Dräger model BG 160 A
The successor to model BG 130
The Dräger device model 160 was designed by Dräger in 1933. The device was launched on the market in 1934. BG stands for Bergbau – Gerät. The breathing apparatus features a lever that activates a metering valve at a certain point during inhalation. This valve admits fresh oxygen. In addition to breath-controlled dossing, the device also offers a constant gas supply of 1.5 ltr/min. However, if oxygen consumption increases due to increased labour, the siphon can make up the shortfall by increasing the dosage to 2.1 ltr/min. In addition to the constant supply and breath-controlled dossing, a manual bypass is also available that realises an even greater flow. The device is equipped with disposable cartridges and features a 150-bar 2-litre oxygen cylinder. The device based on the 1924 design was equipped with a side connection or a over the shoulder configuration of the breathing hoses.
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!
