The 797 Grade has a smaller particle size (1.0 to 2.5 mm) and has a triangular shaped cross-section, which combine to give a higher CO2 absorption capacity compared with CD Grade. The 797 Grade is the one most widely used in modern rebreathers. It is generically referred to as “8-12 mesh” or simply “812” by divers because the granule sizes are similar to the apertures found in size 8 wire mesh up to apertures found in size 12 wire mesh. Manufactured by Molecular Products in the U.K.
