The Draeger Norge II (article no Draegerwerk T5650) is
an Oxygen Closed Circuit rebreather.
The Lt Lund II is the successor of the Lt Lund I and
the model 138, the latter was the classical Baracuda tauchgeräte that Hans
Hass used in the 1940's. According to G. Haux "Tauchtechnik" the Lt Lund was
developed 1953 - 54 in collaboration with the Norweigan Navy and Leutnant
Lund.
The main improvements made to the Norge (as compared
to the Lund II) were:
·
Larger (3.8 L) sorb canister
·
Larger diameter breathing hoses
·
Larger diameter non-return valves placed in
the DSV
·
The pressure gauge is mounted directly on
the manometer
The Norge
unit comes in an early version , the Norge I, with a canvas breathing bag
and a later, Norge II, (shown below) with a fabric reinforced rubber
breathing bag.
