What is the best size CO2 tank for Paintball

Choosing the right size CO2 tank is as important as how we choose a paintball gun. CO2 tanks differ from each other on the basis of weight, CI, PSI, how many shots per fill, etc. Thus, depending on your game mode and preferences you can choose one tank which suits your need.

The answer is: Few popular CO2 tank sizes are 68CI/4500PSI, 50CI/4500PSI, 90CI/4500 PSI and 77CI/4500. However, the best size should be chosen based on the weight, shots per fill, etc of the tank and finally how tall you are.

This post will discuss in detail about different things which you need to keep in mind while choosing a CO2 tank. To make your job easy, we have created a table which clearly differentiates all the CO2 tanks based on their size.

How to use the Paintballic CO2 Tank Table

The above table has 5 coloums which are as below

CI : CI stands for Cubic Inch

The cubic inch (symbol in3) is a unit of measurement for volume in the Imperial units and the United States customary units systems. It is the volume of a cube with each of its three dimensions (length, width, and depth) being one inch long.

Thus, CI is the unit which measures the volume of the CO2 tanks. A tank volume says the maximum quantity of compress liquid CO2 which it can accommodate. As the CI value of a CO2 tank increases its capacity increases.

PSI : stands for Pounds Per Inch

The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 N/m2.

Thus, a PSI value of CO2 tank mentions the maximum pound-force it can withstand. A paintball gun uses compressed CO2 tank to fire the balls out from it. The increase in PSI will gradually increase the range of your marker.

Shots Per Fill:

This column mentions on an average how many paintballs can be fired from that CO2 tank per fill. These values are average values which we determined from huge data we collected. Thus, it may vary between different makers.

Average Weight of Tank:

Every paintball CO2 tanks have its own weight. Since most of the CO2 tanks have to withstand high PSI, it is made from some strong materials. This result in the weight of the tank. The average weight of tank increases with an increase in CI value.

Best for Player Height:

A paintball tank is long and hence it will be difficult for a short person to carry a 100/4500 CO2 tank.

An ideal paintball CO2 tank should stop at elbow’s crease when you hold a paintball marker in your arm. This way you be more comfortable to play.

If you wish to know more about the difference between CO2 and HPA tanks, then I have a detailed post written on this. You can read it here

Three Types of CO2 tanks materials

Currently, CO2 tanks are mostly made from any one of the materials such as – Steel, Carbon Fiber or Aluminum. Thus the material from which the tanks were made will determine its lasting.

Steel Tanks

Basically, you might think that since steel is very strong it will last long. But it is vice-versa, steel has more chance for corrosion and thus prone to easy damage within less period. Thus choose a steel tank only if you can adjust with that.

Aluminum Tanks

As we know Aluminum is one of the lightest material in the earth with respect to its thickness. This the reason it is even used in Airplane manufacturing. Thus aluminum is a good choice for CO2 tanks too which make it easy to carry. The only downside with aluminum CO2 tanks is that it is easily prone to dents as it is light. This decreases its life when compared to carbon fiber tanks.

Carbon Fiber Tanks

Carbon fiber tanks are the most widely used one because it is more durable than Aluminum and steel tanks. Most of the professional players prefer carbon tanks over others. The only downside with carbon fiber tanks is they are more expensive than another one.

Frequently Asked Questions

Is co2 or compressed air better paintball?

Both CO2 and compressed air have its own upside and downsides. CO2 tanks are less expensive but easily affected by outside temperature. Where as compressed air provide high PSI , less effected by outside environment.

How often do paintball tanks need to be hydro?

Most commonly a paintball tank needs to be hydro tested between 3 to 5 years of its purchase. For professional players regular testing is advisable. Every tank comes with an expiration date which can be seen on the back side of it.

Can you fill co2 tanks with compressed air?

Compressed air or Nitrogen needs more PSI than CO2 tanks, thus it is not advisable to fill CO2 tanks with compressed air. However, you can fill HPA tanks with CO2.

Conclusion

As we discussed in this post best size CO2 tank can be chosen depending on your preferences. Few popular CO2 tank sizes are 68CI/4500PSI, 50CI/4500PSI, 90CI/4500 PSI and 77CI/4500. However, the best size should be chosen based on the weight, shots per fill, etc of the tank and finally how tall you are.
