Offering unparalleled levels of mission flexibility, Shadow has established itself as the industry leading underwater life support system for operational capability and performance.

Latest developments include a systems approach to integrating life support and combat equipment. This includes a rapid clip-on / clip-off interface with ballistic protection vest, use of nitrox for diving below the safe depth of oxygen and a back mount option optimised for use with manned free flooding submersible vehicles.

The back mount kit enables the standard front mount Shadow to be back worn providing ready access to mission equipment and is suitable for a range of mission profiles that include:

• Over the beach operations

• Diver propulsion vehicles

• Swimmer delivery vehicles

 

FEATURES

The reconfiguration to back mount is readily undertaken by the user in the field in a matter of minutes without the use of tools. The back mount variant may be worn as a stand-alone rebreather or interfaced with a ballistic protection vest.

PRINCIPLE OF OPERATION

When configured for oxygen use, via a first stage pressure reducer, oxygen is supplied from the pressure vessel (cylinder) to a demand valve that automatically adds oxygen to the re-circulation sub-system.

One-way check valves in the breathing hose mouthpiece assembly ensures exhaled breathing gas is re-circulated through a long endurance scrubber canister that removes exhaled CO2 prior to re-inhalation. A readily accessible submersible pressure gauge enables continual monitoring of oxygen pressure vessel.

When configured with the nitrox kit, Shadow may be used in either oxygen or nitrox mode. To access the nitrox gas
supply stored in a separate pressure vessel (cylinder), the diver rotates a multi-turn gas switch-over valve that enables a constant mass flow of nitrox gas (60% oxygen / 40% nitrogen) into the re-circulation sub-system at 6 litres per minute. Following a gas switch from oxygen to nitrox, the diver may descend to a recommended maximum depth of 24msw.
