Can i use one to use for kegging purposes?

If so.. how would i go about it?

Yes,

Go buy one and attach the regulator to the top like any other cylinder and go.

I got mine as a rebuilt from the local firefighters, a nice 20 lb cylinder for 70 bucks. My recently aquired 5 lb apparently cost the guys 100 bucks.

One is black the other is red.

There was one on ebay last week.
I'm not a kegger yet though

Stangas, can be done was talking to Neil at Brewmart in Bayswater the other day, he was telling me about a mob in Belmont who supply them etc. Give Neil a call he should have the details.

I've got a 5 kg for sale, with dip tube removed original valve installed pressure tested and filled with co2, regulator fits straight on, ready to go.
Let me know if your interested.

i have "Found" some CO2 Fire Extinguishers already.

Can i just unscrew the nozzle section of the fire extinguisher while it is charged? Or do i have to empty it first?

Who do you get to fill them for you? Most CO2 suppliers in Oz will only fill their own bottles .

Shaun check with your local HBS, mine can fill for you. If not I'm sure they can point you in the right direction locally.

make sure they are in date, ifso any fire extinguisher mob will do it for you.
p.s. dont forget to get the dip tube removed.

Can some one explain the dip tube myth please. Mine has the dip tube in and it is fine

Dogger

Just to throw my two cents worth in,

If your getting them filled by your local extinguisher service, is there any issues with industrial grade CO2 they are using as opposed to the food grade you can get through the major gas suppliers?

If my limited understanding of the subject serves me, it's all about impurities. What are the impurities that are in the industrial grade products, and are there any risks to the average home brewer.

Cheers

Stangas,

Are you asking if you can dispense CO2 from a fire extinguisher, or if you can put your beer in it?

If it's the former, this thread might help http://www.homebrewandbeer.com/forum/vi ... php?t=1273

If it's the latter, I'm not sure, although I wouldn't think you could. It'd probably rust out the insides, depending on what the extinguisher is made of.

Cheers,

Dogger, the dip tube can draw up the co2 in liquid form into the regulator. I say that it can only because you have proven that this is not allways the case. My ones have them removed because i've replaced the trigger handle assembly incuding the dip tube with a regular co2 cylinder shut off valve. The 'o' ring that seals the relief pin when operating the trigger is'nt designed to operate with back pressure therefore I replaced them with a shut off valve.
Industrial vs foodgrade co2 has been a topic on many homebrew forums and have been explained by employers from BOC/Airliquide that it comes from the same source. They say that it would cost more to produce industrial and food grade than just food grade. The only thing is that the cylinders they store the gas in are inspected to a different critera than industrial grade. I too was sceptic on this but many homebrewers all over the world have been kegging with industrial grade co2 without encountering any problems. I guess it's what you feel most comfortable with.

Hillbilly,

Got ya,

yes, my dip tubes are removed if they are part of the extinguisher head

I use industrial grade. Food Grade with gasses is often simply a liscence to add on a few bucks.

Dogger

my question still.. can i take off the head of the extinguisher while the cylinder is charged..

I starting to think not if the dip tube is to be removed.

Anyone?

Good idea if you want a free air trip to Broome. Only safe way you can remove the trigger assembly to be able to remove the dip tube is to fully discharge it. If your goiing that far I'd replace the whole trigger assy with a co2 shut off valve. I would'nt tamper with it myself, leave it to the proffesionals. I believe that if you've opend it up that you should get it pressure tested afterwards to make sure all is safe and that you wont loose any gas, worth the extra couple of dollars in the long run.
Hillbilly.

yeah.. thats what i thought..

i have been talking to a wormald guy from work.. and he stated that the cylinder must be empty first.. and the shut-off valve is a good idea.

that brings my next question, how do you fill the cylinder once the extinguisher has been tampered with?

i was tempted to place the regulator to the extinguisher rubber tubing. That way i am not removing the handle and will make filling a lot easier. Dunno??

Cant do it that way, the hose can't stand the pressure!
