Frequently Asked Questions (FAQ)
Q: What is the difference between Sofnolime 797 and 408? A: The primary difference is the granule size. 797 is a smaller mesh (8-12 mesh / 1.0mm to 2.5mm), which provides a higher surface area for CO2 absorption. This makes 797 the standard choice for most modern closed-circuit rebreathers (CCR).
Q: How should I store my Sofnolime keg once opened? A: Always ensure the lid is snapped shut tightly to maintain an airtight seal. Store the keg in a cool, dry place ( to ). Avoid direct sunlight or freezing temperatures, as moisture loss can reduce the efficiency of the absorbent.
Q: How do I know if the sorb is "spent" or "fresh"? A: This is a Non-Indicating sorb, meaning it does not change color. You must track your scrubber usage in your dive log based on your manufacturer's recommended durations and your dive conditions (water temperature and workload).
Q: Is this product compatible with my rebreather? A: Sofnolime 797 is the factory-approved absorbent for the majority of technical rebreathers, including the AP Diving Inspiration/Evolution, rEvo, JJ-CCR, Poseidon, and Hollis units. Always consult your unit's manual for specific packing instructions.
Q: Does it have an expiration date? A: Yes. Each keg is marked with an expiration date. Most of our kegs last more than most relationships. At Gulf Coast Scuba, we rotate our stock often to ensure you receive the freshest batches available.
