Kinds Of Paintball Tanks

how to fill paintball tank with air compressor

Paintball tanks are a vital component in paintball. In the game, players shoot each other with paintballs and try to eliminate their opponents from the playing field. It’s played in either an indoor or outdoor area known as a paintball field.

The object of the game is to shoot your opponent with the ball and cover it before they can return fire, which will eliminate you.

Paintballs are gelatin capsules containing primarily polyethylene glycol, along with other non-toxic ingredients like food coloring for coloration. They are designed to break on contact with the skin at a speed too slow to cause damage but fast enough that the player doesn’t have time to react and avoid getting hit.

Paintball tanks come in different sizes depending on how much air pressure you want inside them. Tanks can be used for multiple games at a time or one game. Some tanks are universal and can be used for any kind of paintball gun whereas others are specific to certain guns.

Tanks need to have a specific psi number depending on the type of gun they go with. The average psi range you should have in a tank is between 2,000 to 3,000 psi. You can also choose between carbon fiber or aluminum tanks. Carbon fiber tanks are lighter than aluminum so it will be easier for you to carry your tank around compared to an aluminum one.

Another thing that’s important when choosing a paintball tank is how easy it is to fill. The height of the tank and the opening in which you pour in your air is very important. Some tanks can be filled from the bottom where you unscrew it and some have a pinhole at the top of the tank. The hole types are easier to fill compared to the ones that require you to turn them upside down.

The most common type of paintball tank is a CO2 tank. These tanks have many advantages over compressed air tanks, which include increased shot velocity and reliability for shots at long distances. They do not need to be refilled very often either since they can hold around 2200 psi worth of pressure per cartridge.

There are also HPA (high-pressure air) tanks that use an external compressor to refill them when needed, but these require more maintenance than CO2 vessels because they tend to leak if not properly maintained or repaired after every few hundred rounds fired…

What To Use For Paintball Tank Refill

Paintball tanks are used to store air in compressed form. The most common gas that is used for this purpose is compressed air, which can be obtained from a hand pump or an electric compressor. When the paintball gun is fired, the pressure of the compressed air forces the ball out of the gun’s barrel and towards its target.

As long as there are sufficient quantities of propellant inside it, a paintball tank will continue firing until all ammunition has been expended or until it has been turned off by pulling on its manual valve at minimum 10 times in quick succession – usually with gloves on for safety reasons.

Tank Refill: There are many things you need to know about how to fill up your own paintballs when they run out so that you don’t have to buy more paintballs and spend money. Read on and we’ll tell you how to fill your own tank with fewer hassles and where you can get these items for practically nothing!

Compressed Air

If you plan to use a hand pump, this one’s easy…just go down to the local sporting goods store and pick one up. When using the pump you will need some type of adapter to attach to your paintball tank so that it can fit onto the pump.

There are several different types of adapters and they come in different sizes, so make sure you get an adapter that matches your tank size before inserting it into the air pump.

Compressed Air Source

This item will be used to fill up the tank once you have attached it to the pump. If you plan on refilling your own tanks or if there are several people in your group who do this, then you should consider buying a compressed air “tank” which can be filled by running an extension cord from your car’s cigarette lighter into this container.

You can then regulate the air pressure that comes out of the tank’s nozzle and use it to refill all the tanks in your group.


Whether you’re filling tanks with a hand pump or compressed air, there will be some type of pressure behind the flow and so it is important to protect your hands with some type of glove.

The best type of glove to use is a pair of weightlifting gloves which cover the entire hand and leave no room for air to get in between your fingers…which can be very painful if this happens!


If you plan on filling the tank yourself, you will need one or two rolls of duct tape to tape off the area where you are filling. This will seal any leaks immediately and make sure that no air escapes the tank when it is being filled.


If you plan on refilling tanks yourself, then this one’s for you! If you buy a small 2kg paintball CO2 tank then all you need to do is purchase a small tube of instant cement from the local hardware store and use this to seal up the tank’s valve.

This will make sure that no leaks can occur when you refill your tank at home, making it possible for you to prolong the life of your CO2 tanks significantly.

It should be noted that most people buy 88g or 68g CO2 tanks as they are made of aluminum rather than steel and should never be filled at any paintball field. Doing this will make the tank fail and you could lose your expensive paintballs if this happens, along with other players on the field who may get hurt by flying shrapnel or leakage.

Keep these things in mind and remember that how to fill a paintball tank is simple when you know the right way to do it!

How To Fill Paintball Tank With Air Compressor: A Guide

how to fill paintball tank with air compressor

In this article, we will show you how to fill your paintball tank with an air compressor. It can be done in three steps:

  1. Leave the tank valve open
  2. Attach the air compressor hose to the valve stem and turn it on
  3. Close the tank valve

After these three simple steps, your paintball gun is ready for use! Let’s take a look at what each step entails so that you can prepare yourself before starting.

Step 1: Open Tank Valve

Leave your tank’s valve open so that air can flow into it when using an air compressor. If not, pressure will build up in the gun which could cause injuries or damage if too much pressure builds up inside of it.

Step 2: Attach Air Compressor Hose

Connect the air compressor hose to the paintball marker’s tank valve stem, using an adapter if necessary; this will allow pressure to flow into the gun. After it is connected, turn your air compressor on and ensure that all of its valves are open. Make sure that you are getting the right pressure.

Step 3: Close Tank Valve

When you are happy with the pressure, close your tank’s valve. Congratulations! You have now filled your paintball tank with air using an air compressor.

Safety Tips For Filling Paintball Tanks

The following are some safety tips for filling paintball tanks. As with any other hobby, it is important to be aware of the risks before playing!

The first thing you need to do when filling a tank is making sure that your paintballs are all on the same level. If they’re not then they may break inside the tank and cause an explosion.

When filling your tank, make sure you leave at least one inch of space below the top hatch where air can escape without causing pressure problems in the tank.

This last tip is very important as you don’t want to have unexpected explosions or accidents!

Once everything has been set up correctly, close off both valves on your compressor and start it up again after opening just one valve on your tank. This allows the pressure to equalize gradually.

Some Advice And Warnings

One of the most common mistakes comes from people who fail to follow instructions.

They may have a pressurized tank and a non-pressurized tank mixed up, or they don’t understand that paintball tanks cannot be filled with CO2 because it could cause the propellant to explode. Or they fill the tank too quickly and either don’t put enough oil in or leave too much air in the tank that could cause damage to the internal valves over time.

In addition, research has shown that people who use a tank without first degassing it can experience corrosion inside their regulator as well as increased erosion of internal metal components.

The inside of your newer tanks will be pristine until you start using them regularly and give them a chance to vent the air that’s inside them, which will cause these problems.

If your tank is not degassed before you fill it, either with carbon dioxide or nitrogen, this can cause damage to the internal valves. This damage comes from over-pressurizing the paintball tanks beyond their recommended amount of pressure.

Another reason why people should always check the first fill of the tank and then always degas it before use.

Finally, you should never fill a pressurized paintball tank completely full of paintballs because if the air pressure inside pops the cap off as you fire them down your barrel, those paintballs will likely burst open upon hitting the ground or follow the path of least resistance and just explode inside your marker.

All paintball tanks have a maximum fill limit for the air pressure that is being used to push the paintballs out of your marker. If you put too much pressure on them, they could burst at this point and do some serious damage to either human beings or property.

For example, if you keep filling your tank with paintballs, the pressure could build up until it gets to a point where it can’t be regulated. This is why you need to always check your pressure before you use them properly.

How To Store Your Paintball Tank

how to fill paintball tank with air compressor

Paintball tanks come in a variety of shapes and sizes. But what you might not realize is that there are also different ways to store them. Some people like to store their tank on the side, others prefer it standing up, but for those who play professionally, paintball tanks should always be stored vertically.

The problem with storing your tank horizontally is that the gas inside will slowly leak out over time which can lead to an empty tank when you need it most.

If you have a vertical storage system at home or at work, this isn’t much of an issue because the pressure from gravity will keep the gas inside no matter how long it sits around unused.

But if you don’t have one of these storage systems available then opt for the next best thing. If you keep your tank in an upright position but take it out to use, then depressurize (not de-gas) it before putting it back in storage.

This will prevent any residual or leftover gas from expanding and pushing the valve open while minimizing how much pressure is in the tank when you do need to use it.

If you’re not planning on using your tank anytime soon, then you can de-gas it and store it with the valve open. This practice helps prevent corrosion over time which can shorten the life of your paintball tank or valve assembly.

If this is the route you decide to take make sure that there are no foreign objects hanging around that can puncture or scratch your paintball tank because once it’s been de-gassed, you won’t be able to use it again.

And as always please abide by all local and federal regulations when storing large amounts of compressed gas and always check the pressure on your tank before using it for play or refilling it.

What size of air compressor does a paintball tank require?

Smaller air compressors are usually adequate for filling paintball tanks.

You need an air compressor at least this big to fill your paintball tank: 5 gallons or less, 1/4 hp or less, & 120 volts AC only.

Buying a cheaper model – which is still worthwhile if you’re not playing more than three times per month – but the decision often comes down to personal preference and how often you play.

A high-end unit can fire up faster (certainly handy on game day) and may produce better performance over time; it will also retain its value better should you choose to resell later on.

But these refinements come with corresponding price tags, so make sure you think about what you’ll actually use before purchasing.

Is it safe to use an automotive tire inflator for filling a paintball tank?

Yes, it is safe to use an automotive tire inflator for filling a paintball tank.

They are designed so they won’t produce enough pressure to burst through the thin wall of the air bladder especially if it is thicker than 5mm. 20 PSI should be safe enough unless you drag your car tow hitch on the ground before connecting the air hose.

If you do drag your car tow hitch on the ground first, please remove it before attaching the air hose.

Is the air compressor motor strong enough for a paintball tank?

how to fill paintball tank with air compressor

The air compressor motor is strong enough for a paintball tank.

The airflow rate of these tank fillers is measured in CFM, which stands for Cubic Feet per Minute. This measures how much air can be blown out in one minute with sufficient pressure to match the needs of the particular filling device being used.

The HPA Tanks are usually filled between 180-200 PSI, so each will require at least 10 CFM when using an automotive tire inflator or you’ll need around 30CFM if filling with an AC driven 120-volt pump up unit that goes off the electrical grid without risking overwork on your AC electric motor as it pumps up your paints balls.

It comes down to what equipment you have available as well as your budget.

Can I use an electric pump to fill my paintball tank with compressed air from an outside compressor?

Yes, you can use an electric pump to fill your paintball tank with compressed air from an outside compressor.

To be safe, make sure the electrical requirements of the pump and compressor match and that they are compatible. You may need a step-up or step-down transformer if they don’t match.

Low voltage compressors will barely produce enough pressure for small HPA tanks so it’s recommended to have at least 30 CFM or greater for pumping up HPA tanks below 200 PSI in pressure.

When do you need to refill your compressed air paintball tank?

how to fill paintball tank with air compressor

An air compressor is used to fill a paintball tank. It’s also filled by the on-field air blower, but this will only get players about 15% of their supply for a single game.

Generally, it takes 1 hour for an air compressor to fill a cold cylinder from zero psi up to 180 psi using a manual pump and approximately 30 minutes if done with an electric pump.

If you’re playing more often than three times per month, grind the valves on your paintball gun every 4-6 months which will prolong the life of your compressed tank refill valve or switch out your tanks more often.


If you want to learn how to fill your paintball tank with an air compressor, then the article has provided everything you need. You’ll find that it is easy and quick when done properly. The only thing left for you to do is follow these steps!
