Tank Size Guide
Below is a table to aid in sizing a tank. In general, for a given capacity, it is more economical to select a smaller diameter tank with a longer shell, than a larger diameter and shorter shell. However, physical limitations such as available floor space, ceiling height, and door width sometimes dictate the size of a tank. Any intermediate sizes may be specified if desired, and larger and longer tanks may also be specified. Please consult factory for price and availability.
