HPA/NITRO/COMPRESSED AIR vs. CO2

[Jack & Coke]

[Kallahan]

CO2 is not an ideal gas, it does not behave in relativly predictable ways, while HPA is. If you take a certain mass of air, and put it in a certain volume, at a certain temperature, you can relativly easly figure out what kind of presure it is exerting. CO2 however, you have to worry about wether it is turning to liquid or solid because of its wierd boiling/melting points, Solid CO2 (dry ice) is so weird that at room temp it changes directly from a solid to a gas, it's liquid form is seen only under pressure.

While CO2 can get more shots off a tank due to it being a dense liquid under pressure, that change from liquid to gas doesn't allow for the ideal gas laws to predict its attributes accuratly. HPA doesn't have this problem, it takes extreme pressure to turn the mostly nitrogen/oxygen mixture of air into a liquid, far more pressure than any painball or scuba tank can withstand, thus no change from liquid to gas and the ideal gas laws apply all of the time. Which allows for far greater consistancy, and much faster recharge time.

I've yet to find HPA 12grams so.. I guess I have to say C02.

Woohoo!

7 shots off a HPA 12-gram!

This is interesting - almost comparable to the diesel gas debate. Diesel has a lot of things going for it, but gas is used because it is easier.

This CO2 not working predictably I don't think is accurate. I think its more an inability to predict. I mean CO2 is always CO2, it should perform in the same predicatable manner if we consider all outside variables. Perhaps its time to design a marker / reg / expansion chamber combo with today's technology to fire CO2 specifically. Maybe its possible to use it in liquid form better? Unfortunatly I do not have the mechanical knowledg to really get into how it would be done to get much further than that.

But CO2 does have some good things going for it. When you get CO2 you are getting 99.99% CO2. When you are getting compressed air you are getting a variable of whatever is in the air in that area. Is it possible that "polluted" HPA could perform oddly.

I would think because CO2 has less variables in composition it may be possible to make a system designed to work of CO2 that would be more stable in velocity than HPA.

You make it sound as though CO2 is totally unquanitfiable, which is a total load.

It is entirely possible to know what CO2 is going to do at any given state point inside a system.

It is precisely predictable, maybe not by you, but it is possible.

Just because you don't understand it, do not make the assumption that no one does.

The whole recharge argument is BS too. If you are talking about solid CO2, verses HPA at tank pressure, then there will be a big difference. Otherwise, not so much.

In normal play, with a CO2 system functioning correctly, you will see no difference in performance. If you do, then your system is not set up properly, or you are using a mag or older Angel. Simple as that.

EDIT: Now, that is not to say that HPA isn't markedly easier to set up on most markers. But Easier /= Better However, even the worst set up HPA system will be better than a poorly set up CO2 system. IE CO2 isn't idiot proof, and while HPA is not totally idiot proof, it is much less demanding that CO2, and therefore easier to get right.

Last I checked, most NEW Co2 tanks are more than that. The tanks that are less than $25 usually aren't worth it IMO.

What could you possibly mean by that?

I like my Co2, from what I hear HPA is hard to come by where Im from... I play rec woods all day.. so I pack a couple CO2 tanks... I get more shots than with HPA, can carry more tanks and its cheaper. The only time it becomes a problem is during the colder months.. thats when I bring out the stock tippy 98 (not custom) and co2 problems solved. In the summer the temp. gets up in the 80's and 90's at times, so co2 problems are non existent. In the event the temp is lower, I have my palmers stab.

palmers stab + 2 20 oz tanks > 68ci 3000 psi (approximate price comparison)
