Enforcer Rebreather sub banner.jpg

Designed to meet the evolving operational roles of maritime law enforcement and special operations, its unique design offers unparalleled performance and mission flexibility whilst minimising size and weight.

The use of pre-packaged ExtendAir® cartridges ensures consistent CO2 scrubbing performance and simplifies
scrubber canister filling, whilst providing low work of breathing, thereby reducing diver fatigue.

Via a first stage pressure reducer, oxygen is supplied from the pressure vessel (cylinder) to a demand valve that automatically adds oxygen to the re-circulation sub-system.

One-way check valves in the breathing hose mouthpiece assembly ensures exhaled breathing gas is re-circulated through the ExtendAir® cartridge that removes exhaled CO2 prior to re-inhalation. A readily accessible submersible pressure gauge enables continual monitoring of oxygen pressure vessel.

ExtendAir® Benefits

  • Extremely low work of breathing
  • Consistent CO2 scrubbing performance
  • No requirement to pack granules manually
  • No user packing variability and greater duration consistency
  • No CO2 absorbent material channelling and early CO2 break through from settling
  • Water tolerant; the hazard of a caustic cocktail is significantly reduced
  • Flooded breathing loop is recoverable allowing a mission to be safely aborted
  • Lack of dust compared to granules (allows canister packing aboard submarines)
  • Excellent shock and vibration resistance
