John build his own LAR rebreather using parts from RG/UFM and homebuild
The unit has the same functional
princples. It is based on a demand system and can be bypassed
manually. For the oxygen addition the CL is mounted on a demand
regulator thas has been found in a scubapro second stage. To
prevent the counterlung form collapsing it is equipped with a
stainless spring. A nice and simple design.
The counterlung is made of plastic but

In the center you see the manual bypass. It is operated by
pressing the membrane.
The membrane and lever are build in a polyamid housing
