What is HPA, and Why Does it Matter?

HPA, or High-Pressure Air, is exactly what it sounds like: air that's been compressed to a pressure much higher than the standard 14.7 pounds per square inch (psi) at sea level. In the context of paintball, this means that HPA tanks contain air that's been compressed to much higher levels, typically between 2,000 and 4,500 psi.

The benefits of using HPA are numerous. First and foremost, it provides more consistent performance than CO2. This is because the pressure in an HPA tank remains relatively constant, even as the tank is emptied, whereas the pressure in a CO2 tank decreases as the CO2 is released. As a result, HPA-powered paintball guns are less likely to experience fluctuations in velocity or accuracy.

Secondly, HPA provides better cold-weather performance than CO2. When CO2 is released from a tank, it undergoes a phase change from a liquid to a gas. This phase change absorbs heat, which can cause the gun to become cold and difficult to operate. HPA, on the other hand, does not undergo a phase change when released, so it does not cause the gun to become as cold.

Where Can You Buy HPA Air?

There are a few different places where you can buy HPA air:

• Online retailers: There are a number of online retailers that sell HPA air tanks, as well as the adapters and fittings you need to connect them to your paintball gun. Some popular online retailers include Amazon, eBay, and PaintballGear.com.

• Local paintball shops: Most local paintball shops sell HPA air tanks, as well as the necessary accessories. The advantage of buying from a local paintball shop is that you can get expert advice on which tank is right for you, and you can also have the tank filled on-site.

• Paintball fields: Many paintball fields also sell HPA air tanks and accessories. The advantage of buying from a paintball field is that you can be sure that the tanks are filled with clean, dry air.

How to Choose the Right HPA Tank

When choosing an HPA tank, there are a few things you need to consider:

• Size: HPA tanks come in a variety of sizes, typically ranging from 20 to 90 cubic inches. The size of the tank you need will depend on the type of paintball gun you have and how long you plan on playing.

• Pressure: HPA tanks are typically filled to a pressure of 2,000 to 4,500 psi. The pressure you need will depend on the type of paintball gun you have.

• Material: HPA tanks are typically made from aluminum or carbon fiber. Aluminum tanks are less expensive than carbon fiber tanks, but they are also heavier. Carbon fiber tanks are more expensive than aluminum tanks, but they are also lighter and more durable.

How to Fill an HPA Tank

Once you have purchased an HPA tank, you will need to fill it with air. You can do this at a local paintball shop or at a paintball field. To fill an HPA tank, you will need a fill station. Fill stations are typically equipped with a compressor that will compress the air and a hose that will connect the compressor to the HPA tank.

Conclusion

HPA is a great choice for paintball players who want consistent performance and cold-weather reliability. There are a number of places where you can buy HPA air, including online retailers, local paintball shops, and paintball fields. When choosing an HPA tank, consider the size, pressure, and material of the tank. Once you have purchased an HPA tank, you can fill it at a local paintball shop or at a paintball field.
