Warren,
I'm still researching my scrubber but here's what I found so far.

I see no need for any valves.  Why restrict the airflow with anything.  What
you want to do is move as much air as you can with the smallest cost in
electricity.  Heck, in the case of a power failure, you can spread the
absorbent material across a suspended screen and fan it now and than.  The
important thing is it move air around the particles of absorbent and keep it
dry.

The quantity needed is a function of the temperature and humidity also.
When relying on it for an emergency situations, you must consider a method
of scrubbing if you don't have battery power.  One person will generate
enough CO2 in 72 hours to require in the area of 50 pounds of SofnoLime.  If
it's cold more, and as the humidity rises more yet.

I'm not finished researching, but that's what I concluded so far.
Corrections appreciated! ;-)
Dan H.
