FirePASS is a fire prevention and suppression system that works by limiting one of the components of combustion: Oxygen. It uses Hypoxic (oxygen reduction) technology to provide proactive and permanent fire protection.

The resulting air is breathable low oxygen air – no nitrogen injection. There is no damage by water, foam or extinguishing agents which is a major disadvantage of other firefighting and prevention equipment.




FirePASS FP-5000 to FP-20000

How it works

  • Ambient air is drawn into the hypoxic generator where it is purified and turned hypoxic (low oxygen level).
  • The entire room is ventilated with low oxygen air, inhibiting fire ignition.
  • Low oxygen air leaks from the room, thus completing the flow of air and ventilating the space.
  • A control unit monitoring the room with oxygen-sensors permanently ensures a stable and healthy low oxygen environment in the room.
