Database Japanese Oxygen Rebreathers

This database shows the oxygen rebreathers developed and used in Japan. The breathing apparatus are used for different purposes. The first models were mainly used in the mining industry and during the First World War devices were developed to escape from submarines. Later the oxygen breathing apparatus was used by the military but also by sports divers who practise photography or want to dive with light systems. Oxygen devices, because of their characteristics, can offer a long operating time, both above and under water. An important warning for homebuilders; Oxygen rebreathers require specific knowledge and are repeatedly involved in fatal accidents. Never dive alone, make sure nitrogen is removed from the loop and do not dive deeper than 6 metres. No rights can be derived from the information on these pages.
