The air is then led through the intermediate pressure hoses to the breathing...

WORKING PRINCIPLE • The pressure regulator is a pressure-balanced, piston-equipped counter-flow regulator. The result of balancing is firmly reduced pressure (intermediate pressure) that is not affected by pressure fluctuations in the air supply (high-pressure). The regulator opens at corresponding gas pressure. The principle is called downstream regulation. Thanks to this, the regulator can regulate pressure from the maximum flow rate to a minimum supply pressure of approximately 15 bar (218 psi). The regulator reduces the highest pressure to 8.5 bar (123 psi) dynamic pressure. The...

REDUNDANT BREATHING SYSTEM • The regulator unit comprises two pressure regulators. The primary regulator provides the primary breathing valve or the full-face mask valve with intermediate pressure air, and the secondary regulator provides the octopus breathing valve with intermediate pressure air. The primary regulator receives air via the reserve valve handle, while the secondary regulator is always directly supplied with air from the air cylinders. Thus the system has a backup system. The diver can always obtain respiratory air in three different ways: · f the surface air supply from the...

PRESSURE GAUGE • Pressure in the cylinder pack can be read from the pressure gauge. The pressure gauge is connected to the regulator's connecting pipe via a high-pressure hose. The air pressure affects a Bourdon tube (a pipeshaped spring) in the pressure gauge, which in turn affects the indicator. The safety valve (behind the rubber covering) on the rear of the pressure gauge opens if the pressure in the pressure gauge casing rises too much. The rubber covering protects the pressure gauge from impact damage and dirt. BREATHING VALVE • The Divator breathing valve is available in three...
