How to Fill a Co2 Tank With Compressed Air
Whether a Co2 tank needs to be refilled for a mechanical system or for playing a friendly game of paintball, the process is simple to do. When filling a Co2 tank, some caution should be used because these tanks can explode when under high pressure. Many Co2 filling stations are equipped with electronic systems which fill the tank to the appropriate point.

1
Inspect the tank visually for any signs of wear and tear, such as cracks. Check the tank for broken O-rings, which prevent air from leaking out of the top of the tank during the filling process. If the tank has some Co2 air remaining, dunk the tank in a bucket of water and see if bubbles run to the top. If so, the tank has a slow leak and should not be filled.

2
Close both ball valves on the filling station. These are the two smaller valves that lead from the filling station to the Co2 adapter hose.

3
Screw the Co2 bottle clockwise into the Co2 air-adapter hose until it is firmly in place. Left-over air from the Co2 bottle might be heard charging out into the filling station, causing the tank to cool down.
-
4
Screw in the Co2 tank's adapter pin depress. Open ball valve two slowly, which is the ball valve that is closest to the Co2 tank being filled.
-
5
Hang the Co2 tank on the digital fish scale. The scale will be used to weigh the tank as it is filled by the filling station.
-
6
Turn on the main valve of the filling station, which allows the air from the filling station's main Co2 chamber to enter into the ball valve's area for filling.
-
7
Turn on ball valve one. Close valve one when the digital scale reads one to 0.5 ounces under the bottle's full capacity. For example, if the bottle weighs nine ounces, only fill the bottle up to eight ounces.
-
8
Close the main valve. Unscrew the Co2 tank's adapter pin depress until it is disengaged completely.
-
9
Open valve two, releasing the remaining air from in the hose. Unscrew the filled Co2 tank.

uhh is it just me or isn't the title misleading? I used CO2 tanks, which are filled mostly with liquid which evaporates into gas which propels the ball. The CO2 tanks are usually around 800 p.s.i. or more. Compressed air on the other hand, is just air squeezed in, these can go from 2000 to 6000 p.s.i waaaay more than a CO2 tank is designed to handle...
