Tank Fill Calculator

Please complete all of the fields and then press the "Calculate Fills" button to determine how many fills you can get with your airgun. Then press the "Compare" button to compare the number of fills with a standard 80 cu. ft. scuba tank with a 3000 psi working pressure to see the advantage of the carbon fiber tank.

As you will see, the carbon fiber tanks give substancially more fills than the standard scuba tanks, which reduces the frequency you will have to have your air supply refilled. This savings alone will more than pay off the price of the carbon fiber tank under normal use within the lifetime of the tank.
