Can You Use An Air Compressor To Fill A Paintball Tank?

As a paintball enthusiast, one of the most important things you need is a reliable source of compressed air to power your paintball gun. While paintball tanks require compressed air to function, some paintball players may wonder if they can use an air compressor to fill their paintball tanks instead of buying expensive compressed air tanks.

In this article, we will explore the possibilities and limitations of using an air compressor to fill a paintball tank, and discuss some important terms related to air compressors, paintball tanks, and compressed air.

Equipment Required To Fill A HPA Tank With An Air Compressor

Using an air compressor to fill a paintball tank can be a convenient and cost-effective option for many paintball players. However, it’s important to note that not all air compressors are suitable for filling paintball tanks, as paintball tanks require high-pressure air to function properly.

A standard air compressor used for inflating tires or powering tools may not be able to generate enough pressure to fill a paintball tank.

To fill a paintball tank with an air compressor, you’ll need to make sure you have a high-pressure compressor capable of generating pressures of up to 3,000 psi or more. Additionally, you’ll need a fill station with the appropriate fittings and adapters to connect the air compressor hose to the paintball tank’s fill nipple.

It’s also important to note that paintball tanks require clean, dry air to prevent damage to the regulator seals and prevent moisture from building up inside the tank, so you may need to invest in a moisture filter for your air compressor.

If you’re using an air compressor to fill your paintball tank, it’s important to monitor the pressure inside the tank carefully. Overfilling the tank can damage the regulator seals and prevent air from flowing properly, while underfilling the tank can result in poor performance and inconsistent shots.

To ensure that you’re filling the tank to the correct pressure, you should use a pressure gauge and slowly fill the tank, checking the pressure frequently until you reach the maximum capacity for your tank.

With the right equipment and careful attention to detail, using an air compressor to fill a paintball tank can be a convenient and cost-effective option for paintball players.

How To Fill A Paintball Tank With An Air Compressor

  1. Ensure that the paintball tank you’re using is suitable for compressed air, as some tanks are designed to be used with carbon dioxide (CO2) instead. If your tank is compatible with compressed air, double-check its maximum capacity and pressure rating, as well as any safety guidelines or instructions provided by the manufacturer.
  2. Connect your paintball tank to the air compressor using an air compressor hose. Make sure the connection is secure and that the fill nipple on the tank is aligned with the hose.
  3. Turn on your air compressor and allow it to reach the recommended pressure level for your paintball tank. This information can typically be found on the tank’s label or in the manufacturer’s instructions. Keep an eye on the pressure gauge on the compressor to ensure that the air pressure doesn’t exceed the maximum capacity of your paintball tank.
  4. Slowly open the release valve on your paintball tank to let out any excess air or pressure that may have accumulated inside. This will also help prevent any damage to the regulator seals or other components inside the tank.
  5. Once the release valve is open, slowly fill your paintball tank with compressed air from the air compressor. Again, keep an eye on the pressure gauge on the compressor and the tank’s pressure gauge to ensure that you don’t overfill the tank.
  6. Once the tank is filled to the desired pressure level, turn off the air compressor and disconnect the hose from the tank. Make sure to close the release valve on the tank, as well as any other valves or covers that may be present.
  7. Store your paintball tank in a safe and secure location, such as a tank cover or fabric bag, and make sure to label it with the date of the last hydrostatic test (if required). You’re now ready to use your paintball gun with your newly filled tank!

Safety Equipment Needed

When it comes to filling paintball tanks with an air compressor, safety should be a top priority. The high pressure inside the tanks can be dangerous if proper precautions are not taken. The first piece of safety equipment that you should always use is protective eyewear.

This will help protect your eyes in case of an accident or if the tank ruptures during filling. Additionally, you should wear gloves to protect your hands from frostbite or burns, which can occur if you touch the tank while it’s being filled.

Another important safety measure is to use a hydrostatic test before filling the tank. This test is used to check for any leaks or defects in the tank before it’s filled with compressed air. This will help prevent any potential explosions or accidents that could occur due to a faulty tank.

It’s also important to use a tank cover to protect the tank from any accidental impact or damage. Additionally, be sure to read the manufacturer’s instructions for the tank and compressor to ensure that you are using them safely and correctly.

Types Of Paintball Tanks

There are two main types of paintball tanks: CO2 tanks and compressed air tanks. CO2 tanks are less expensive but have a lower maximum capacity and can be affected by temperature changes.

As CO2 is a liquid in the tank, it must be allowed to vaporize and expand before it can be used in a paintball gun. This can cause issues with consistency and accuracy. However, CO2 tanks are still commonly used by many paintball players due to their affordability.

Compressed air tanks, also known as high-pressure air (HPA) tanks, use compressed air instead of CO2. They are typically more expensive than CO2 tanks, but they offer several advantages. Compressed air tanks can hold more air than CO2 tanks, providing more shots per fill.

They are also not affected by temperature changes and provide more consistent pressure, resulting in more accurate shots. Additionally, compressed air tanks have a longer lifespan than CO2 tanks and do not require as much maintenance. As a result, many experienced paintball players prefer to use compressed air tanks for their paintball guns.

Where Can I Refill My Paintball Air Tank?

There are various places where you can refill your paintball air tank, depending on the type of tank you have. One of the most common places to get your paintball tank refilled is at a paintball field or pro shop. These establishments often have their own air compressor or fill station and can fill up your tank while you wait.

Some paintball fields may even offer free air refills to customers who have purchased a certain package or membership.

If there are no paintball fields or pro shops in your area, you may be able to find other locations that offer air refills. Scuba shops or dive centers often have compressors that can be used to fill paintball tanks, as do some sporting goods stores or gun shops that specialize in airsoft or paintball equipment.

It’s important to call ahead and check if the location offers air refills for paintball tanks and what type of tanks they are equipped to handle. Some locations may only be able to refill certain types of tanks, such as high-pressure air (HPA) tanks or compressed carbon dioxide (CO2) tanks.

Cost Of Refilling Paintball Tank

The cost to fill your paintball tank may vary depending on your location and the type of air you are using. Compressed air tanks are generally cheaper to fill compared to CO2 tanks. The cost to fill a 68 cubic inch compressed air tank could range from $3 to $10, while the cost to fill a 20oz CO2 tank could range from $3 to $5.

Some paintball fields offer free air fills, while others may charge a fee. It’s important to check with your local paintball field or pro shop to determine their pricing and availability.

If you frequently play paintball, it may be more cost-effective to invest in your own air compressor and fill station. This can allow you to fill your own tanks at home, saving you time and money in the long run.

A small air compressor can cost anywhere from $100 to $300, while a high pressure compressor can cost upwards of $3,000. A fill station, which includes a regulator and hoses, can cost around $100 to $200. However, the initial investment may be worth it for avid paintball players who play frequently and require regular air fills.


In conclusion, using an air compressor to fill a paintball tank is possible and can save you time and money. However, it is crucial to follow the necessary safety precautions and ensure you have the correct equipment to avoid any accidents. It’s essential to understand the different types of paintball tanks and their respective fill stations to find the most convenient and affordable option for you.

The cost to fill your tanks will vary depending on your location, the type of tank, and the fill station. It’s always a good idea to call around and compare prices before heading out to refill your tank. Additionally, make sure to have your tank hydrostatically tested regularly to ensure it’s safe to use.
