Manual operated and constant mass flow Biomarine Rebreathers
The Biopak 60 and 240 rebreathers are not made for scuba purposes. The technical layout of these units has to be changed for the use underwater. Ted Zarcone and Wayne Journey show you the result of the conversion of these units.
Here are pictures of the Biopak 60 (1974-1975 design) and the Biopak 240 (design 1984) rebreathers, converted for underwater as a MCCR cmf rebreather.
In the middle you see the metering valve that add’s the oxygen to the loop
The BIomarine rebreathers are special because they have a radial scrubber design
Ted and Wayne thank you for contributing to my website. I hope you will be able to send me more details about your build!
Kevin Juergenson thank you very much for the Biomarine History, very interesting read!
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!
