• The air from the cylinder pack is fed to the pressure regulators that reduce the high pressure to an
intermediate pressure. The air is then led through the intermediate pressure hoses to the breathing valves.
The regulator unit comprises two pressure regulators in a connecting pipe with a reserve valve. The primary
pressure regulator has two hoses connected. One of them feeds the primary breathing hose with its primary
breathing valve regardless of whether it is connected to a full-face mask or a mouthpiece. There is a quick
coupling on the hose that interacts with the external surface air supply. The other hose is intended for
inating dry-suits (Optional).
The secondary pressure regulator has two hoses connected. One of them feeds the secondary breathing hose
(the octopus hose) with its octopus breathing valve. The other hose is intended for Divator BCW, buoyancy
compensating vest (Optional).
The regulator unit is connected to the cylinder valve with a coupling that is tightened by hand. The regulator
unit cannot be loosened without the air rst being ventilated from the system. The pressure regulator is a
piston-type with extremely high air ow capacity. To make the regulator small and light, the piston has been
balanced, which also guarantees stable and even intermediate pressure. The pressure in the air cylinders can
be controlled on the pressure gauge, which is connected to the regulator with a high-pressure hose.
