Hi everyone,

I am trying to get one CO2 regulator from a friend who works for a beverage company but not the cylinder. Would such regulator can be used? And does it fits with any cylinder such as dry powder fire extinguisher?

Kind help please.
 
If friend works for a bev. co., you can probably get a 5 or 10 or even 20lb liquid CO2 tank from him on the cheap - it will last longer than a fire extinguisher. Also, I don't think fire extinguishers are that easy to adapt to a regulator, whild regulators w/ CGA-320 fittings (for liquid CO2 bottles) are pretty easy to find.

If anything, I'd pursue the CO2 through the friend & get the regulator elsewhere (bev. grade regulators are not the best in terms of quality - a 2 stage regulator is best).
 
Hey Phyroath, You would need to investigate what the thread and fitting types for C02 cylinders are in your country. Beverage regulators can be used. If it all possible get a dual stage regulator. It will have two gauges, a high pressure gauge and low pressure gauge. There are adapters/valves available in the US that adapt dry fire extinguishers to a CGA320. Again that would require more research on your part to find out what the standards are and part availability in your country.
 
Just to point out, two gauges isn't specific to two-stage regulators so if you want to get one of those, make sure it's two-stage.

Everyone talks about how end of tank dump is a problem, but using my one-stage I've never had an issue. At work we only bother using two-stage regulators on GC's and other analytical equipment where constant pressure is a necessity. In those applications, pressure is our concern, not flow rate. If you have a good needle valve, it'll minimize the effects of end of tank dump. And in my opinion, a good needle valve should be much of more of a priority than getting a two-stage regulator.

Ideally, a two-stage reg is nice, but if you don't want to spend the money, it's not too much of a concern.
 
Appreciate you kind advices - Sorry that I absolutely have no idea about this kind of stuff. Here are the specifications with pic:


Made in USA
IMI CORNELIUS INC

- Low pressure gauge 60 psi
- High pressure gauge 1800 psi
- A check valve
- Over pressure relief valve

I would try getting the same beverage cylinder as well however it would look too big. What other fittings besides diffuser I would need? A needle valve, reducing barb, solenoid or just that basic fittings.

Thanks Mgammer, I would try finding the needle valve and the adapter - don't know if I can find locally.
 
I will not go for solenoid but just the needle valve. What are all the correct parts should go for? Any links to good supplier please!
 
You can do both a solenoid & a needle valve if you want.

I'd gather up all collected parts & go see a welding shop or good hardware store and rummage through their fittings until you've got it all working together.

JM - I'd forgotten you're also a lab rat.

If you want to talk to some *really* picky people w/ low flow regulators, go see the guys w/ cell cultures in CO2 incubators.

Also remember - once you've a vague idea what you're after, you can frequently get it cheap on auction sites...(where I got my 2 stage Victor).

If you go w/ a single stage, you just have to replace the bottle as soon as you see it go more than just slightly south of the pressure it was at when you got it... that's when you've run out of liquid CO2 and you're heading for a dump.
