AquaLung Regulators
Regulators Information
Scuba regulators are designed to reduce the high-pressure air from the scuba cylinder to a level where the diver can breathe comfortably and safely. Jacques Cousteau and Emile Gagnan developed the original regulator, the aqua lung. It was a twin-hose system that reduced the pressure in a single stage connected to a cylinder. These days, regulators are a single-hose design and the pressure is reduced in two stages. The first stage reduces pressure from the cylinder down to near 10 bar, then the second stage delivers air on demand. (That’s why the second stage is sometimes called the demand valve.) Your regulator is the most important component of your diving equipment. It delivers the air you need to breathe. It is your life-support system. By reading through the selection criteria here and matching the features you require in the following pages you will be able to make an informed decision.
