How Much Oxygen in a Scuba Tank? The Technical Truth

You might be surprised. Standard scuba tanks don’t hold pure oxygen. Most use compressed air: about 21% oxygen, 78% nitrogen. Technical divers might use “Nitrox” (for example, 32% O₂) or even higher blends. Pure oxygen is usually only for certain specialty dives.

Tank Type	Oxygen Percentage	Typical Use
Standard Air	21%	Recreational Diving
Enriched Air (Nitrox)	32-36%	Extended Bottom Time
Pure Oxygen	100%	Deco, Medical

Want specifics? A standard 80-cubic-foot aluminum tank at 3,000 psi holds about 16.8 cubic feet of pure oxygen (if air filled). Always ask: How much oxygen in scuba tank for my type of dive? That’s your first step to a safe, thrilling experience.

How Much Does a Scuba Oxygen Tank Cost? Compare Your Options

Tanks come in many sizes. Costs can vary—by brand, build, and gas type.

Tank Size	Material	Price Range (USD)
63 cu ft	Aluminum	$160–$230
80 cu ft	Aluminum	$220–$350
100 cu ft	Steel	$350–$600

Refills? Expect $5 to $15 per fill when using standard air. Pure oxygen or mixed gas costs more. Quality tanks pay for themselves after just a few trips out. Curious how much does a scuba oxygen tank cost? Now you know!

FAQS on how much oxygen in a scuba tank

Q: How much oxygen is in a scuba tank?

A: Most standard scuba tanks contain compressed air, with about 21% oxygen, the same as regular air. Specialized tanks for technical diving may have higher oxygen percentages. Always check your tank label before use.

Q: How much oxygen in a scuba tank?

A: A typical scuba tank holds around 80 cubic feet (about 2,265 liters) of air, with roughly 21% being oxygen. That equals about 16.8 cubic feet (476 liters) of oxygen in a standard tank. This percentage can vary in special gas mixes.

Q: How much does a scuba oxygen tank cost?

A: The price of a new scuba oxygen tank ranges from $150 to $300, depending on size and material. Used tanks are often cheaper. Refilling the tank has a separate, smaller cost.

Q: Is a scuba tank filled with pure oxygen?

A: No, recreational scuba tanks are filled with compressed air, not pure oxygen. Breathing pure oxygen below 6 meters (20 feet) can be dangerous. Only special divers use higher oxygen blends with proper training.

Q: How long can the oxygen in a scuba tank last underwater?

A: The oxygen in a standard scuba tank typically lasts 30 to 60 minutes, depending on depth and breathing rate. Deeper dives and heavier breathing reduce this time. Always watch your gauge to stay safe.
