You cannot breathe directly out of a scuba tank because of the high pressure. A regulator reduces pressure to safe a level that can be inhaled by the diver. A diving regulator has two parts: the First Stage reduces the tank pressure and connects it to the Second Stage which contains the mouthpiece for breathing
The low pressure ports are located on arotating turretthat ensures that regulator and instrument connections are always in the right position. The rotating turret swivels on 360° axis and features five low-pressure ports designed to allow the use of more connections without interfering between them.The air passages are enlargedto allow for peaks performance of 2,700 liters/minute (95 cu ft/minute). The conical filter has a large surface area and allows 200% more air flow than standard models. It’s easy to change from DIN to INT, both 200 and 300 bar. Itstechnologically advanced designdelivers consistent intermediate pressure andhigh performanceeven with low tank pressures.
