Hi HughI believe sodasorb v sofnalime is merely marketing name. They are both products based upon soda-lime and should have similar characteristics. Efficiency is going to depend upon many factors unrelated to the physical qualities of the absorbant, including how it is packed, air flow (radial vs longitudinal), size of granules, and air velocity. You don't want the air to move too fast or the latency time will be too short. Also, you'd be better off using a CO2 sensor than watching for color change to determine when absorbant capacity is exhausted.

Thanks Jon and Vance, I have copies of all that but there is nothing on comparison of actual performance of the Sodasorb v's Sofnalime or other suppliers and theiractual absorption and efficiencies of the scrubbers. I have some info from the manufacturers but as the weight is important sobecomes the importance of efficiency etc. Also the fan performance drops off when you blow through the granules and that becomes a bit complicated to calculate. Resistance figures of inches water drop against air speed would be great to have. I will try and contact the suppliers to see if those figures are available. I have this old Comsub and it has a 3" scroll blower which has a fair capacity but is split into parallel lines into two separate packs and by the time it comes out it is fairly gentle. The packs are 8" diameter and about 6" deep. Cant see the granules to check on colour somight try and do a clear window in one of the packs. Chs Hugh
