| I actually have one of the draeger FFMs in my possesion, I found one of three in the USA at DEMA last year and want to plumb it to my meg. the problem is the ffm has a draeger P port for an attachment system, so I need a DSV that will fit the meg hoses and also has a P port for a mouthpiece. Draeger sells a DSV with P port but it only fits dolphin hoses. I am working with ISC to machine up the proper part but its slow going as they are so busy building meg's.
One of the big issues with using ffm's with a rebreather is CO2 buildup in the mask, you must have a mouthpiece to breathe from so the mask doesnt become a counterlung on your face. The draeger mask has this covered with a retractable mouthpiece on the inside of the mask, just let go your lips to use comms and then reach out with your lips to regrasp the mouthpiece. the unit also has a neat pair of clamps that look a bit like winshield wipers you use to pinch your nose for clearing. The mask is very comfortable and I have some great anti fog, but still havent been in the water with it.
