Content: The purpose of a scuba diving regulator is to reduce the high pressure air in a scuba tank to a breatheable pressure on demand. Scuba regulators are simple devices, and the method in which they reduce high-pressure tank air to a breathable pressure is easy to understand. Even the simplest scuba regulators do this adequately, at all recreational diving depths and with remarkable reliability. Regulator Terminology
