Airgun compressed air

I was thinking about a compressor but I'm concerned about the moisture getting moisture into the gun
What do you guys think about having my local gass store fill up a CO2 tank for me and using this or maybe nitrogen tank?
😳no co2. You bought a Ferrari now you want to put diesel? Get a descent 74 CF carbon fiber tank and have it filled by a dive shop that fills to 4500.

CO2 is a liquid. Your gun will run on nitrogen or compressed air. Nitrogen has a tendency to dry out o rings. Compressed air will be just fine.
 
Air is 78% nitrogen. So you're going to fill it mostly with nitrogen regardless.

Putting in dry air is not a huge mystery, however. I have a second stage of filtration on my YH with the plastic cartridge (inside the aluminum cylinder) filled with color changing dessicant beads. If the beads did not all change color during the fill, the air is dry. If they did, it might be best to vent the tank. I've never had that happen, however. I can fill my 45 minute SCBA tanks at least half a dozen times before I need to change the beads. I got my extra filter and the dessicant from Amazon. There are more expensive ways to do this that I am sure have some advantages but this way is inexpensive, simple, and it works.
