MX Rebreather - Diluent feed and ADV

As discussed earlier the diluent block is stowed on the right chest ensuring that it can be reached with either hand. We also feed this block directly with the largest source bailout/diluent gas, or bottom gas. Remember we use standardized mixes so this would have the lowest O2 and highest HE of all the gases we are carrying for bailout. We feed it from the right post, as it is the “Primary Post,” standard UTD/DIR philosophy, but this also means that it is on the opposite post to the backup dil feed which is the left post. Remember as a backup procedure of adding dil, we connect the BOV regulator and can add gas diluent from the BOV mouthpiece. As discussed earlier we also put an isolator on this primary dil feed hose to ensure that if the dil block was to fail “open” we can isolate it - shut the supply off - without shutting off the post or giving up the donate-able long hose, kept o

n the same “primary” first stage.

The MX-KISS is offered with the stock ADV, or auto diluent valve. This is a simple tilt valve positioned out of the slipstream of the unit and allows the user to draw dil into the rebreather whenever the loop pressure is negative. The ADV is connected to the left post to add redundancy in the event of a right post failure.
