Your question: How does a scuba first stage work?

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.
