[PSUBS-MAILIST] scrubber filter

[Alan via Personal_Submersibles]

Emile,
l emailed Molecular products in the UK with a question a few years ago, & they 
offered to model what I was doing in their computer. I do not think they have made a calculator available to the public, but were very helpful & have done analyses for military
submarines & no doubt hyperbaric chambers.
   If you are using their product, I am sure they would give you various scenarios
of required flow rates to keep below certain CO2 levels, for the size of your hull & number of occupants.
