Air Receiver Capacities
If your tank is not listed in the table to the left, use the following
formula to calculate the tank size (gallons) and then estimate
the cubic feet tank capacity at a given pressure from the table
above.
Height and Radius are in inches
Tank Gallons = Tank Height x (Tank Radius)
