Works great shot of co2 and dump gets the tanks cold open fill valve and watch scale.

Hope this helps

Not that I'm planning on a keg setup, but do any of you convert CO2 fire extinguishers as your gas bottles? Seems like it would work fine, and might be cheaper at certain phases of the market.<edit> - then again, probably all the threads are different and nothing matches up. Nevermind </edit>

my old boss used to convert them and sell em. its the same 20# bottle and valve. but can be tricky to get filled. airgas has tightened their sphinkter over the years.
