Bergbau-gerät 1923 with breathing operated oxygen addition
Inflation and economic crisis force the Dräger Company to close its plant and lay off all its workers. After the end of the war(1914-1918), the market for Dräger products shrinks; the Company is forced to turn to the manufacture of alternative products such as linen, clothing, and curtains. In the meantime, numerous competitors copy the products developed in Lübeck. Bernhard Dräger counters the loss of international patents, which hit the Company hard, with strong product innovation. This strategy helps the Company regain a foothold in its old markets in the early twenties. Closure in 1923 is another setback, but sales stabilize in 1924. But it will be 1928 before the Company recovers sufficiently to achieve a headcount of 300.
Despite this difficult period, the company manages to introduce the Bergbau-gerät Modell 1923. The unit is a further development of the early breath controlled apparatus with overpressure. This model also has a dosage unit built into the breathing lung that regulates the oxygen dose.
Any additional information of this unit is welcome!
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!
