Compressed Air and CO2 Tank Refills

Welcome to the

Compressed Air and CO2 Tank Refills

We fill Compressed Air and CO2 Tanks at our Denver indoor field!


Before filling each tank, our professional staff checks to make sure that the bottle is still within its hydrotest date and that there are no physical safety concerns. This is to ensure safety and that we give you the best quality product possible. A hydrotest date is usually stamped or wrapped into the tank. This date states when the tank was made and if it needs to be retested to make sure it is structurally sound. Continue reading to learn how to get your tank hydro tested.

If your tank is out of date, we are happy to help you get it recertified. Getting your tanks hydrotested is made easy at American Paintball Coliseum. Simply bring your tank to our paintball store in Denver and our friendly staff will gather your tank and a bit of information to contact you when it is finished.

Hydro testing usually takes anywhere from 7-10 days to complete and return. Upon picking up your tank, we will make sure the tank is in good working order for use. Hydro testing a tank will cost $30 at the time of picking up your compressed air tank.
