Aqua Lung
The aqua lung was invented by Jacques Cousteau and Emile Gagnan in the years 1942-1943. The aqua lung was was the first trademark device self-contained underwater breathing equipment. The parts included are air cylinders, the regulator and the harness.
It was made for the use of underwater explorers. They wanted to find a way to breathe underwater, so it would be easier to explore and discover new things. The device was a simple invention. Here is how it worked:
~The cylinders are manufactured from steel or aluminum alloy and they are found in multiple capacities. The diver's air is applied through the cylinders located on the back of the diver. Air present in the cylinder at a high pressure can be decreased before the diver breathes it in. For this intention, a regulator is attached to the cylinder to fix and change the air pressure levels to the same pressure as the water around them. The regulator we use is the single hose regulator. It contains a cylinder valve attached to the hose and it is held at the divers mouth. The harness is then used for carrying it on the divers back.
The aqua lung used open circuit technology to retrieve clean air and dispose of used air as opposed to Closed circuit technology that recycles the used air to make it breathable again.
