Scuba tank sizes chart.

Scuba cylinder specifications for buoyancy and weighting calculations. If you are already using steel. When scuba divers calculate their buoyancy with an aluminum cylinder it is essential for them to know the relative buoyancy characteristics of their chosen cylinder at full pressure capacity and also at their minimum reserve 500psi. There is a lot of information listed on the crown of the tank and the order in which the information is listed varies from tank to tank but the codes are standardized and easy to read if you know what to look for.

Tank diameters are a more significant consideration. Standard psi in an aluminum scuba cylinder is 3000. Divers direct also carries the 40 cu ft 50 cu ft 63 cu ft and 100 cu ft. A scuba tank s capacity is determined by its size and pressure rating.

There are many sizes of scuba tanks but you will find common standards throughout the industry. Most tanks have capacities ranging from 50 to 120 cf with various compressed air pressures. The information is believed to be accurate but is not guaranteed. Compiled by huron scuba snorkel adventure travel inc.

The size and working pressure of your scuba tank can be determined by looking at the markings on the crown of your tank. Standard aluminum tanks typically have a capacity of 80 cf with a. 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. If you have better information or corrections please email it to us for.

Most primary tanks aluminum or steel are the common diameter of 7 inches. 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. To give you the lightest and hence an optimum wall thickness steel tanks cylinders with an ideal buoyancy our scuba diving cylinders are diligently manufactured using high quality steel plates. 80 cubic foot tanks are the most popular among recreational divers and are also the most commonly found tanks on the water.

Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a. The information below was compiled from a variety of sources including luxfer pressed steel tank catalina and oms.
