How Does a Carbon Dioxide Scrubber Work in a Rebreather
Diving rebreathers rely on CO2 scrubbers to keep you breathing easily underwater. These clever devices use a chemical reaction to remove the carbon dioxide you exhale, letting you rebreathe the same gas supply for extended periods. The magic happens when your exhaled breath passes through a canister filled with soda lime, a mixture of calcium hydroxide, and other compounds. As the waste gas flows through, the soda lime grabs onto those pesky CO2 molecules. The calcium hydroxide reacts with the CO2 in the breathing circuit to form calcium carbonate, which is retained within the absorber unit. This process effectively scrubs the breathing gas clean, allowing the oxygen to be recycled and reused.
Large kegs of CO2 scrubbers, like our Intersorb 812 45lb offering, pack a serious punch. They contain enough soda lime to handle hours upon hours of diving, making them ideal for technical divers and those planning extended underwater adventures. The sheer volume of carbon dioxide absorbent material means you can trust your gas supply to stay clean and breathable, even on the longest and deepest dives. The chemical reaction continues steadily as you explore, constantly removing CO2 from your exhaled gas and keeping your inhaled gas mixture safe and comfortable.
How Much CO2 Do Scrubbers Remove
CO2 scrubbers are remarkably effective at cleaning your breathing gas. A high-quality absorbent like Intersorb 812 can remove nearly all the carbon dioxide from your exhaled breath, typically reducing CO2 levels to less than 0.1%. This means that over 99.9% of the CO2 you exhale gets captured and removed from your gas supply. The efficiency of the scrubbing process depends on factors like the gas flow rate, the temperature, and the specific absorbent material used.
As divers breathe, they produce about 4-5% CO2 in their exhaled gas. Without a scrubber, this would quickly build up to dangerous levels. However, with a properly functioning CO2 absorbent, the levels of the inhaled gas stay well below 0.5%, often much lower. This powerful cleaning action allows divers to recycle and reuse their breathing gas for extended periods. A 45lb keg of high-quality scrubber material can last for many hours of diving, efficiently removing CO2 throughout your adventure. The sodium hydroxide and other compounds in the scrubber continuously react with carbon dioxide, forming sodium carbonate and other byproducts, keeping your diving gas mixture clean and safe to breathe.
