Exhaust gas returns to the bell through the diver's umbilical exhaust hose, where it passes through a water separator and trap then through a back-pressure regulator which controls the pressure in the exhaust hose and which can be monitored on a pressure gauge in the bell and adjusted by the bellman to suit the excursion depth of the diver.
The Aqua-Lung is a self-contained open-circuit demand system, which means that breathing gas is provided from high-pressure storage carried by to the diver on demand, when the diver inhales and reduces the pressure in the supply hose, subsequently the flow is shut off when not required. Once breathed, the exhaled gas is vented to the surroundings.
A high pressure diving compressor has a delivery pressure which is usually over 150 bar, and is commonly between 200 and 300 bar. The pressure is limited by an overpressure valve which may be adjustable. Most high pressure diving air compressors are oil-lubricated multi-stage piston compressors with inter-stage cooling and condensation traps ...
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
The systems used to supply air through the hose to a demand valve mouthpiece, are either 12-volt electrical air pumps, gasoline engine powered low-pressure compressors, or floating scuba cylinders with high pressure regulators. These hookah diving systems usually limit the hose length to allow less than 7 metres depth.
A burst low pressure hose will usually lose gas faster than a burst high pressure hose, as HP hoses usually have a flow restriction orifice in the fitting that screws into the port, [4]: 185 as the submersible pressure gauge does not need high flow, and a slower pressure increase in the gauge hose is less likely to overload the gauge, while the ...
