Diving grade Sofnolime absorbs carbon dioxide ensuring a breathable atmosphere is maintained. It is optimised for the removal of carbon dioxide from recirculated air/nitrox/heliox in rebreathers and saturation dive systems, commercial and leisure diving rebreathers, dive chamber/bell scrubbers/gas reclaim systems and dive gas conditioning units.
Two grades are available, 797 Grade and CD Grade. The main differences between the two grades are particle size and shape. CD Grade is a 2.0mm to 5.0mm extrudate with a D-shaped cross-section. The 797 Grade has a smaller particle size (1.0mm to 2.5mm) and has a triangular cross-section, which combine to give a higher CO2 absorption capacity compared with CD Grade.
