Title: A question on air that we use for our pcps
Post by: Marno on April 08, 2017, 05:29:13 PM
Hey guys, i just want to find out can nitrogen(dry air) be used to fill our pcp air rifles?

Yes but why bother. Air is 80% nitrogen and must be cheaper than an industrial gas.

absolutely, nitrogen is clean, dry air.......just what your gun thrives on. You have a great air gun enjoy it and don't worry about using nitrogen. My shooting buddy has used nitrogen for years with no ill effects.

I used N2 for a while as a backup for when the paintball shop that usually filled my tanks was not available.  It's actually pretty inexpensive if you don't use medical grade N2.  I rented a 444 CF 6000 psi tank from a welding company for $8 per month.  I only had to exchange the depleted (3200 psi) tank with a full tank twice in a year @ $44 each time.

Thanks guys, could anyone see a difference in shot count?

Personally I've never used nitrogen but I would imagine it's close to being the same as compressed air if not exactly the same.

I didn't notice anything different.  After all it's almost the same as HPA.  The pressure is what counts.

Yes but nitrogen is more consistent, isint it?

Now you are splitting hairs I think. Yes its consistent in composition, but it doesnt matter anything, you have so many variables in an airgun anyways.
Air or nitrogen doesnt really matter much if all. Put helium in the mix and things start to get different.

Please explain why? I would like to know

Dry air vs dry nitrogen and you cant see any diffrence. Helium in the other hand is lighter that air and has smaller molecules so it flows a quite bit faster.
There is lot of talk about helium in the forum if you are interested.
