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.

- The 797 Grade, CD Grade, and Military D Grade ship in high-density polyethylene
(HDPE) resealable containers with 44 lb (20 kg) of product inside.
- Containers can maintain proper absorption capacity for 5 years. Each container
marked with an expiration date
- Sofnolime is shipped as ordinary non-hazardous product
- High attrition resistance (low dust formation)
- Follow your rebreather manufacturer’s recommendations for scrubber change
intervals
- Only use the specific absorbent recommended by your rebreather manufacturer
- The use of improper absorbent can cause excessive work of breathing and shortened scrubber times
