If you are involved in playing the game of paintball, then you are going to need to have a good tank to use with your paintball gun. With the common companies of paintball air tanks being Gorilla, Energy, Pure, and HPA; however, essentially, all these companies develop three different types of tanks, which are available for use in playing paintball. In order to figure out which one will work best for you, it is important to understand the difference in each type of tank:

1. The 12oz CO2 Paintball Tank. This is actually the most popular size of paintball air tank, more than likely because it is an easy and inexpensive source of gas for your paintball gun. It is available in either steel or aluminum, with the steel construction being a bit heavier, and comes with a push pin valve and a burst disk. Regardless of whether you choose aluminum or steel, you should be able to get around 600+ shots out of this high quality tank.
2. The 16oz CO2 Paintball Tank. This is a rather large size of a CO2 tank. However, it does have the same diameter as that of a 20oz tank and it is also a Catalina quality tank. It is just a little bit shorter in length though and it is also made out of a lighter aluminum construction. With this in mind, you should know that this paintball tank is meant for those who wish to have more CO2 per fill but without having to deal with a bulky tank. If you choose to purchase this tank, you will be able to get around 800+ shots out of its 16oz CO2 tank, which uses a push pin valve and burst disk.
3. The 9oz CO2 Paintball Tank. This is actually the basic size of a paintball tank. If you are not going to be playing a lot and you just want to get a basic gas supply to your paintball gun, and do so at the most inexpensive price possible, then this is the paintball tank that you will want to purchase. Even with these things in mind, you should still know that this paintball tank does come with a strong steel construction, a pushpin valve and a burst disk. With it you can expect to get about 400+ shots.

How to fill paintball air tanks?

When deciding to refill your paintball air tank, you will need two items, which are the high-pressure air fill and high-pressure air cascade tanks. A fare warning, overfilling a compressed a paintball air tank can results in severe injury or death.

1. Release the pressure from the air tank by screwing an adaptor onto the end of the tank until the tank is empty.
2. Confirm the air tank size.
3. Remove the adaptor and close the valve.
4. Place the air tank on a digital scale and zero it out.
5. Connect the supply air tank of liquid CO2 and begin refilling the air tank on the digital scale. When the scale reaches the designated ounce marked on the paintball air tank, stop filling.
6. Turn off the pressure from the supply air tank then release the excess pressure in the line. Unscrew the refill air tank.
7. Done refilling the air tank.

How long does a paintball air tank last?

Even though, it depends on the type of paintball gun and the configuration. A rough estimate for a 48cu/3000psi air tank would be between 500 to 700 shots and for a 68cu/4500psi air tank it would be 1500 to 2000 shot before needing to be refilled.
