> > Aluminum Scuba Tanks


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.

All diving cylinders we offer are DOT (Department of Transportation) and TC (Transport Canada) approved
