Dräger Sauerstoff Klein Gasschützgerät Modell KG210
KG stands for ‘Klein Gasschutzgerät’ and was developed between WW1 and WW2. The model KG2100 was the successor to model KG1928 and was produced in large numbers. It was designed for civil defence and fire brigades and for mining companies. The unit was very popular. Also the KG 130 and 160 are build by Dräger. 210 might be chosen for 3,5 hour user time (?)
The model had one outward-hinged doors. The breathing system that provided the gas injection was the further development of lung-controlled breathing. Each time the wearer breathes, a fork connected to the lung injects gas into the lung.
The unit has been in use up to the 80’s
The unit was worn with a face covering mask and had a full circuit with separate in and out breathing hoses. The wearing time of one hours resulted in the presence of water vapor and saliva due to intensive breathing and the Co2 removal process. For this purpose, a moisture trap was mounted in the sidemounted breathing hoses. Masks could also be equipped with communication systems in later years.
The popular device was produced in thousands .
The lung dosage unit was mounted on the outside of the lung in a horizontal position.

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!
