I have been tearing apart a meg today and Ive noticed something I didnt think of before.


The cells are screwed in from the exhale side and the sensor faces are on the inhale side.

So the cells have to seal into the cell holder in order to stop bypass (from inhale direct to exhale missing the scrubber)


Even though I didnt like the cell being a 'seal' or the fact there would be a temp and gas difference across the cell I figured well the sensor thread is a good fit in its holder so the seal would be good enough.

But then I thought about the 3 most recent cell failures Ive had. As reported before I had three cells fall apart in use in an unusal way where the body of the cell parted from the faceplate (bit that screws into the holder) Now Im thinking what would happen if that had happen to me on a Meg??? There effectively would be a direct hole from the inhale to the exhale side of the loop!!

hmmm.

Not sure thats a good design. I dont like the idea of the glue that holds the cell to the cells faceplate being the seal between inale and exhale. A bypass there I guess could be very nasty.
