All of the different units of measure used for carbon fiber tank sizes and fill capacities can be confusing. This comparison chart lists the commonly used carbon fiber tanks. The first two columns show interior volume of each tank size in liters and cubic inches. The third column is the air capacity for each tank size filled to 4500 psi. A few airgun dealers advertise that their tanks hold more air than competitor brands even though the internal capacity is identical. The two most common sized tanks sold are the 6.8 liter which actually holds 66 cubic feet of air at 4500 psi and the 9 liter tank that holds 88 cubic feet at 4500 psi. Their 6.8 liter and 9 liter tanks are sold to fire departments as 45 minute and 60 minute breathing air tanks.
The small 90 cubic inch tank is commonly sold for paintball but is also sold for PCPs. The 110 cubic inch tank is the most popular compact tank size. The 2 and 3 liter tank sizes are sold on Aliexpress and Ebay. The 4.5 liter size 30 minute tank is included for comparison but only available from Ebay or vendors which sell used fireman's tanks. The two most popular carbon fiber tanks sold by airgun dealers are the 414 cubic inch, 6.8 liter 45 minute fireman's tank, or the large 550 cubic inch, 9 liter 60 minute fireman's tank. The only sources of 12 liter tanks is from Aliexpress or some European dealers.
The chart below compares them by size and air capacity in ascending order of internal volume and air capacity at 4500 psi. This chart will help to compare the sizes and units of measure used on all of the popular carbon fiber tanks.
