How long is the air in a scuba tank good for?

Diving with pure oxygen can kill a diver even at shallow depths. 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 will a scuba cylinder last at 20 meters?

Simply put, if a cylinder lasts 60 minutes on the surface, it will only last 20 minutes at 20 meters/66 feet/3 bar. And in reality, it may last even less time, because at depth you may be a little more excited and breathing a little faster!

How long does a 12 liter scuba tank last?

An average male’s lung is about 6 Liters. So if we fill our standard 12-Liter tank with atmospheric pressure of 1 bar, that’s two breaths on the surface. 200 bar, however, is 200 x 12L = 2400L, so about 1200 breaths on the surface. Remember depth will use more as we established above.
