Paintball CO2 tanks have developed a lot in only the last couple of years. 10 years ago, you would have to buy air tanks costing $200 or more; they were also mounted right to the base of the paintball gun.

Because of the need to change paintball air tanks both prior to a game and afterward (or fix any damaged tanks quickly), new manufacturers have consistently worked on making tanks better so that more options are available.

Compressed air and CO2 are both pressure sources for markers that are used to launch the paintball out of the barrel. The choice between these is entirely dependent on the marker that you are using.

CO2 is considered the more affordable choice and is much easier, however, it's all down to what your marker requires and what you are willing to spend.

What are Paintball CO2 Tanks?

The biggest question you can probably ask apart from ‘what paintball gun is best to buy’, would be ‘what's the difference between using a CO2 and compressed air tank to power a paintball marker?’

Both are viable pressure sources and will eject a paintball out of the barrel, but this is where any similarities end. Depending on your marker, sometimes you can only use one or the other without damaging your marker.

Carbon dioxide tanks maintain the gas in CO2 liquid form. These come in a variety of sizes like 4oz, 12oz, and 20oz (Oz). These tanks are built to maintain weight as ounces rather than volume.

This can be confusing but what really matters is how heavy the liquid is. Your tank can only be filled according to its specific rating. CO2 aren’t found as often on a paintball site, in addition, it costs more to fill, with a typical spend of around $10.

How Paintball CO2 Tanks Work

The first paintball guns like the Nelspot 007, PGP and NSG Splatmasters utilized liquid CO2 and thus set the benchmark for several years.

As it turns from a liquid state to a gas it expands and creates pressure; this is what fires the paintball. This pressure fluctuates because of altitude, temperature, and other factors. Paintball uses two different types of vessels: disposable CO2 cartridges or reusable CO2 tanks also called CO2 bottles.

A lot of disposables are 12-gram CO2 cartridges commonly found on stock markers and certain paintball handguns such as the Tiberius T8.1. The refillable CO2 tanks are constructed from aluminum vessels using a valve and are full to the brim.

There are certain benefits to CO2 bottles. The main reason for CO2 was popular for so long was its price. Paintball CO2 tanks are inexpensive and allow players to purchase several in order to last the whole day of shooting.

Filling up is fairly low-cost, and if there isn’t a professional paintball store where you live then you can visit a welding and flame extinguisher supply store to have them filled.

CO2 tanks are streamlined and yield a good deal of shots due to their size and weight compared to compressed air.

The fact remains that compressed air tanks have to be shipped when empty due to regulations by the Department of Transportation. With these kinds of tank, you have to have them filled somewhere locally.

The only exception to this rule is the 12-gram cartridges or the one-time use disposable CO2 cylinders, although they can be sent by ground service only.

A hydro date is the month and year that the tank has been formally safety tested. Typically the hydro date is good for 5 years (some market fiber wrapped tanks are 3 decades, as indicated on the label).

The tank has to be retested five years following the month on the tank.

  • CO2 tanks are filled through the valve and must be completely emptied before filling to get a suitable fill.

One handy feature of this is that you don't have to take the tank off the mark to fill it and you can top off between games rather than having to empty and completely refill like CO2.

  • Shop air compressors and tire pumps cannot fill a compressed air tank. However, one common means of filling tanks would be to use a scuba tank equipped with a Scuba Fill Station.
  • Compressed Air tanks can be found in 3000 and 4500 psi pressure ratings. 4500 psi tanks manage more pressure and therefore supply many more shots.

Shot counts change between markers, but the majority of spool valve markers get about ten shots per cubic inch in 3000psi and 15 shots per ci in 4500psi. More efficient designs like Spyders and Egos can give far more shots.
