How do rebreathers remove co2?
The common way to remove CO2 from a diver’s rebreather is by chemical absorption (“scrubbing”). Most modern commercial absorbents consist of a mixture of calcium hydroxide and sodium hydroxide. Superoxides are used in some rebreathers. They work by absorbing CO2 and releasing O2.
What is diluent in rebreather?
The job of the diluent is to dilute the oxygen to lower the PPO2 at depths greater than 6 meters. The most common diluent used for rebreathers is air. For deeper dives beyond the recreational range varying mixes of trimix are used for the diluent.
Can you use a rebreather forever?
Note. For rebreather, dive duration doesn´t depend on ability to supply oxygen. Even quite a small oxygen tank will last really long. For example, 2-liter tank at 200bar pressure contains enough oxygen for some 6-8 hours dive.
How long does a rebreather scrubber last?
A single fill of a small gas cylinder or cylinders and CO2 scrubber can last for anywhere from one to six hours, depending on which rebreather it is. Unlike open-circuit scuba, your gas duration on a rebreather is nearly independent of depth, so you could, in theory, spend all that time on the bottom.
