Aluminum Tanks - The aluminum tanks cost
significantly less then a steel tank. Aluminum tanks are more buoyant
than steel tanks, so you may be finding yourself adding a few extra pounds
on your weight belt.
The difference between Pressure & Volume - It should be noted that the
pressure of a tank is not a measure of the size or volume
of a tank. For example, most aluminum tanks, from the smallest 6 cuft pony bottle to an 80
cuft tank, have a fill pressure of 3000 psi. For a 6 cuft bottle, this means at 3000 psi
the tank contains 6 cuft of air. For an 80 cuft bottle this means at 3000 psi the tank
contains 80 cuft of air. Tanks come in a variety of combinations of volumes and fill
pressures but the cubic foot (cuft) volume is the measure of how
much air a tank holds.
