rEvo III Closed Circuit Rebreather - POA

Experience Silent Diving with the rEvo iii Closed Circuit Rebreather

The rEvo III mCCR is a manually operated closed circuit rebreather based on the CMF 
principle: (constant mass flow). During diving a constant flow of oxygen bleeds into 
the breathing loop of the rebreather. The flow rate is high enough to provide a diver in 
rest with a life sustaining breathable oxygen flow. The flow rate can be adjusted to the 
individual metabolic rate of the diver. But it is kept low enough to be safe. During the 
dive the diver controls and monitors their PPO2 with the help of the LED-indication of 
the HUD and their handsets: when needed they can manually add oxygen through the 
oxygen addition valve to maintain the desired PPO2.

It must be clear that the standard rEvo III mCCR is not an electronically controlled 
rebreather: there is no computer which decides when oxygen has to be added: that is 
the role of the diver. 

The rEvo III hCCR (non-rMS and rMS) is a fully automatically operated closed circuit 
rebreather, where the O2 addition is also supported by a constant mass flow orifice: in 
case of malfunction of the automatic control system, this CMF allows to operate the 
rebreather identical to a standard mCCR.

Easy to setup, easy to transport, easy to dive and easy to maintain:

The rEvo III mCCR has been designed with one clear purpose in mind: simplicity in 
setup, simplicity in use and simplicity in maintenance. The user has access to all 
rebreather parts. Oxygen cells, ADV, orifice, scrubber-canisters, moisture pads can be 
reached by demounting the main cover, removing one screw. 
 
This unique design means that the rebreather has only 4 connections with O-rings 
used by the diver: 2 for the breathing hoses and 2 for the main cover: the scrubber 
lid (each with a double o-ring). The risk of leaking, wrong connections, wrong 
assembly and forgotten o-rings has thus been reduced to a minimum! .
