What is a Rebreather

The rebreather is a simple system used to recycle the exhaled breath during ventilation, in particular the oxygen that otherwise would be wasted in the external environment.

Metabolic consumption of oxygen with every breath is about 4% and the remaining is exhausted into the surrounding environment.

During breathing, the carbon dioxide we produce is eliminated by passing through a filtering material to prevent the diver from breathing it again.

All type of scuba rebreathers consist of two systems: one of breathing and one of feed.

Here below are the main feed systems:
  • Manual system;
  • m-CCR (mechanical controlled close circuit rebreather);
  • e-CCR (electronic controlled close circuit rebreather).
  • Hybrid CCR
