SE400AT-2 Data Sheet


      All the air you need
      The SE400 gives you true positive pressure air up to and in excess of 400 litres per minute. Conventional fan-assisted respirators give you a mere 120-180 l/min.
    • Big savings on filters
      The SE400 is not a continuous-flow respirator. Air passes through the filters only as you need it. That’s why the SE400 uses 50% less filters on average, compared to other fan-driven respirators.
    • Know what’s happening
      With the SE400, you will always know that you are getting the protection you need. Visual and audible alarms alert you to any routine task (such as changing the battery), as well as other events that may require your attention.
    • Communication
      Voice transmission is loud and clear. SE400 comes with a microphone in the mask and a powerful external loudspeaker.
    • Single button operation
      Put it on. Breathe. It couldn’t be easier.
    • Wear it the way you want
      The SE400 can be worn on a backpack, waist harness or standard belt. Fit the hose over your shoulder or around your side.
    • Suitability
      The SE400 can be worn inside suits of various materials, ranging from disposable dust suits to fully encapsulated gas suits. All suits can be pressurized by the SE400.
    • Hi-tech operation
      Micro-processor driven fan operation
  • Continuous self-diagnostics
    Instant user alerts in case of pressure-drop, motor malfunction, low batteries etc.
