FAQS on standard scuba tank

Q: What are the common standard scuba tank sizes?

A: The most common standard scuba tank is the aluminum AL80, holding 80 cubic feet of air at 3,000 psi. Other sizes include smaller cylinders like AL63 (63 cu ft) and larger steel tanks like LP120 (120 cu ft). Sizes vary based on material and regional standards.

Q: What is the standard gas cylinder pressure for scuba tanks?

A: Most standard scuba tanks operate at 3,000 psi (200 bar) for recreational diving. High-pressure cylinders may reach 3,500-4,500 psi (230-300 bar), but these are less common. Always check manufacturer specifications for safety.

Q: Are standard scuba tank dimensions universal globally?

A: No, standard scuba tank sizes differ slightly by region. For example, European tanks often use metric measurements (e.g., 12-liter capacity), while U.S. tanks use cubic feet. Always verify local standards before purchasing or refilling.

Q: How long does a standard scuba tank last underwater?

A: An AL80 tank lasts roughly 60 minutes for a diver at 10 meters (33 feet) with moderate exertion. Duration depends on depth, breathing rate, and tank size. Deeper dives reduce air supply significantly faster.

Q: What materials are used in standard scuba tanks?

A: Most standard scuba tanks are aluminum (lightweight, corrosion-resistant) or steel (durable, higher pressure capacity). Aluminum tanks like the AL80 are popular for recreational diving, while steel suits technical divers needing extended air supply.
