Well here it is in all its glory...
The blue tank is a .7 litre 200 bar unit.
The white thing is the scrubber cannister which holds about 1kg of sodalime. These are usually a single use item with the RG's but this has already been modified to a refillable one.
Underneath the tank is the regulator unit. Its job is to supply a contstant .8l flow of O2 into the system regardless of depth. It does this by droping the pressure down to about 70 psi (5bar) and using a CMF (constant Mass Flow) sonic oriface similar to what KISS rebreathers use.
The reg also has a OPV and a IP adjustment and also a manual add button to inject a little more O2 when needed.
Exiting from the top of the scrubber is the breathing hoses and the horse shoe shape counter lung.
All in all its a pretty simple system as most O2 rebreathers are.
Dave Ray (who has built RBs in NZ since the '80s) has kindly offered to join me in the pool for a test dive. He also owns a RG.
Also included was a second regulator system (I think it may be damaged)
A trans fill whip, some tools, Sodalime and various other odds and ends.
My goal is to add a offboard dilutant tank and PPO measurement and turn it into a mCCR with OC bailout. And be able to dive it to 30 meters. The scubber and O2 tank should be good for about 2 hours I think.
Not bad for a $360 trade me deal aye!!
