Re: [PSUBS-MAILIST] A question on rebreathers and scrubbers

[Warren Greenway <opensourcesub@yahoo.com>]

As small as possible while allowing the desired CFM
to flow through the desired surface area. I got good
air flow with 1mm size granules. The granules I was
using presented more surface area then a crushed
granule would, however, since it was built of of many
smaller bits and had a very rough surface. Note, also
that straight finely crushed lime would be more
durable
and require a coarser filter (a good thing).
