Standard Scuba Tanks High-Capacity Gas Cylinders for Safe Diving

Q: What are the most common standard scuba tank sizes?

A: The most common standard scuba tank sizes are aluminum 80 cubic feet (11.1L) and steel 12L (around 85 cu ft), with a working pressure of 3,000 psi (207 bar) for recreational diving.

Q: What is the capacity of a standard scuba tank?

A: A standard scuba tank typically holds 80 cubic feet of air at 3,000 psi, though capacities vary between 50-130 cu ft depending on material (aluminum/steel) and pressure ratings.

Q: What are the dimensions of a standard gas cylinder for diving?

A: Standard aluminum scuba tanks are approximately 7.25 inches (18.4 cm) in diameter and 25-26 inches (63-66 cm) tall, while steel tanks may be slightly shorter and narrower.

Q: Are standard scuba tank sizes universal worldwide?

A: While 80 cu ft tanks are widely used, standards vary: North America favors 3,000 psi cylinders, while Europe often uses 232-300 bar (3,360-4,350 psi) tanks with metric volume measurements.

Q: How long does a standard scuba tank last during a dive?

A: An 80 cu ft tank lasts about 45-60 minutes for recreational diving at moderate depths (10-20m), depending on breathing rate, depth, and exertion level.
