between 3 and 18 litres
Beside above, how do I choose a scuba tank? A scuba tank's capacity is determined by its size and pressure rating. Most tanks have capacities ranging from 50 to 120 cf, with various compressed air pressures: low-pressure (LP) with 2400-2650 psi, standard pressure with 3000 psi, and high-pressure (HP) at 3300-3500 psi.
Also know, what is the best size scuba tank?
Most recreational divers find a common aluminum 80 to 100-cubic-foot tank is sufficient for their needs. An aluminum 63 cft may be a better fit for a younger and shorter diver while still providing enough gas for their needs. Larger divers tend to have greater gas consumption rates in direct proportion to their size.
