Catalogue Scuba Diving: Hardware: RegulatorsRegulatorsYour regulator is the most important component of your diving equipment. It delivers the air your need to breathe. It is your life support system.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 10bar, then the SECOND STAGE delivers air on demand. (That's why the second stage is sometimes called the demand valve.)
