Low Profile Particulate Filter

Gentex’s Low Profile Particulate Respirator (LPPR) is a half-mask respirator designed to provide at least 99.97% filtration efficiency against airborne particulates including lead, asbestos, lubricant mist, and explosive gunfire residue

The respirator Includes a fully encapsulated mask microphone which improves communications clarity by reducing the wind noise associated with a standard boom microphone.  It can be configured for all major aircraft intercom systems and portable radios

The front mounted inhalation valves and cartridge ports for an enhanced field-of-vision and a quick one-handed filter change.  Two front-mounted exhalation valves provide easier breathing.

The LPPR seamlessly integrates with NVGs and other eye protection products
