  2. Rebreather diving - Wikipedia

    en.wikipedia.org/wiki/Rebreather_diving

    In rebreather diving, the typical effective endurance of the scrubber will be half an hour to several hours of breathing, depending on the type and size of the scrubber, the absorbent characteristics, the ambient temperature and pressure, the operational mechanics of the rebreather, and the amount of carbon dioxide produced by the diver, which ...

  3. Rebreather - Wikipedia

    en.wikipedia.org/wiki/Rebreather

    A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user.

  4. Underwater breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Underwater_breathing_apparatus

    Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...

    Dave Shaw died in 2005 in an attempt at the deepest ever body recovery and deepest ever dive on a rebreather at 270 m (886 ft). [82] [83] Brigitte Lenoir, planning to attempt the deepest dive ever made by a woman with a rebreather to 230 m (750 ft), died on 14 May 2010 in Dahab while ascending from a training dive at 147 m (482 ft).

    A Diving rebreather is an underwater breathing apparatus that absorbs the carbon dioxide of a diver's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the diver.

  8. Halcyon PVR-BASC - Wikipedia

    en.wikipedia.org/wiki/Halcyon_PVR-BASC

    The only restrictions on size are what the diver can carry, and the scrubber endurance. The cylinders are normally rigged with open circuit regulators in the standard DIR configuration for bailout, and a supply hose with quick connector on each for the rebreather supply.

  9. Halcyon RB80 - Wikipedia

    en.wikipedia.org/wiki/Halcyon_RB80

    The Halcyon RB80 is a non-depth-compensated passive addition semi-closed circuit rebreather of similar external dimensions to a standard AL80 scuba cylinder (11-litre, 207-bar aluminium cylinder, 185 mm diameter and about 660 mm long). It was originally developed by Reinhard Buchaly (RB) in 1996 for the cave exploration dives conducted by the ...
