In 1903 ‘Sauerstoff-Fabrik Berlin Gmbh’, developped a new breathing apparatus with a regulator.
The regulator made it possible to set a certain flowrate so depending on labour the oxygen addition could be set.
The unit could be equipped with a helmet and also a telphone system
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
