Should I buy a CO2 or HPA tank?

Hi guys,

I´m back with another articles. This time it will be a little bit about my personal hobby, Paintball! Please, write me some comments if you like the content. Let’s dive right into it!

Many new players find themselves confused as to which pressure system to purchase for their first marker system or what to wear paintballing. The choice between CO2 (Carbon dioxide) HPA (High Pressure Air) tanks is very complicated and it depends on the type of player and their primary concerns. Below is a break down of the two pressure systems to make the choice a little easier:

Where CO2 tanks rarely cost over $35, HPA tanks could cost anything between $70 and $300. If the price of the paintball tank is an issue for you, you might want to consider getting a CO2 tank because it is relatively cheaper. It is important to note, however, that most facilities offer free refills for HPA tanks and charge anywhere from $3 to $7 for refilling CO2 tanks. Also, HPA tanks tend to have a longer lifespan than CO2 tanks.

Replacement Frequency:

Though the CO2 tank is cheaper, it has to be more frequently replaced. The cooling of the gas as it goes through your marker causes the rubber rings in it to shrink and to get hard. The same happens for HPA pressure systems but much less frequently. Keep in mind, though, that it is very cheap to replace the rubber rigs in the marker so the choice is down to whether or no frequent replacement will be an issue for you.

Quality of Game:

When you fire a CO2 tank fast and frequently, it will most likely cause a freeze-up. This is because the gas is drawn up into your marker as it is fired. The liquid CO2 in your tank cools as your marker is fired. With frequent and high-speed firing, the tank gets too cool and the CO2 does not have enough time to convert into gas for the shot. This will most frequently result in a poor shot or no shot at all. HPA tanks do not cause freeze-ups and can be fired as often as one pleases. This means that you have to play strategically using a CO2 tank because you know you have a limited number of shots at a time. With an HPA tank, you can shoot as and when you please.

Note that most modern guns only use the HPA pressure system. You might want to factor that in while choosing the tank that best suits you. Despite this, remember that there is no difference in accuracy in HPA and CO2 so no matter which system you choose, your game will not be affected. It all boils down to which system fits your budget, what you can handle in terms of the maintenance of you tank and the quality of game that you hope for.
