only at freezing your internals. Get HPA...you'll thank us for it.

yeah well unfortunately, there isnt anywhere to get HPA where i live, just co2 and air, but i am pretty sure co2 is the definite choice.. right?

wait. are you filling your CO2 tank with compressed air?

HE couldn't be, stick with co2 says I, its cheap, and easily got.

HPA = air

Yes HPA stands for High Pressure Air. Hpa is ALOT better then co2. Co2 is very dirty and changes from a gas to a liquid very quickly. Liquid co2 in your gun can cause the internals of the gun to freeze up, and just plain is coooollldddd, While using air is alot cleaner for the gun. Once you use compressed air you will never go back to co2. So get the air and you wont regret it.

shouldn't this have been in a different section? like air systems?

its a general question, so its fine here. there are threads here about tanks all the time.

right
but the problem is i fillled my tank with compressed ait. hpa. last weeekend. and i have a 20 oz. i could only get about 450 shots tops off it! i was told that if i fill up my 20z with co2, i could get 1000 shots off it

:eek: You acctually put hpa in a co2 tanK!? Madness! I think whoever filled your tank was either lieing to you or was insane.

you cant put compressed air into a co2 tank, Hpa tanks use a fill nipple where a co2 just goes in through the pin valve.

well wtf i definetly have a 20 oz co2 tank. I took it to a diving shop where it was filled with compressed air.

I have heard rumors about filling CO2 tanks with compressed air...sounds strange to me, but it just might be possible.....???

I am also in the stage of looking at HPA. Way more expensive than I first thought. How do you know what to get? There are different types of PSI tanks. I have seen from $99 to about $400!!!

it might be possible to fill it up .. but your gonna kill yourself or someone else over time .... USE CO2 OR GET A HPA TANK !!!!

get anti-siphoned tank too .. it'll help a lot .. as well as a reg .. adjustable = good .. LP setups are also ... something you should have although it isn't needed ... lp = less kick and better efficiency ..

shens...period. The HPA can't hook up to a threaded valve, only to a fill nipple...and if he modded the valve to accept it, he's more ignorant than needs to be. It's unsafe and sets a bad example to the younger crowd in this forum.
Post a video of you filling the co2 tank with a compressor and I'll retract everything I've said...until then...shens.


but it's still unsafe....

Post a pic of your tank......it is possible......however a CO2 tank is only rated to 1800 PSI which won't get you many shots. Also to fill the tank they would have had to put a reg on your CO2 bottle......or you could do it a couple other ways but it isn't easy!

I will call you an outright liar because a scuba shop owner or employee would know better than to do so not to mention the extreme danger of attempting such a task. As stated, they are filled in a different manner anyways -

On another note, were you aware that giving our false or deceptive information on these forums are a bannable offense? Think before you post here - :rolleyes:

As others mentioned, while this is possible it's rather unlikely.

You or the shop would needed special fittings that no one normally has a use for.

The tank could only have been filled to ~1500 psi...much more and you'd have blown your burst disk (unless, god help you, some moron installed a higher pressure burst disk and risked turning your tank into a fragmentation 'nade or missile.

So...you had a 20oz tank with ~1500 psi of air. I'm supprised you got as many shots as you did.

Fill it with co2 and you'll get over 1k shots easy (I did a hopper shy of 1500 shots last weekend on my 20oz tank).

just wondering.... even if it was possible wouldn't the burst disk go before the tank would fill? I would think the burst disk for a HPA tank is much higher than on a C02 tank, and therefore would pop as they were filling it.

I don't think you could fill a Co2 bottle slow enough. That much pressure - upwards of 3000-5000 psi being released into a tank like that (at any speed) would instantly blow the burst disk.

I call shens as well, and agree with what Dragon and everyone else said.

wow...i never knew, but there didnt seem to be any problem with filling it with air except for the lack of shots. Im definetly not paying that much for a hpa tank... i think i ll just use co2 ;)

actually i have seen a 20oz bottle with a nitro reg on it. it's a 14ci 3000 i believe... it's used mainly on stock class pumps... i can't remeber the site but if you do a search for it you could possibly find it.

druid
05-05-2006, 02:50 PM
Wevo has them and they are HPA only...NOT CO2. Any certified airsmith or even a moderately observant PT field-filler worth his spit, knows the difference. HPA have side-mounted fill nipples...CO2 doesn't.

a c02 tank will never withstand 3000 psi, physically or legally. changing the reg doesnt change the safety regulations. also, a "stock class" gun can't use constant air. constant air pump is "modified class" i believe.

14 ci tanks are alot smaller than 20 oz co2 tanks. they are completely different

Sorry, just getting a picture of the tanks - forgive the price (I don't feel like editing tonight...)

Here's what the smaller HPA tanks look like - guess they do look like small Co2 tanks, except for the fill nipple on the side of the reg. There's a big difference though.

Your welcome, and it's entirely possible that someone MAY have put a reg on a 20 oz tank. However, I don't think these are close in size to a 20 oz tank. I really hope that didn't happen, by the way, because I'd almost bet that the tank walls themselves are either thicker, or made of a different material to withstand the pressure, whereas a Co2 tank wouldn't be safe at all!

actually a dive shop would probably have the right fitting to fill a threaded tank due to the fact that SCOTT airpacks are filled with a threaded valve, as are bulk airtanks, it is just REALLY REALLY UNSAFE to put air at full pressure into a Co2 tank.

i never said there couldnt be something that LOOKED like it, i merely stated that an actual c02 tank would not withstand the pressure.

I gotta say........that isn't entirely true! If you use a Nitrogen/HPA reg you can dial it to whatever you want. 1800 Psi is easy enough. On to will it withstand 3000 psi. Well they are rated to 1800......they are generally tested to well over 3000 when hydroed. I however would seriously warn anyone read this not to surpass 1800 psi in a CO2 tank. As far as the smaller air tanks go.....I happen to have one, White Wolf Airsmithing sells them in various sizes. They are the width of a 9-12 oz tank. Lenght varies depending on size. I have also seen several CO2 tanks with regs on them. I always advise that they are removed. Completely useless on CO2. I'll have to go look at our firefighters tanks. We have a few older ones that we revamped for paintball with a reg.

To the original poster a pic would help.......but I'd only use CO2 in that tank!

I stand corrected. I was thinking of how we do it here. Our nitro tanks don't have a reg, we just crack it open carefully - of course we've done it for so long, we know exactly how much to do it so it doesn't kill us!

timbertiger20
05-07-2006, 02:07 AM
Yeah, that's how we do it normally. But if we get a tank over 6000-10000k we use a reg!
