Rebreather Loop
Open to everyone until Thursday, October 1
To keep it, print it while it is open.
A rebreather is a closed breathing system for divers. It sends exhaled gas through a chemical canister that traps carbon dioxide, then returns the remaining oxygen-rich gas to the diver.
In the picture
- Chemical canister filled with granules: absorbs exhaled carbon dioxide.
- Corrugated breathing hose: carries gas between the mouthpiece and the loop.
- Flexible counterlung bag: stores gas and balances each breath.
- Oxygen cylinder valve: adds oxygen consumed by the diver.
Examples
- Submarines use chemical scrubbers to keep cabin air breathable.
- Hospital anesthesia machines absorb carbon dioxide from exhaled gas.
Key takeaways
- A chemical scrubber removes carbon dioxide from exhaled gas.
- Recycling unused oxygen lengthens underwater breathing time.
