[PSUBS-MAILIST] scrubber performance

[Cliff Redus via Personal_Submersibles]

Your scrubber meets ABS rules which requires the CO2 concentration to stay
below 5000 ppm (1/2%) .  From my own experience, I found that the type of
fan and the flow orientation makes a big difference in how low the scrubber
can pull the CO2 concentration down to.  Specifically, squirrel cage
blowers work better than axial fans and radial flow works better than axial
 flow through the Sodasorb HP.

I am proud of your mom.
