Go ahead and give an explanation if you would like.

I really just want to know what's best to use with my new A-5, and I'm sure it will healp others

Cheap, cheap, inexpensive, cheap. Other than that it doesn't require the little additions that CO2 does and I have no experience with N2.

HPA for sure. It holds pressure longer, the fill cost is about the same, its more stable, temp doesnt bother it much, i can use as well in 30 degree weather as in 90 degree weather. Tanks are about double the cost of CO2 but it is worth it. Someone told me you could use N2/Nitrogen in a HPA tank but that is unconfirmed by me yet. I have a 48ci Draxxus air tank that is aluminum and works well, if you have the money, i guess a carbon fiber tank would be lighter but i think the aluminum ones are fine, i got my 48ci 3000psi tank for about 65 bucks so its not too bad.

I use Co2 for now simply because I don't really have the money to buy a good HPA Tank just yet but sooner or later I will get around to it.

Alright, here's the low down:

For all intents and purposes, HPA and N2 act exactly the same. They're interchangeable in the tanks and have no real advantage over one another. The only reason N2 was even used (and it's very rare to find an N2 fill these days) is that N2 is inert while the oxygen and other components in the air we breath aren't. In a atmosphere of pure Nitrogen, it is impossible to make something catch fire. The concerns with early HPA systems and lack of knowledge on the end-user part prompted the industry to initially use N2 to keep any accidents from occurring should someone accidentally put oil into their tank one way or another. With N2, the oil wouldn't do anything under pressure. With HPA, it acts like diesel fuel under pressure and ignites which can cause damage to the tank.

That said, HPA has the advantage over CO2 of not reacting adversely in cold weather. The drop in temperature needed to form liquid N2 or to make some of the gases in HPA liquefy, you'd need immense pressure and temperatures that would freeze you solid almost instantly. This means that you have a constant pressure per volume unit of output. CO2, on the other hand, can be tricky as it takes longer for it to "boil off" when it is cold out, so it can cause issues with poorly engineered markers and wreak havoc on your consistency and velocity. Per volume unit of measure, you get more shots per tank of CO2.

They both have their pluses. They both have their minuses. Just depends on the needs of you and your marker.

HPA, just because it's more consistent and less weather dependent. However, Tippmanns run perfectly fine with CO2, so it's entirely up to you. If you run CO2 with a Palmers Stabilizer (or other CO2 compatible reg), you can get comparable consistency to HPA.

defintely hpa because the a-5s are gas hoggers and with co2 u dont last nearly as long as u do with hpa

And again....


HPA has less energy per unit than CO2. A 68ci/4500psi tank will only get you around 600 shots through an A-5. A 20oz CO2 tank will get you almost as many shots with half the needed volume. This is due to the fact that CO2 can be compressed to a liquid far more readily than HPA (which would precipitate out over a range due to it's multi-elemental makeup).

600? That doesn't sound right... My CPro gets over 1000 easy from a 68/45... are the A5s really that different? I was under the impression the gas efficiency was about the same. Though your right about the CO2/HPA comparison bit.

EDIT: 1000 posts . Didn't notice until I saw 2 stars in my post...

No A5's arent as bad on CO2 and HPA as many people believe it would be.  These guys did some testing and said it finished dead middle which would still give you at least 1000 shots.

I was basing the figure off of the standard CVX valve performance at 70*F and no regulation (850psi input or higher).

I, personally, prefer CO2 with all my Tippmanns.

For whatever reason, I get better performance with CO2. I definitely get more shots per tank with CO2.

From a logical perspective, HPA/N2 would be the better choice. Not affected by weather, faster recharge rate given it's already in gaseous form, etc.   But despite that, I use CO2... and leave my HPA tanks for the Timmy.

I'm using the standard valve with no post-tank downstream regulation... 850 PSI labeled output of the tank...

Same here.  Since I only play in warm weather, CO2 works fine for me.  Plus I have an older A5 (SN 372) that really hates compressed air.

I've always had good results with C02 on my A-5.  I can get a little over half a case of paint on a 20oz bottle.  I switched over to HPA because I tend to play early and late in the season where I don't get as good performance on C02.

compressed air will ALWAYS do better than CO2, you can get them for really cheap on Ebay when people are just trying to get rid of thier guns and throw thier tanks in for "free"
