Aviation Respirator for Flight Helmets– with built-in microphone! 

Unlike other respirator masks, this one comes with a civilian microphone built into the mask to maintain communications. Made from soft, flexible silicone for a comfortable, conforming fit, this respirator features high quality breathing protection from fumes and spray product particulates including ammonia, chlorine, mercury vapor, and many other hazardous aerosols. It can also be used for protection against smoke inhalation (does not protect against carbon monoxide). Available in size small, medium, or large with the choice of strap setup to accommodate most helmet types (including all HGU and SPH helmets). The respirator mask includes: mask, microphone, helmet strap assembly and bayonets, standard mic cord to plug into helmet (same location that boom microphone would plug in), 2 filters, N95 pre-filters and pre-filter cover that can be used instead of regular filter or in addition to regular filter. Replacement filters and pre-filters are available as needed (purchased separately).

Product Features

FlightHelmet.com’s aviation respirator mask is built using an NOISH approved industrial respirator
mask and converted for aviation use by manufacturing and installing a civilian impedance
microphone and replacing the industrial elastic head harness with a web strap assembly and
attachment hardware specifically designed for aviation flight helmet use and designed to maximize
the ability to interface the mask with a variety of flight helmets. The strap
harness is unique only to FlightHelmet.com’s aviation mask products and a key feature that allows
the mask to be used with SPH helmets in addition to HGU helmets. Simply mounting attachment hardware on this style
respirator mask’s industrial head harness elastic straps does not provide an adequate pressure to
hold the mask against the face for some flight helmet types. The FlightHelmet.com web strap
assembly moves the attachment points forward on the mask to allow more range of adjustment and
allows applying more pressure holding the mask against the wearer’s face. The component features
are the following:

- Uses standard commercially available screw on filters and pre-filters, which are available in different
types, to provide protection in a variety of environments/hazards.
- Masks come with filters and pre-filter assembly, but can
be used with other screw on filters/filter assemblies.
- Industrial talk-thru diaphragm is replaced with aviation microphone assembly that integrates
David Clark M7A civilian impedance microphone via microphone cord with NEXUS U173
plug to existing NEXUS U172 microphone jack available on most flight helmets
- Standard industrial head harness is replaced with specially designed strap harness and
bayonet fittings to attach to most flight helmets, including SPH-5. Strap assembly is
manufactured with the same mil-spec webbing, buckles, and bayonets as used on military
MBU-12 oxygen masks
- FlightHelmet.com’s aviation respirator mask including the aviation microphone assembly,
and flight helmet strap harness design has already been successfully installed on and used
with SPH series helicopter flight helmets for use in the Agricultural Aviation Industry
- FlightHelmet.com’s flight helmet strap harness design has also been used on similar masks as an oxygen mask on fixed wing flight helmets
- Aviation microphone assembly has been FAA CAMI tested for use with a similar mask as an oxygen mask up to 30,000ft in altitude
