Full face mask — silicone material

The face pieces contain no electrical parts, and feature an internal pressure sensor, internal microphone, and a warning light in the user's field of vision
Regulator:
  • Flow capability of peak inhalation air flow in the inner ori-nasal mask of 400 l/min or higher.
  • Breath responsive: air supply continuously adjusts itself to user's air requirements
  • 7—14 mBar supply pressure
  • Easy service — no tools
  • Tested for equivalent of 3 years' harsh condition

User alarms:

The user immediately receives both audible and visual alarms (through a siren and a warning light in the user's field of vision) upon a range of events, such as:

  • Filter change required
  • Low battery power
  • Mask pressure dip
  • Various other system alerts
