Filling Station for C02
This is what a filling station for C02 looks like for paintball tanks. One lever is to allow the c02 gas in from the bulk tank and the other is to fill the actual paintball tank.
You screw the paintball tank into the black end and screw the wheel to press the pin so that you can fill the gas in.
This wears out the pin valve so it’s best to get an on/off valve but of course that costs more.
Bulk paintball batteries are a good way to keep your electronic markers in good shape and powered up for rental customers!
