The way the regulator first stage reduces tank pressure is ingenious. A first stage consists of two air chambers separated by a valve. When the regulator is not pressurized this valve is open. When connected to a tank, air from the scuba tank flows into the first chamber, through the valve, and into the second chamber.
What is the difference between 1st stage and 2nd stage regulators?
Single-stage gas pressure regulators reduce cylinder pressure to delivery or outlet pressure in one step. Two-stage gas pressure regulators reduce cylinder pressure in two steps. … Conversely, the two-stage regulator shows a considerable droop, but only small supply pressure effects.

First-Stage Regulators are Underwriters Laboratories (UL) listed regulators designed for Two-Stage LPG systems. These First-Stage regulators reduce tank pressure to a lower pressure (usually 10 psig / 0.69 bar) for a Second-Stage regulator. Maximum allowable inlet pressure is 250 psig / 17.2 bar.
Can you breathe while scuba diving?
