I don't know much about fire extinguisher, but I think the fittings is different, and there is siphon in the CO2 FE,I'm confused, can you use a CO2 fire extinguisher for CO2? Or is it a different fitting or something?
i have seen many and had a few , the ones ive seen dont look anything like regular co2 tanks we buyyes, you can use it.. but only CO2 fire extinguishers.
and only after you take it to a CO2 charging spot, so they can change the lever, with a regular co2 tap..
how do you think they make the co2 based fire extiguishers? it's just a regular co2 bottle with a different tap..
i think the bottles look exactly the same, except the red paint of course.i have seen many and had a few , the ones ive seen dont look anything like regular co2 tanks we buy
However, this isn't taken for granted. Throughout the world you can read of people who have replaced valves on fire extinguishers with cga 320 on/off valves.Some people may have missed the location. fishygurl is in Victoria, B.C.
Some, of what most of us might take for granted, isn't necessarily so in other countries, even as close as Canada or Mexico.
Good to know, thanks! I can find a different one, I just wanted to know as the place that sells fire extinguishers is the place where most people around here get them refilled.However, this isn't taken for granted.

You need to have a fire shop or gas/welding shop do it. In locations like the UK, it is relatively common due to the price of co2 tanks.
I have read of people doing this in the UK, Australia and canada.
In canada it is likely you can get a co2 tank for a reasonable price, comparable to what it would cost to buy/convert an extinguisher.
some people go to fire extinguisher shops, others go to somewhere like boc gas or arigas, personally i go to a beer distributer bc they fill while i wait.Good to know, thanks!

i think the snow has a lot to do with the black funnel thing attached to the outlet, i think they suck air in and the turbulance and air mixed with freezing co2 makes snowNot so on the UK/Euopean Co2 extinguishers they are pressurised vessels only(pressurised to 1000Psi when full) basicly a big paintball tank for all intensive pourposes.
The "snow" is caused by the rapid change in pressure causing extreme temprature difference (one reason why you dont hold the horn on a Co2 extinguisher)
Try opening the valve on a Co2 cylinder (if you can hold on to it !! they pack a punch) you will get "snow" around the valve nozzel.
Nice. Now you got me wanting to go buy one and play with it.i think the snow has a lot to do with the black funnel thing attached to the outlet, i think they suck air in and the turbulance and air mixed with freezing co2 makes snow![]()
i used to play with old extinguishers when the mall near me closed down. those yellow dust ones are nasty. dont shoot one of them off in a small space, and stand up wind.Nice. Now you got me wanting to go buy one and play with it.
The funnel helps direct the gas cloud to the flames. At the narrow end of the inside of the funnel there is a six jet nozzel to disperse the gas along the edges of the inside of the funnel. The snow or frost only lasts a few second and is formed on the metal of the nozzel and the outside of the funnel and connecting pipe (if you hold these areas while operating the extinguisher you will suffer a freeze burn or lose some skin).i think the snow has a lot to do with the black funnel thing attached to the outlet, i think they suck air in and the turbulance and air mixed with freezing co2 makes snow![]()
isent there some sort of "venturi" openings in the narrow part of the funnel?The funnel helps direct the gas cloud to the flames.

That is the new design funnel it has a double skinned wall (old type was single wall) to prevent the user from freeze burn should they accidently hold the funnel (you'd be surprised how many are tempted to do it) but for training everyone is told to not hold the funnel (FE have a long shelf life (10 years) if serviced regularly before they are re pressure tested)isent there some sort of "venturi" openings in the narrow part of the funnel?
