C21 CLOSED AND SEMICLOSED CIRCUIT REBREATHERS

ONLY HIGH TECHNOLOGY DIVING

C21 is the evolution of C21 C-96 rebreather originally designed by Bruno Marchetti (San-o-Sub founder) with the support of qualified companies, which is widely used around the world by professional and military users. C family is C-96 state-of-the-art version characterized by the cutting edge technology for light closed circuit diving systems, ensuring high level of performance, low magnetic and acoustic signature, stability and reliability. C21 is available in the following configurations:

  • C21 (upgraded C96): A compact manual frontal oxygen unit excellent for training
  • C22: A compact automatic frontal oxygen unit
  • C23: An integrated and automatic front-back unit including buoyancy compensator and allowing both nitrox and oxygen use with possibility to switch between the two gases during underwater operations, as required.
  • C20: A compact automatic back mounted oxygen unit, specifically designed for divers having to use underwater scooters or crafts.
    C21 has a radial scrubber of the highest efficiency and is fully mechanical therefore it is simple to operate, ultra-light, reliable and requires very little maintenance (no battery, electronics or sensors to replace). It is designed to operate in shallow dives using pure oxygen or Nitrox mixes.
