How to Fill Paintball Tank with Air Compressor

Paintball tanks are required in the sport of paintballing because they provide the necessary force to propel paintballs further. It is propelled by gases such as nitrogen, CO2, or pressurized air. A beginner wants to know how to fill a paintball tank with air compressor.

Before the game starts, you must check the air tank to see if it is filled with compressed air, as your gun will not function if it is empty. If you have a paintball personal air compressor, you can refuel the tank while the game is still going on. It takes a few minutes to completely recharge and be ready to face your opponents.

How to Fill Paintball Tank with Air Compressor

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

Types of Paintball Tanks

HPA, CO2, and nitrogen tanks are the three tank kinds. When choosing a paintball gun, it’s crucial to consider the type of air tank that comes with it. If you purchase it separately, however, you can select whatever you want.


It is known as a “high-pressure air tank,” and it requires extremely compressed air. It is the best-performing tank and the players’ top choice for a variety of reasons. The maximum PSI you can acquire is 5000, and you have a number of options.

Following that is a carbon dioxide tank, which needs carbon dioxide. When the tank is full, it is liquid, and it remains so until you release the trigger. It changes from a liquid to a gas and has enough energy to launch the ball far.

Nitrogen Gas Tank

The third form of tank used in paintball guns is the nitrogen gas tank, which requires only pure nitrogen. These tanks are rarely used and difficult to locate due to a variety of factors, including their high cost and the difficulty of filling the tank with nitrogen.

How to Fill Paintball Tank – The Process

People who are unfamiliar with the game believe that refilling the tank is a difficult and dangerous process, but it is actually a simple and secure procedure. An air compressor is required to replenish the paintball tank.

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?

HPA tanks are more effective than other tank types offered in stores and online. Compressed air is used to launch the paintball over a significant distance. It works perfectly whether it’s hot or cold outside; there’s no change in how it works.

Q: Why are CO2 tanks dependent on weather conditions?

The temperature has a direct influence on it. Temperature has a significant impact on efficiency and effectiveness. It is unsuitable for hot or cold weather and works best in moderate temperatures. Depending on the temperature, the CO2 liquid expands or contracts, which has a significant effect on performance.

Q: What PSI do paintball guns use?

Paintball tanks had pressures ranging from 3000 to 5000 psi. You can choose your favorites from this selection. Tanks with greater PSI ratings generate more force than tanks with lower PSI ratings.


We went over how to fill a paintball tank with an air compressor in great depth. You can simply fill it at home because it only needs to be filled for a short period of time. After reading this article, you’ll understand which tank to purchase based on your skills, budget, and efficiency rating.
