What kind of air do scuba divers use?

What type of air do scuba divers use?

Nitrogen. Nitrogen (N2) is a diatomic gas and the main component of air, the cheapest and most common breathing gas used for diving. It causes nitrogen narcosis in the diver, so its use is limited to shallower dives. Nitrogen can cause decompression sickness.

Do scuba divers use compressed air?

Compressed air for scuba diving

To breath under water, scuba divers carry a air-tank with them filled with compressed air. For recreational diving this is normally normal atmospheric air, but compressed about 200 times to 200 bar (or 3000 psi).

Is scuba diving bad for your lungs?

Can I be seriously hurt while scuba diving? Yes. The most dangerous medical problems are barotrauma to the lungs and decompression sickness, also called “the bends.” Barotrauma occurs when you are rising to the surface of the water (ascent) and gas inside the lungs expands, hurting surrounding body tissues.

Why do scuba divers breathe compressed air?

Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. … And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs.

Is scuba air filtered?

As a diver’s life quite literally depends on the quality of breathable air in the scuba tank, air filtration is an integral component of scuba air compressors and ensure clean odorless and moisture free air.

Can an air compressor fill a scuba tank?

Scuba tanks typically need to be filled at very high pressure (about 3,000 psi). Using a regular air compressor would only be able to provide a fraction of the air that scuba compressors can. Secondly, the scuba compressors have filters that are designed to purify the air that goes through them and fills the tank.
