Gentex LPPR/SOTR mask

The Gentex Low Profile Particulate Respirator is a half-mask respirator designed to provide protection against a wide range of oil and non-oil based particulate contaminants encountered by doorgunners and other rear aircrew during training and in operational environments.


  • Offers at least 99.97% filtration efficiency against airborne particulates including lead, asbestos, lubricant mist, and explosive
    gunfire residue
  • Includes a fully encapsulated mask microphone which improves communications clarity by reducing the wind noise associated with
    a standard boom microphone (5 Ohm, 150 Ohm and mic amplifier for high impedance ICS)
  • Can be configured for all major aircraft intercom systems and portable radios
  • Seamlessly integrates with NVGs and other eye protection products
  • Two exhalation valves for easier breathing
  • Can be worn with head harness or mounted with bayonets to Gentex Alpha 900 and Eagle and HGU-56 helmets
  • Flexible and lightweight silicone face piece with a wide, wraparound, and pleated design to enable the
    respirator to fit to a large variety of facial types
  • Front mounted inhalation valves and cartridge ports for an enhanced field-of-vision and a quick one-handed filter change
