Whats Better?

[chaos]

Helium

HPA

CO2

these are the 3 types i have narrowed down for the S400 new power source, ill be getting it regulated ect.

my question is what would be the better gas for me.

i would like:

-power
-amount of shots as many as possible
-able to be used for continues shots.

i rate them in the order you posted, helium will give you best performance and the chance to go supersonic

[Insomniac]

Yeah, basically the lighter the gas the better it will shoot. Helium, being the second lightest element is the second best gas to use. Hydrogen will shoot better, but then you have to make sure the chamber has no air left in it because hydrogen is flammable. For power and safety you can't beat helium. Plus you can make your voice sound funny with it

ok so wat about amount of shots? if i had say either Hpa Or He both cylinders of the same capacity....which would yield more shots?

[joannaardway]

Is that capacity mass-wise, or volume-wise?

If you have two 1kg tanks of gas, the helium would last longer.
If you have two 10 litre tanks, they'll last just as long, assuming they're both charged to the same intial pressure.

Helium has the highest flow - it'll fire fastest, and refill faster.
But that also means it will leak out of your chamber and through your valve much more freely than anything else if you have leaks, or you leave it too long. The miniscule particles are very good at escaping... through smaller gaps, and much faster.
Helium is used as an industrial leak testing gas for those reasons.

Thanks that helps alot, i do know that {He} has smaller particles than most other things...(H is only smaller than it) so yer i guess ill test for leaks n stuff wen i get it as well weni get it.
