Flex CCR is robust, compact exploration rebreather.
It is approximately size of an aluminum 11L/AL80 cylinder. The unit is completely self-contained with the exception of oxygen and diluent gas supplies.
Flex can be either configured as an mCCR or eCCR.
Base Platform
In the default configuration, Flex comes with following:
Scrubber Can w/5lbs radial scrubber, fenestrated CL cover tube w/removable door, 3D counterlungs with dump valve and bayonet connectors with snorkels, head (incl. watertight cable connectors) with removable sensor carriage, Top Lid with ADV w/integrated MAV ports and hose bayonets and nipples.
Additional components and electronics packages are added to this platform to configure the unit to your specific requirements.
Gas Path
BOV
Sidemount DSV
Starting at the mouthpiece (either Golem Shrimp BOV or DSV with 90 degree adapters or dedicated Sidemount DSV) , exhaled gas leaves the mouthpiece and flows down into the top of the unit. Where the corrugated breathing hose enters the top plate of the unit through a bayonet connector, a Miflex hose enters next to the bayonet. This supplies oxygen from the manual add valve, which enters the loop just below the breathing hose bayonet. This means the O2 must travel through the rest of the circuit before being inhaled, giving plenty of time for adequate mixing before passing over the O2 cells and being breathed.
Top plate with hose bayonets
Gas then enters the exhale C/L immediately below the top plate. This C/L contains an OPV/dewatering valve, which can also be manually activated via a drawstring. After the exhale lung, gas passes through the rebreather head and down into the outside of the scrubber can, before entering the scrubber from outside in.
Counterlungs
Gas enters the scrubber then passes up the inside of the scrubber to a chamber containing the 3 oxygen cells. The oxygen sensors are in removable cartridge/carrier that can be easily detached for storage in a dry place.
CMF/Leaky Valve
Past the cells, up into the inhale C/L, gas then leaves the unit via the inhale hose to the diver. Again, at the point where the inhale hose attaches to the top lid there is another Miflex hose which delivers diluent via the diluent manual add valve. At the head, two other Miflex hoses are seen entering via a radial slot. These hoses supply O2 to the “leaky”/CMF valve or solenoid and diluent to the diaphragm based ADV located under top of the lid, its purge button accessible from the front of the unit.. Two hoses come from the oxygen block (CMF or solenoid valve and manual add) and two from the diluent block (ADV and manual add). The gas supplies could be configured in a number of ways and supply to both drysuit and wing also needs to be considered
