Scuba Tank Sizes And Pressures

Steel scuba tanks are denser than aluminum tanks meaning you have to be less concerned with buoyancy issues especially at the end of a dive.

Scuba tank sizes and pressures.

While steel and aluminium scuba tanks come in a wide range of sizes see above the following are the most commonly used sizes. 12 2 litre 100 cubic foot 232 bar steel cylinder rrp. Making a catalina aluminium scuba cylinder. For example most aluminum tanks from the smallest 6 cuft pony bottle to an 80 cuft tank have a fill pressure of 3000 psi.

The most common service pressures seen in modern scuba tanks are 2640 psi 3000 psi 3300 psi 3442 psi and 3500 psi. Smaller than an aluminum tank of the same capacity a steel scuba tank is a more compact air supply solution a fact that becomes doubly important for twin tank setups.

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.

The 2640 psi low pressure steel tanks are preferred by nitrox and technical divers who expect to be blending their gases using the partial pressure method. A drawback of high pressure scuba cylinders is that they require more metal to maintain the higher amount of compressed air inside. Most aluminum scuba tanks are rated for 3000 psi. High pressure cylinders are a new trend.
