In practice, there's no difference at all, I've used both. Compressed air is about 70% nitrogen anyway. In paintball terms they can be used interchangably.
americans find it easier to get hold of compressed nitrogen whereas we have funny rules regarding compressed nitrogen so its easier for us brits to get compressed air as theres less red tape surrounding it.
if your using a titanium barrel with nitrogen then little sparks come out of the barrel while your shooting. some reaction between titanium and nitrogen apparently
Titanium is a pretty inert metal most times, it forms a few oxides but that's it normally. I'd be most suprised if you get sparks when it is about Nitrogen, Hydrogen maybe at best.
It's one of the reasons a raft of military hardware makers use the damn stuff.
There is a Nitrogen-Titanium reaction at about 800 degrees C, but if you are finding that one, I'm guessing you are shooting a real hot gun
Anyone else heard of this? I'm doubtful currently but willing to learn given the info.
What with Nitrogen being Inert as well as Titanium!!
Nitrogen should be more consistent (slightly) than Air, as it is just one pure gas, whereas, air, is made up of many gases, all having different properties.
Well technically you are spot on the money skeet, but in practice I don't think it'll have any change on the properties of the marker whether you are using Nitrogen pure or an air mix. The pressure ranges we use in paintball are pretty standard across the high pressure industry and are at the low end for applications I've had to tinker with in the past. If the changes in performance between air-nitrogen were THAT serious I'm sure industry standard would have switched over.

I don't know about all this nitrogen/ titanium reaction stuff, but if you get a bit of grit in the barrel, it sparks (in titanium barrels). I always thought it was the same sort of thing as flint being abraded- the sand sparks when it is scratched along the Ti.
