Rebreather aerodynamics

CCR Liberty has extraordinarily low breathing resistance. Breathing work 1.58 J/l at depth 100 m place the CCR Liberty among the world’s best.

300 m depth

Rebreather was constructed with maximum operating depth 300 m in mind. Every part is tested to 600 m. EC Type-examination was performed to 100 m simulated depth.

CE Certified

The first rebreather in the world certified according to EN 14143:2013 without any exceptions or exclusions.CE Marking

Two years of rigorous testing.

Industrial manufacturing


We manufacture rebreathers in our own facility specialized in technical diving equipment. Only for development and testing purposes were produced about 30 units. Production series are even bigger.
