I don't know anywhere online. I have asked the Katadyn folks for some technical information and hopefully will get a response before too long, though it may be next week given it's already Friday.

Thanks, Doug!

I always seek to learn...and I also want to make sure there's no misinformation in my report on backpackgeartest.

Hey, I could be wrong too, though I did research this previously. Wouldn't be the first time and unlikely to be the last. <img src="/images/graemlins/grin.gif" alt="" /> We'll get it straight, one way ot the other.
