Compressed Air in a Co2 Tank

[Chrishew09]

Does anyone know what the max pressure is for small Co2 tank (under 9oz)? What I was thinking about doing was filling the tank with say 2000psi (or less) of air and using the reg on my marker to regulate it down to the operating pressure of the marker.

This is for a pump, and I know I can buy small tanks for air but they cost money which i dont have a lot of that.

Stick to the 9oz co2 tank and don't even think of putting compressed air in there. It's been done but I believe that tank is not designed for the use of compressed air. If you are using it for a pump you shouldn't have many issues unless it has an auto trigger and you manage to draw that much co2 to freeze the gun or the regulator you have on it isn't co2 friendly.

While I have heard of people putting co2 into a HPA tank I've never heard people doing it the other way. I don't think aco2 burst disk is rated for 2000 psi I think they are only rated to 1800psi.

Of course no field should let you do this anyway since your co2 tank isn't tested for HPA and as such if an unnecessary risk.

If you are putting a HPA tank reg on your co2 tank you might as well buy a small hpa tank as I know they sell for less then fifty bucks without a reg.

yeah butting a reg on a Co2 tank is not cost effective, my local field is doing away with Co2, and switching to air only, that is why i need to run air in my pump. i have to check but i think the burst disc is like 3000psi, but i could be wrong.

Yeah I might have to.

IMHO the minute your field switches to air only they will lose a lot of business. It's still prevalent choice of propelant for spyders and tippmans.

How do you propose to get the HPA into the CO2 tank? Every HPA fill station that I have seen has the femail connector that hooks to the fill nipple on the tank reg, there is no fill nipple on a CO2 tank. Also why do you need HPA for a pump? I have seen pumpers use HPA but never one that felt it was critical to their needs. I would take a few moments to seriously consider what you plan to achieve by doing this and what the possible outcomes may be to what you are proposing.

Well I don't think he is getting ride of it completely but he is switching his rentals to HPA, to save some money on buying Co2.

All you make good points, I think I need to re-asses this whole idea.

Plus you can find 13ci HPA tanks on Action Village for 70 bucks, and a few bigger tanks for a little cheaper. So the prices aren't that bad. You could always switch to 12grams as well or look into getting an extra co2 tank and getting them filled at a place that's not your home field. Which are better options then trying to get HPA into a co2 tank.

Can't you get CO2 filled at Sports Authority? Are you shooting THAT much in a day with a pump?

[Chrishew09]

Yeah, all you guys are right I think i will just break down and get a small HPA.

Thanks guys

1800 psi MAX in co2 tank,

get a 13ci tanks. theyr the size of a 9oz and fil to 3k SAFELY

see dealers forum

The other thing is that your co2 bottle doesn't have a regulator it's a pin valve. So if there is 1800PSI in the tank that is what is going to come out of the tank.

That WILL NOT WORK at ALL!!!! The tanks are designed for about 800 psi, probably tolerate 1200psi for hot days. HPA tanks are engeneered to take higher pressure or else there WOULD NOT BE a different style tank for them. You could fill them with HPA up to 800 PSI and be SAFE only IF you could fill them like traditional co2, but they WILL NOT BE SAFE if you switch the regulators on them. If you fill to 2k you will have a bomb or a rocket!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

WHOA!

The rating on the tank is 1800 psi so that it can safely deal with all but the most extreme pressures from high temperatures. Yes the CO2 may only have 850'ish normally but the tanks were tested at 5/3's of 1800 and certified for 1800 based on that testing. And the tanks don't specify what sort of liquid or gas makes that pressure. So technically and legally you'd be fine to swap out the basic pin valve for a regulator and run the pressure up to a max of 1800 and the reg would hold it down to the 850 normal standard.

But you're right that it would not be safe over the long haul to fill them to 2K.

But with Wevo (and I'm sure a few other outlets) selling 13 and 22 ci 3000 psi tanks why would you bother with all this? You'll need a reg to take the higher pressures regardless and the cost of the tank by itself isn't that much higher than a CO2 tank.
