CO2 Bottle Fill Stations

So you're sick of running to your local shop every time you need your bottles filled up, so what options do you have? A CO2 fill station will allow you to fill your CO2 tanks from a much larger bulk CO2 tank. Most of the time the bulk CO2's are 75 pounders that you can get from a welding gas supplier. The bulk CO2 tank must have a dip tube installed in it. The fill station screws right onto the bulk CO2 tank, then your CO2 bottle is attached to a hose and suspended on a scale. The scale is used to measure how much CO2 you have put in the tank. When you first attach your paintball bottle to the station, you must dump all the old CO2 out and zero out the scale. This ensures the bottle is empty and the scale will keep track of how much CO2 you have added to your paintball bottle. It is important to note that CO2 is a liquid that expands when it heats up, so leaving an ounce or two for expansion is recommended.
