CO2 Tanks for Paintball Gun Guide: Everything You Need to Know

CO2 tanks are an essential part of any paintball gun, providing the power necessary to operate the gun and propel the paint from the paintball marker. Here are a few things you need to know about CO2 tanks before purchasing one.

Tank size

First, you need to determine the size of the air tank you need. Your gun type determines the tank size. Also, consider how often you plan on using it. A larger tank will be more expensive, but it will also last longer before needing to be refilled (read more: how long do paintball tanks last?).

Tanks come in a variety of sizes. Here are some paintball air tank sizes:

  • The smallest tanks are 0.2 liters, 175 mm long, and 61 mm wide
  • 0.30 liter tanks are 215 mm long and 61 mm wide
  • 0.35 liter tanks are 260 mm long and 61 mm wide
  • 0.45 liter tanks are 310 mm long and 61 mm wide.
  • In the United States, 20 oz tanks are also popular, which is roughly 0.59 liter (591.47 milliliters)

Valve System

Next, you must decide what valve system you want on your tank. There are two basic types: pin valve and screw-in valve. Pin valves are the most common and are typically less expensive, but they can be more difficult to refill. Screw-in valves are easier to refill, but they are more expensive.


Finally, think about what brand of CO2 tank you want to buy. Many different brands are available, so research to find one that is compatible with your gun and has a good reputation.

There are many popular brands of paintball CO2 tanks, such as:

  • Empire
  • Tippmann
  • Dye
  • GOG
  • Ninja

These brands offer high-quality CO2 tanks that give you the best possible performance while playing paintball.

How to put an air tank on a paintball gun

To put an air tank on a paintball gun, you will need to find the right size and type of adapter for your gun. Once you have found the correct adapter, you will need to screw it onto the bottom of the air tank. After the adapter is securely in place, you will need to screw the air tank into the adapter. Ensure the air tank is closed tight without leaks.

How much pressure can co2 paintball tanks hold?

Always check the listed psi (pressure per inch) from the manufacturer before you fill your tank with high-pressure air. Most paintball tanks can hold up to 300 bar of pressure, or 4351 psi (pressure per inch)

How to empty a paintball co2 tank

To empty a paintball co2 tank, you need to release the gas from the tank by unscrewing the valve at the top. Once the gas is released, you can then unscrew the tank from the marker and remove it from play.

Types of CO2 canisters for paintball guns

There are two CO2 canisters for paintball guns: disposable and refillable. Disposable canisters are more affordable, but you replace them after each use. Refillable canisters are more costly, but you can use them multiple times.

Paintball guns with co2 tank

Paintball guns that use co2 tanks are some of the most popular on the market. They are known for their accuracy and power, and that’s why professional paintball players use them. Co2 tanks are also very affordable, making them an excellent option for beginner and intermediate players.

Other than co2, some guns use HPA (compressed air) or nitrogen.

Where can I get co2 for my paintball gun?

The best thing to do is to join a Facebook group about paintball in your area and ask other players where they fill co2 (read more: how to fill a paintball tank).

There are a few places to get CO2 for your paintball gun: You can buy it at a paintball store, a paintball field, welding tool stores, stores that sell or fill fire extinguishers, beer brew or home brew shops, shops that sell SodaStream, scuba diving shops, and sporting stores that sell paintball equipment. You may be lucky at local gas stations if the owner has set up a CO2 refill station.

How much are co2 tanks for paintball guns

Paintball CO2 tanks typically range in price from $30 to $60, depending on the tank size.

How much does it cost to fill co2 on a paintball air tank?

The cost to fill a paintball air tank with CO2 will vary depending on the size of the tank and where you go. A small tank may cost around $5 to fill, while a larger tank could cost $10 or more. You can typically find places to fill your tank at sporting goods stores, paintball shops, or gas stations.

How does the co2 injection system for paintball tanks work?

A CO2 injection system for paintball tanks works by injecting CO2 into the paintball gun’s chamber. This high-pressure CO2 propels the paintballs through the gun and out of the barrel. The amount of CO2 injected into the gun will determine how fast the paintballs shoot.

How to fill CO2 and HPA tanks at home

To fill your CO2 and HPA tanks for paintball at home, you will need a few things:

  1. A CO2 or HPA tank.
  2. A fill station of CO2 or HPA (compressed air).
  3. An adapter to connect the fill station to your tank.

To begin, connect your adapter to the fill station. Then, open the valve on your tank and slowly screw it onto the fill station. Once the tank is secure, open the valve on the fill station and allow CO2 or HPA to flow into your tank. Fill the tank until it is full, then close the valve on the fill station and remove your tank (read more: compressed air pump for paintball).
