Cheap CO2 regulator

[bigwick]

i am too lazy for taht one.

Its more like $3-5 to fill a 20oz CO2tank

Really for me at a paintball store it costs a dollar.

Well you're lucky then I work at a paintball field and I still pay $2.... Well actually I could fill it myself for free and they wouldn't care, but it's not like $2 is much

I normally use a $200 HPA system though... I have a 68ci 4500 psi tank with a max-flo regulator.... I can regulate 4500 psi from ~300 to .05 with my secondary regulator and air fills are practically free... At the field it's $5 for all-day [compressed] air...(They don't charge you to breathe )... and at home I just fill a large scuba tank at the fire station, so it just cost gas money.

but doesn't co2's liquid characteristics change the gas storing capability's thus making the equation inadequate for the job specified. For example a 20oz co2 canister can hold 20oz's of liquid co2 but **oz of gas :tongue3:

Actually there's not much liquid CO2 in the tank if it is filled correctly. Liquid CO2 damages most guns (even some non-electropneumatic guns), so we are taught to keep it to a minimum in the tanks...

Some CO2 tanks are installed with anti-siphon lines, and some guns are fitted with "X-Chambers" (expansion chambers) so the liquid CO2 doesn't reach the internals of the gun, so there is some in the tank... It varies per fill normally...

You mention using 12gram cartridges, in which case the cheapest way to go is to buy a bicycle tire inflator (Google will help or you local cycle shop). Get one which will take threaded and unthreaded cartridges as you'll have more choice, and you can also use the larger 20grams, and if you've got a couple of extra $$ aim for one with a built in pressure gauge.

They all have very small gas ports so you've got plenty of control over the thing, after all if it rushed in cyclist's tires would explode in their faces, and most have built in regulators, but even without, if you've got a gauge and a slow fill rate you'll be fine. I don't know about where you are but over here I can get one with all of those features for about €10 so at the current exchange rate with the weak dollar that's only maybe $15.

I don't know why more people don't use them.

well maxfreak, beacuse your a cannon noob, it will depend on how big your chamber is. therefore if you find out how big your chaber is in ounces. for example, say your chamber can hold one ounce of air at 1psi, just multiply and youll be able to figure it out

oh, and you're not?

those bike tire inflators would be good for the price, but you have to deal with the single shot aspect.

lowes sells something that would come in handy, I belive it's been posted on this site before.

JSR, you would'nt happen to have the link, would you?

I remember you posting a link to it in another thread

When working with CO2, a blow-out safety valve is almost necessary.... If your reg blows, you have 800-3000 psi rushing in PVC pipe... not good to say at least.

3000psi sounds like someone took a blowtorch to the cylinder

Thanks

schmanman i think your thinking of the kobalt
CO2 Regulator for $90 at lowes

will buy when i need it not a necessity yet.
