3 Types of Scuba Diving Gas Mixes - AquViews - Leisure Pro

Scuba Tank Air Composition. Nitrox. Regular air is over three-quarters nitrogen, less than one-quarter oxygen, and trace amounts of other gases. Nitrox typically increases the amount of oxygen to between 22% and 40% of the total gas volume, but divers usually use between 32% and 36% (also known as EAN32 and EAN36). This scuba diving gas mixture ...

How Air Scuba System Recycles Air Under Water - The Tech ...

Apr 09, 2012·Scuba divers who use the conventional scuba systems must be very careful to monitor the depth and time while they stay underwater. They have to endure a series of lengthy decompression steps during resurfacing. But the thing is, the oxygen tank that scuba divers take with them under water is filled with limited oxygen. Before the oxygen finishes, the divers have to come up.
