The Gentex Low Profile Particulate Respirator (LPPR)

The Gentex Low Profile Particulate Respirator (LPPR) is a half-mask respirator designed to provide protection against a wide range of oil and non-oil based particulate contaminants encountered by door gunners and other rear aircrew during training and in operational environments. Leveraging the technology and design of Gentex’s line of world-leading oxygen masks and respiratory systems, the Particulate Respirator offers 99.97% filtration efficiency against airborne particulates including lead, asbestos, lubricant mist, and explosive gunfire residue. The low-profile design offers protection without interfering with operator’s tactics, techniques, and procedures (TTP) and seamlessly interfaces with weapon systems for optimal effectiveness. The respirator mounts to standard bayonet receivers of the ALPHA® 900 and replaces the boom microphone assembly with a fully encapsulated mask microphone, offering greater communications clarity by reducing wind noise. It Interfaces with all major aircraft intercom systems and portable radios.



Will LPPR protect me from COVID-19 (Corona Virus)?

  • While CDC does not recommend respirators as the first measure for the public to use to prevent the spread of Corona Virus, they do indicate that N95 masks are effective.

“An N95 FFR is a type of respirator which removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3 micron) particles. N95 FFRs are capable of filtering out all types of particles, including bacteria and viruses.”
