Diving gas

Scuba-grade Oxygen and Helium cylinders

Breathing air for deep diving Trimix: A mixture of oxygen, nitrogen and helium. Often used in deep diving in technical and commercial diving instead of air to reduce nitrogen toxicity and to avoid the risk of oxygen poisoning.Breathable gas for deep diving Heliox:  It is a mixture of oxygen and helium. And often used in very deep diving to eliminate nitrogen poisoning.Breathable gas for deep diving Heliair:  A form of trimix  is a mixture of helium and air without mixing with pure oxygen. It always has a ratio of 21 oxygen and 79 nitrogen. The balance of the mixture is helium.Hydreliox:  A mixture of oxygen, helium, and hydrogen. And used for diving below 130 meters.Hydrox:  A mixture of hydrogen and oxygen gas, used as a breathing gas for very deep diving.
