Hello Dragan,

The offboard will feed all system i.e. Manual Feed, ADV & BOV for DIL and Manual Feed & Solenoid for the O2 side.

The only issue with BOV is the fact that the Sentinel & Boris use QC4 Swagelok for offboard connection, which acts as a flow restrictor. The BOV is only to be used as a sanity breathe in other words 1-2 breathe before you switch to external bailout. You will have to experience the flow restriction at different depth, it obviously depends on the mix you are using.

On my Boris I am using Swagelok QC6 for the offboard, it has a bigger flow!

Cheers

Thanks!

QC6 is the connector I've been thinking of using as well.

Did you get the QC6 as an option from CCRB, or did you mount it by yourself after delivery? Do you know if it's available as option for Sentinel?
