How to fill hpa tank with an air compressorHow to fill hpa tank with an air compressor

The HPA tank is a high-pressure storage device for air. It’s a well-known fact that high-pressure air tanks are becoming more popular in our day-to-day lives. If you want to fill your own HPA tank with an air compressor, the right knowledge must be applied.

Because, if not done properly and in an unsafe manner, you can damage the equipment or worse, injure yourself. The most important thing to remember when filling an HPA tank is to never overfill it.

The following guide is designed to teach you how to fill hpa tank with air compressor without any risks.

Before proceeding with filling the tank, let’s get familiar with the necessary equipment and safety precautions.

How to fill hpa tank with air compressor – ultimate guide

Required materials.    

  • Safety equipment – Safety is the most important thing to consider when filing an HPA tank. Must use Goggles, gloves, and a mask.
  • HPA tank – The tank you are filling
  • Air compressor – The compressor is what supplies the air to the tank. You can use any type of air compressor as long as it meets the necessary requirements.
  • Hose – The hose is responsible for transferring the compressed air from one point to another.
  • Air pressure regulator – It’s a safety device that controls the air pressure when filling up an HPA tank. When filled with air, the regulator will show you what pressure you are at. When it reaches its limit, no more air is entering the tank.

Now that you have all of the necessary materials, it’s time to start filling up the tank.

Check the HPA Tank

Before you do anything, you should check the condition of the tank. Make sure there are no cracks or leaks and that the tank is in good condition.

If you notice any damage, do not continue and contact a professional. Because air can escape from the tank very quickly, it’s important to inspect it for any damage before filling it.

Release Air from the Tank

To refill your HPA tank, first release the air from inside with one quick step. It won’t take much time or effort. To do this, hold the ring on top of a valve with some locking pliers. Turn it counterclockwise until you feel tension, then open up just enough so that air can release from inside your tank.

Note: For your safety, it’s best to use protective glasses while performing this operation. It is essential to release the air in a well-ventilated area. Because it will prevent you from breathing issues.

Connect the Hose to the Air Compressor

After you have released all of the air from the tank, it’s time to connect the hose to the air compressor. The hose must fit snugly onto both the tank and compressor. Make sure there are no leaks and that the hose is tightly attached.

Turn on the compressor

Now that everything is connected, it’s time to turn on the compressor. Make sure the air compressor is in a good condition and has enough power to fill up the tank. Once you have verified that the compressor is working properly, turn it on.

Note: If your air compressor is battery-powered, make sure it’s fully charged before starting this process.

In order to ensure proper filling of air, you will have to keep the right PSI for your HPA tank. If this maximum value doesn’t match what’s needed when inflation begins then things can become very unstable and even dangerous!

Measure the PSI

The next step is to measure the PSI or pounds per square inch. This is important because you need to understand how much air the compressor is putting into the tank. The right PSI needs to be followed when filing your HPA tank because if it’s not properly done, you can damage the equipment.

To avoid this from happening, the tank must be monitored closely while the compressor is filling it. A pressure switch on the air compressor displays the PSI value. You just have to check the PSI.  ​Once you have reached this number, turn off the compressor

When the tank is full, remove the air compressor

Once your HPA tank has reached its maximum PSI limit, turn off the air compressor and disconnect everything from it.

Check the pressure

Before storing your tank, it’s important to check the pressure gauge one last time. Make sure the tank is pressurized and that there are no leaks. If everything looks good, then you can safely store your tank.

Store the tank in a safe place

After you have inspected the HPA tank and made sure it is in good condition. The last thing you want to do when your HPA tank is full is store it in a safe area. Never store your HPA tank in an open area because if the tank falls and breaks, it can create a very dangerous situation.

Types of HPA Tanks

There are two types of HPA tanks: fiber and aluminum.

Fiber HPA tanks are the most popular type of tank on the market. They are strong, durable, and can withstand a lot of wear and tear. They are also lighter than aluminum tanks, which makes them easier to transport.

Aluminum HPA tanks are less common than the fiberglass type. They are heavier than fiberglass tanks, but they are also stronger and more durable. However, they are cheaper than fiberglass.

Checklist for crucial items

We Have created a list of important things you have to consider when filling the HPA tank.

  • Overfilling your tank may damage equipment, so be carefull.
  • While the compressor is filling the tank, keep an eye on it.
  • Before shutting off the compressor, double-check the PSI value.
  • After you have examined the HPA tank, store it in a secure location.
  • Check for any leaks
  • It’s not a good idea to fill an HPA tank inside a house or building. It must be outside where there is adequate ventilation.


Now that you know how to fill an HPA tank with an air compressor, it’s time for you to go out there and do it. This is a simple process but if not done properly or safely, can cause serious damage.

Once everything is ready, make sure to follow all instructions to avoid any negative outcome. Finally, never forget to read the operation manuals for your air compressor and HPA tank.

Through these documents, you can better understand how each system works so you can use it properly without damaging either element.


Can I fill up a paintball tank with an air compressor?

The short answer is No. You can’t just fill your paintball tank with a regular air compressor. For filling paintball air tanks you must have a heavy-duty air compressor. Because a typical compressor produces about 180 PSI, however, a paintball tank must be filled to at least 3000 Pounds Per Square Inch (PSI.

How do I know when my HPA tank is full?

The perfect way to tell if your tank is full of air or needs pumping up, all you have to do is to check the pressure switch on top. The reading will be shown in PSI. If the reading is low, you will need to pump it up.

How long do HPA tanks last?

A properly maintained HPA tank should last for about three to five years. One important thing to remember is that you have to empty it after every use so the tank doesn’t corrode.

Can I overfill my HPA tank?

No! You should never overfill your HPA tank because it can cause the tank to burst. This is a very dangerous situation and should be avoided at all costs.

How to measure the PSI of an air compressor?

The two pressure gauges on air compressors display the PSI levels. One left side gauge shows the tank pressure while the right side one displays the amount of pressure.
