Peder Seippel Willie rebreather
Peder Seippel made two rebreathers. He made one rebreather completely by himself.
His other rebreathers is based on the IDA71. Please check his homepage here: http://www.seippel.nu/
The Willie of today is a constant mass flow SCR with back mounted breathing bags. This is how the unit looks with the cover on.
The over pressure dump valve, SI-teck dry suit valve, is seen to the right.
A 5L 200 bar (i.e. 35 cubic feet for you imperial freaks) tank with a Poseidon 1st stage feed the unit. The first stage is ambient referenced thus allowing a slight increase in fresh gas flow with increased depth but also makes it possible to use an ordinary 2nd stage as a bailout, just like the Dräger Ray. The gas to the wing and the dry suit is also feed from this the first stage
The Constant Mass Flow is achieved using a needle valve, from Swagelok, that can be tuned to the flow rate wanted. The valve is located to the left, below the yellow covered hose. The fresh gas is added directly into the inhalation bag using a dry suit inflation valve modified so that it always feeds gas.
Here you find the oxygen cell in the gas path.
Thanks for your Contribution Peder
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!
