How to Fill HPA Tank: 6 Easy Steps and Guide

If you own an HPA tank, the primary issue you face is “How to get it filled?” though there are two methods for doing this. One choice that you can make is to visit the nearest gas station and get your HPA tank filled. But sometimes this choice costs higher and also asks for time and effort. However, the other alternative is to do the job independently after buying a compressor. It will not cost less, but you can do this procedure anytime.

Filling an HPA tank at home requires your attention. In case you don’t know about the procedure. You are at the perfect place. So, let me guide you through and help you out.

What Is an HPA tank?

HPA tank is also known as a High-Pressure Air tank. These tanks are made of hard metal like aluminum, steel, or other helpful material. Mainly, this metal prevents the tank from corrosion, cracks, and leaks, keeping the temperature constant.

These tanks arrive in many sizes, from small to large. HPA tanks can be easily bound on the top of the vehicle. Mainly the size of the tank identifies the going pressure that leads us towards the time limit of current fluid lasting. There is a built-in valve present in the tank. The valve’s primary function is to extract pressure in case the tank gets higher heat or cold. The valve also opens if the pressure inside the tank exceeds the limit.

HPA tanks are mainly used for achieving high accuracy and pressure in paintball. It can store up to 5000PSI.

Types Of HPA Tanks

While filling up the HPA tanks with compressed air, it is vital to check out the material to prevent damage. As for that, you need to look for the construction of an HPA tank to hold the pressure of more than 5000 PSI. Mainly there are three types of HPA tanks:

  • Aluminum Tanks.
  • Fiber Tanks.
  • Steel Tanks.

Out of these three, aluminum HPA tanks are considered the most useful. As aluminum tanks not only uphold the constant pressure but also saves the tank from temperature changes. However, these tanks are heavier, large, durable, and cheaper. But, you also need to remember that these tanks can hold a maximum pressure of 3000 PSI.

Fiber and steals are pricey, but they can hold the pressure for more than 4500 PSI. So, depending on your need. You can go with one.

So, HPA tanks are available as either fiber-wrapped or aluminum types. The fiber-wrapped tanks are designed with carbon fiber formed into cylinders, making them very lightweight and capable of being stored at high pressures. The downfall of these is that they are costly and aren’t so durable, especially when they undergo forceful impacts.

Can I Fill My HPA Tank Through An Air Compressor?

The simple answer to this question is “YES!!”. You can fill your HPA tank with the help of an air compressor. However, there are some precautions that you need to keep in mind before making a move.

Precautions:

  • Ensure to work in the room having air passage and ventilation as you don’t want to obtain smoke or flames during the process. Also, you can’t correctly breathe in a room without air passage.
  • Never overfills the tank. Doing this increase the risk of damage.
  • While filling the tank, don’t put oil or grease on the nozzle. So, this thing can lead the tank to fire.
  • To avoid hazards, try to fill the HPA tank consistently and at a low pace.
  • Notice whether the compressor is ready to bind with a tank or not.
  • Use a safety Burst Disk to avoid extra pressure in the tank while filling.
  • Maintain your tank and notice the hydro date.
  • Switch off the compressor after filling the tank before realizing the air into the environment.

Material Required Filling the HPA Tank Using an Air Compressor

To catch up with the filling process. You firstly need to have the following material:

  • An air compressor: Ensure that the particular air compressor is compatible with your HPA tank. Else, it can damage the tank.
  • Nozzle: To keep up the filling process accessible.
  • HPA Tank: the most critical part of the process.
  • Bleed Valve: This will help you out in realizing the exceeded pressure.
  • An adapter: It will be helpful to combine the tank with the compressor.

Steps for Filling the HPA Tank with Air Compressor

Some basic and easy steps to complete your task (Filling an HPA tank). So, let us see them in detail:

Look For HPA Tank

Before proceeding with the filling process, you should always look for the tank. Notice the material of the tank, and test out for leakages. This step is essential because if your tank has cracks and leaks, you will never be able to achieve the goal. Also, leaks can lead to damage or another hazard. So, repair the tank and then proceed.

Emptying The Tank

Before moving towards the filling step, you need to empty your tank so that there is old air.

Already present in it. You should release it out. While doing this step, ensure to wear a mask and work in the air passage area. This is because the relapsed gas can cause different breathing issues.

Simply use the valve and release the gas slowly. This will never take much time or effort. But will save you from any further damage.

Combining 

Next on the list is the combining part. This is the step when you are finally heading towards the filling. So, join the HPA tank with the air compressor using nozzles. There is a nozzle in the tank and a nozzle in the compressor. To prevent any damage, you need to combine both nozzles perfectly. There should be no air leakage. Use a hose and combine the spacings.

Power The Compressor

After joining the tank to the compressor, you need to power up the air compressor to fill the air. Make sure that your compressor is charged fully. Whether you are using an electric source or battery one to start up, this will never affect the working.

Start filling up the tank and passing the air into the HPA tank. You never need to rush while doing this step. Keep track of timings and notice when the tank is filled. You also need to notice the maximum PSI while doing this step.

Tracking PSI

While filling the tank, keep an eye on the pressure. Notice that maximum air should be available in the tank. This can be done by noticing the PSI unit. Keeping track of PSI will help you judge the pressure in the compressor. This is the time when you can remove the nozzle securely. Before removing the nozzle, ensure to close the valve opening. At this step, the tank is filled with new air.

Store

When it comes to storing the tank, you need to keep in mind to hold it in a secure and close area. If you place the HPA tank on some open surface, there is a risk of damage. So, store the tank in some store in a safe place where there is no reach of pets or children.
