How to Fill Paintball Tank with Air Compressor

Paintball tanks are essential to the sport of paintballing because they supply the necessary force to shoot paintballs farther. It gets its force from gases like nitrogen, CO2, or compressed air. A beginner wants to know how to fill a paintball tank with air compressor.

You must check the air tank before the game begins to see if it is filled with compressed air because your gun will not function if it is empty. If you own a personal air compressor for paintball, you can also refuel the tank while the game is still going on. To fully recharge and be prepared to face off against your opponents, it takes a few minutes.

How to Fill Paintball Tank with Air Compressor

The process of using an air compressor to fill a paintball tank is simple and only takes a few minutes, but before we begin, there are a few other crucial details that we must be aware of.

Types of Paintball Tanks

The three different tank types are HPA, CO2, and nitrogen tanks. When selecting a paintball gun, it’s critical to pay close attention to the type of air tank that’s attached to it. On the other hand, if you’re buying it separately, you can choose whatever you want.


It is referred to as a “high-pressure air tank,” and it needs highly compressed air. Due to a number of factors, it is the best-performing tank and the players’ top pick. The maximum PSI you can obtain is 5000, and you have a variety of options to choose from.


A carbon dioxide tank follows, which requires carbon dioxide. When the tank is full, it is liquid, and it stays liquid up until the moment you pull the trigger. It transforms from a liquid into a gas and has the necessary energy to shoot the ball far.

Nitrogen Gas Tank

The nitrogen gas tank, which needs only pure nitrogen, is the third type of tank used in paintball guns. Due to a number of factors, such as their high cost and the challenge of filling the tank with nitrogen, these tanks are rarely used and are hard to find.

How to Fill Paintball Tank – The Process

People who are unfamiliar with the game refill the tank at stores because they believe it to be a challenging and dangerous process, but it is actually a straightforward and safe procedure. The paintball tank must be refilled using an air compressor.

Following are the things you need to refill the tank

  • Air compressor
  • HPA tank or Co2 tank
  • Gloves
  • Fill adapter
  • Eye protector
  • Hose
  • Scale
  • Safety equipment

The steps required for refilling are as follows.

  • Determine the tank’s type, either HPA or CO2, and then record the PSI.
  • Attaching the nipple is the subsequent step. To make the main nipple available for refilling, locate the O-ring and remove it. With Nipple’s assistance, attach the tank to the air compressor.
  • It is important to note that the transfer process should be slow in order to avoid affecting the filling process.
  • It is advised to fill the tank up to the recommended PSI limit and to maintain the PSI using the gauges.
  • You must let the extra pressure out after the tank is filled because doing so verifies that the filling process is finished.
  • The process must be finished by detaching the hose.

Q: Why are HPA tanks more efficient?

In comparison to other tank types sold in stores and online, HPA tanks are more effective. In order to propel the paintball over a considerable distance, compressed air is used. Whether it’s hot or cold outside, it performs flawlessly; there is no difference in how it functions.

Q: Why are CO2 tanks dependent on weather conditions?

The weather has an absolute impact on it. Efficiency and performance are greatly influenced by temperature. It is unsuitable for hot or cold weather and only performs well in moderate conditions. The CO2 liquid either expands or contracts to depend on the temperature; both cases have a sizable performance impact.

Q: What PSI do paintball guns use?

The pressure in paintball tanks ranged from 3000 psi to 5000 psi. From this list, you can pick your top picks. More force is delivered by tanks with higher PSI ratings than those with lower PSI ratings.


We discussed the process in detail of how to fill a paintball tank with an air compressor. Since it only needs to be filled for a short while, you can easily do it at home. After reading this article, you’ll know which tank to buy based on your abilities, spending limit, and efficiency rating.
