LAR V Draeger Close Circuit Underwater Breathing Apparatus (UBA)

The LAR V Draeger is a self-contained closed-circuit, 100 percent oxygen, underwater breathing apparatus, designed for clandestine operations in shallow water.?The LAR V is worn on the diver's chest.?With this closed-circuit system, the diver breathes 100 percent oxygen and his exhaled breath is re-circulated in the diving apparatus.?The divers exhaled breath passes through a chemical filter which removes carbon dioxide, replenishing the oxygen that is consumed.?Depth, water temperature and oxygen consumption rate all affect the duration of the LAR V Draeger.
