my Meg and Draeger FFM, sweet!

Hey buddy,

How're you and Patty doing???? I hope you guys are doing fine up there.
Do you know the model or code number for the Nova FFM for CCR??? I don't want order one and arrive the wrong one (SCR or OC model).
I hope see you down here this year.
Cheers,

I imagine that the spring pressure is high so one wouldnt vent gas without knowing it. If one hooked up an OC reg for bailout, you would use the existing exaust valve on the OC reg for exhaling and only use the bottom vent to dump water from the mask, course if that is the case, on OC you would have to block the OC vent somehow so you could blow water out.

Mike, I dont know the exact part number, but try www.danshop.com, the website is in german but I imagine matt can help you find the right part number.

this is the link to the mask on danshop. I ordered the apeks second stage for my mask from these guys, expensive but good service.

we are coming down to see you in January, dave and i are doing our ccr cave with matt, you could probably convince Patti to do a cavern course.

dreager makes this mask in OC form as well as the CCR (or SCR) version. There is a specific DSV to use with the Ray or Dolphin (and probably the LAR-5 too) with the P -port on the diver end instead of a mouthpiece.

Dräger makes FFM DSVs for all their military and civilian rebreathers.
IIRC Stanton's mask at DEMA had the FGT DSV attached to his Meg's hoses.
Picture is somewhere in the gallery.

this mask is specifically for rebreathers, the difference is in the mouthpiece that projects inside the mask for the diver to grab and hold in the mask, this keeps the mask volume from becoming part of the loop and trapping CO2.

The part below is what differenciates the rebreather mask from the OC mask.
It's also available as a part from W+S Water Safety (danshop) in Germany.

I was looking at one of these at LIDS and talking to the Apeks guys about it.

Apparently the 'unofficial' solution to bailout is as follows. Attach the 2nd stage to one of the side ports, and use a flow stop to prevent gas flow, to solve the OC exhaust problem, remove the exhaust tee and block off the exhaust diaphragm on the 2nd stage. Meaning that the exhale in OC would vent out of the bottom.

I'm not sure I like the solutions and would much prefer a BOV.

Cheers

Rich

I thought about this, if you were to become unconcious due to o2 tox or hypoxia and the mouth gag remained in-place would you not start to nose breath natrually and therefore take (safe) gas fron the oc reg? If this is the case then it would be a safer solution to someone who dives alone, sort of "automatic bailout"

according to the aqualung guy in france (not a representative, but aqualung himself :-) you always put a flowstop in line with the OC regulator you connect to the mask..

any idea why?

My thoughts exactly and precisely why I have just ordered one, unfortunately there seems to be a bit of a run on them and it won't be available before next month though.

I think this type of mask/set up needs the bailout reg (normally and in the first instance) to be plumbed into a bail gas that is the same as the dil gas. In this way the 2nd stage acts just like the units ADV. [By breathing through the nose you can add dil also]. In this way if the 2nd stage free flows its no different to an ADV freeflowing.

Havent got mine yet but this is how I figured Id work it.
