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.

The 797 Grade has a small particle size (1.0mm to 2.5mm) and has a triangular cross-section, which combine to give a high CO2 absorption capacity.
