An Average Diver, at an Average Depth, With an Average Tank
Based on personal experience, an average open-water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 to 60 minutes before surfacing with a safe reserve of air still in the tank.
What is air tank in scuba diving?
A scuba tank is a gas cylinder used to store and move high pressure breathing gas needed by a diver. These cylindrical pressure vessels when combined with a valve are available in a whole range of pressures, dimensions, and capacities.
How much does it cost to fill a scuba tank with air?
It is very inexpensive to fill an air tank at a scuba store or air supply provider. If you head to your local dive shop or scuba retailer, it should cost you around $5 to fill a scuba tank.
Is a scuba tank just compressed air?
Recreational scuba tanks are filled with compressed, purified air. This air contains about 20.9% oxygen. Several risks are associated with the use of pure oxygen in diving.
How long can you scuba dive on a tank of air? – Related Questions
Do Scuba divers use 100% oxygen?
On the deepest working dives, at depths greater than 600 m, ambient pressure is greater than 6100 kPa and the divers breathe gas mixtures containing about 2% oxygen to avoid acute oxygen toxicity.
Why is 100% oxygen not used for scuba divers?
Scuba diving beyond 20 feet with pure oxygen can be hazardous and can lead to lung damage and the condition known as oxygen toxicity, which actually decreases the amount of oxygen transported into the blood.
Is an oxygen tank compressed gas?
Pure oxygen in a portable tank comes in 2 different states: compressed oxygen gas and liquid oxygen.
Is oxygen just compressed air?
Air and oxygen are often used interchangeably but both are different terms. Oxygen is a pure element while air consists of combination of several elements. Air comprises of the mixture of several gases present in the atmosphere and oxygen is termed as one of the essential components present in the air.
Can you breathe compressed air underwater?
“As long as there is air in the tank, they will be able to breathe,” he said. A real concern, though, is divers coming up too fast and harming the lungs. Gas is more compressed the deeper you go, so it takes more air to inflate the lungs.
Can compressed air be used for breathing?
Compressed air gets used across a range of industries to provide respiratory protection. It’s used in applications where the risk of breathing ambient air is too high to mitigate using half or full-face respirators. But it is not safe to breathe the compressed air directly following compression.
What two things should you never do with compressed air?

What should you never use compressed air for?
Under no circumstances should anyone use compressed air to clean off clothing or any part of the body. Although many people know using compressed air to clean debris or clothes can be hazardous, it is still used because of old habits and the easy availability of compressed air in many workplaces.
What can compressed air under 30 psi be used for?
The phrase “reduce to less than 30 psi” means that the downstream pressure of the air at the nozzle (nozzle pressure) or opening of a gun, pipe, cleaning lance, etc., used for cleaning purposes will remain at a pressure level below 30 psi for all static conditions.
Can compressed air penetrate the skin?
When high-pressure compressed air is used to clean skin and clothing, it can penetrate the skin and enter the bloodstream. This, in turn, can cause blood vessels to become blocked by air bubbles, triggering stroke-like symptoms. If left untreated, an air embolism can lead to coma, paralysis and death.
Can I use hose pipe for compressed air?
Avoid rubber hoses for compressed air piping.
Can I use copper pipe for compressed air?
Copper piping is an excellent choice for use with air compressors. Any condensation that builds up in the system will not corrode copper air compressor lines, so the risk of debris entering the system is very low. It also withstands heat well.
Is it OK to use PEX for air compressor lines?
A: No, PEX pipe is not intended for compressed air applications.
How much psi can PVC handle?
Many PVC pipes are rated for 300-600 PSI.
Is PVC OK for compressed air?
OLYMPIA — The Department of Labor and Industries warned today that plastic polyvinyl chloride (PVC) pipe cannot be used in compressed air piping systems without the risk of explosion.
Can you use SharkBite fittings for compressed air?
SharkBite, part of RWC’s family of brands, now offers a new range of brass push-fit fittings and anodised aluminium pipe to simplify small to large commercial and industrial compressed air installations.
