If you’re a paintball enthusiast, you may have wondered at some point whether you can use compressed air in a CO2 paintball gun. The answer to this question is yes – you can use compressed air in a CO2 paintball gun, but there are some things you need to know before doing so. In this article, we will discuss the pros and cons of using compressed air in a CO2 paintball gun and give you some tips on how to do it safely.
Concerns With Filling A CO2 Tank With Compressed Air
Compressed air, also known as HPA (high-pressure air), is pressurized to a much higher level than CO2 and can cause damage to your paintball gun over time. This increased pressure can lead to more wear on internal components of the gun, such as seals and o-rings, leading to frequent breakage or malfunctioning. Additionally, if your paintball gun was originally designed for use with CO2 only, it may not be able to handle the higher pressures associated with compressed air tanks. Before using a compressed air tank in your CO2 paintball gun, make sure you consult the manufacturer’s instructions. 
Using a compressed air tank in a CO2 paintball gun can also lead to safety issues, as it increases the risk of the tank exploding. When using a compressed air tank with your CO2 paintball gun, you need to be aware that the pressure is much higher than when using a regular CO2 tank. This increase in pressure can cause the tank to rupture if it’s not properly maintained and inspected on a regular basis for wear and tear. Additionally, make sure you’re following proper safety precautions when handling your tanks – always use protective eyewear, don’t smoke near them, and never fill them above their recommended capacities. 
The Best Way to Use Compressed Air For Your Paintball Gun
First off, make sure that your gun is specifically designed for running on compressed air. Not all paintball guns can handle the pressure of compressed air, so you must check your model to make sure it is compatible.
If your gun is built for compressed air, then you should be able to use a tank that has an output of 2000-3000 PSI. If you have an adjustable regulator on the tank, you can adjust the output PSI based on what your gun requires.
It’s important to note that when using compressed air in a paintball gun, the velocity may be higher than with CO2 tanks due to the higher pressure and constant temperature of the compressed air. This could mean more powerful shots and greater accuracy for your paintball game! 
Background on CO2 and Compressed Air
Paintball guns use either CO2 or compressed air to propel paintballs out of the barrel. The first and most widely used gas is carbon dioxide, which is a gas that has been pressurized into liquid form and stored in tanks for use by paintball guns. Compressed air, usually referred to as high-pressure air (HPA), is an inert gas like nitrogen or oxygen but it must be kept at higher pressure than CO2 and requires special tanks called “compressed air systems”. 
There are many advantages to using CO2 in a paintball gun. First, it is familiar and easy for most players to use. Many recreational players have never used compressed air tanks, but they have all encountered the small 12-gram CO2 cartridges used in pellet guns and other toys.
CO2 also works well at higher temperatures than compressed air, which can be an issue during hot days on the paintball field. The gas is much more consistent within a wide temperature range as well, which makes it easier to regulate your shots during long games. 
In addition to being easy to find, CO2 cartridges are also much cheaper than compressed air tanks. Most CO2 cartridges for paintball guns cost less than five dollars each and can last multiple games. Compressed air tanks can cost anywhere from fifty dollars to more than one-hundred dollars depending on the size of the tank. If you plan on using your paintball gun often, these costs will quickly add up.
CO2 is usually available for purchase at most paintball fields or stores that cater to paintballers, making it quick and easy to get refills when necessary. 
If you’re just starting out, CO2 is a great choice because of the convenience factor. Compressed air tanks are larger and require more effort to transport and use. Most paintball fields have CO2 refills available, but compressed air refills usually require special equipment or trips to specialty stores.
CO2 cartridges are also much easier to store as they take up very little space and can be stored in any cool, dry place away from direct sunlight. Compressed air tanks need to be kept upright and in an environment that is free from dust and moisture.
Using CO2 in your paintball gun has many advantages over compressed air, including cost-effectiveness, ease of use, and convenience. 
Design of CO2 Tanks
CO2 tanks are designed differently than compressed air tanks. A CO2 tank has an internal regulator that regulates the pressure of the gas coming out of the tank, whereas a compressed air tank does not have this feature. This makes it easier to shoot from a CO2 tank because you don’t have to worry about keeping your shots consistent with different temperatures and pressures. 
Using CO2 as a propellant has its drawbacks. It can cause your paintballs to become brittle, resulting in broken shells that won’t fire properly and chunks of paint on the field. Additionally, it can be expensive because you need to continuously purchase tanks filled with CO2 gas that are usually sold separately from the gun itself. 
Compressed Air Advantages
The biggest advantage of using compressed air is that the pressure remains consistent no matter how much gas you use. With a CO2 gun, the amount of pressure changes depending on the temperature and altitude, so accuracy can be affected by changing weather conditions. Compressed air tanks are also less likely to experience inconsistent velocity due to variations in temperature or humidity. This makes them ideal for players who want increased accuracy from their paintball guns. 
Compressed air tanks also have more even gas flow, making them better for accuracy than CO2. This is because the gas is released in a more consistent rate and does not fluctuate as much with each shot. Compressed air guns provide players with improved accuracy and range due to their consistent pressure when compared to CO2 paintball guns. 
Compressed air tanks are also known to provide players with an increased range over CO2. This is because the gas flow is more consistent and the pressure does not drop off as quickly when shooting for long distances. Players who need more range from their paintball gun will find that compressed air gives them an edge in accuracy, distance, and consistency. 
Although compressed air tanks are more expensive upfront, they can save money in the long run. This is because CO2 tanks must be refilled regularly and may need to be replaced from time to time due to wear and tear. Compressed air tanks last longer and can usually be refilled for a lot less than buying a new tank of CO2. 
Compressed Air Disadvantages
Tanks Are Not Compact
Although compressed air tanks are still lightweight and portable, they come in bigger sizes than the CO2 tanks. This means that carrying around a tank of compressed air can be rather cumbersome as compared to the small and slim CO2 tanks. 
Compressed air tanks may cost more than CO2 tanks in the long run, but in the short term, they can cost a bit more. Since compressed air needs to be filled up regularly, this means that you will have to pay for refills on a regular basis. This makes it slightly expensive and time consuming as compared to using CO2 which is much cheaper and lasts longer. 
How Much Shooting Can You Do With Compressed Air vs. CO2
When it comes to shooting, compressed air is the superior choice. Compressed air provides a more consistent and reliable velocity than CO2, which can fluctuate due to temperature changes. This means that you will be able to shoot longer with compressed air than with CO2 before having to refill your tank. Additionally, compressed air tanks are typically larger and last longer, meaning fewer trips back and forth to the store or field for refills. 
How to Fill Your CO2 Tank with CO2
Now that you know if you can use compressed air in a CO2 paintball gun, let’s look at how to fill your tank with CO2. Here’s what you’ll need: CO2 tank adapter, CO2 tank or cylinder, and either a CGA320-to-Paintball adapter or an ASME certified filling station.
Then, attach the correct adapter to the CO2 tank. Next, connect the ASME certified filling station to the tank or use the CGA320-to-Paintball adapter for smaller tanks. Finally, open up the valve of your C02 tank and let it fill up until it reaches its maximum capacity.
When your tank is full, close the valve and disconnect all of the components. Make sure you keep track of how much CO2 you’re using when filling up your tanks, as this will help ensure that you stay within your budget.
