<strong>MBU</strong>-<strong>12</strong>/P <strong>Oxygen</strong> <strong>Mask</strong><br />
The <strong>MBU</strong>-<strong>12</strong>/P meets or exceeds the requirements<br />
of U.S. Air Force Specification MIL-M-87163.<br />
The <strong>MBU</strong>-<strong>12</strong>/P mask is designed to replace the<br />
<strong>MBU</strong>-5/P and offers substantial improvement in<br />
comfort and efficiency when compared to the older<br />
mask. The <strong>MBU</strong>-<strong>12</strong>/P features a gray silicone rubber<br />
faceseal integrally bonded to a high strength gray<br />
polysulfone plastic hardshell.<br />
The shape of the <strong>MBU</strong>-<strong>12</strong>/P mask provides excellent<br />
downward vision. The low profile design brings the<br />
mask close to the face and provides excellent stability<br />
during high G maneuvers. Anti-roll webs at the nose<br />
seal prevent downward roll off. The inherent rigidity<br />
of the integral faceseal/hardshell allows adjustment<br />
to provide superior sealing during pressure breathing.<br />
Four mask sizes are available to assure proper fit and<br />
comfort.<br />
The unique design of the Gentex developed<br />
combination breathing valve distinguishes the<br />
Gentex Model of the <strong>MBU</strong>-<strong>12</strong>/P. Using concepts<br />
developed during the space program, this valve offers<br />
greatly reduced exhalation resistance during pressure<br />
breathing. Additionally, the rolling diaphragm reduce<br />
the potential for valve sticking caused by residue<br />
accumulation. The combination valve meets or<br />
exceed all performance requirements of MIL-V-27296.<br />

Accessories and options<br />
AM-7067A Audio Amplifier<br />
A carbon compatible audio frequency preamplifier<br />
to permit use of dynamic mask microphone with<br />
carbon-type radio systems. Suitable for use with the<br />
<strong>MBU</strong>-<strong>12</strong>/P oxygen mask subassembly to interface with<br />
an M-94B/A or M-101/AIC dynamic microphone with the<br />
US Navy intercommunications system. The amplifier is in<br />
accordance with MIL-M-23595 and in general accordance<br />
with 765AS287.<br />
Gentex carries all of the necessary tools to support<br />
maintenance of the <strong>MBU</strong>-<strong>12</strong>/P oxygen mask. Each<br />
is available for individual purchase.<br />
Performance<br />
Tear Resistance<br />
The silicone rubber used in the manufacture of the<br />
<strong>MBU</strong>-<strong>12</strong>/P has a minimum tear resistance of 26269<br />
newtons per meter (150 pounds per inch).<br />
Toxicity<br />
The silicone rubber used in the mask assembly does<br />
not contain any chemicals or materials that have toxic<br />
properties.<br />
Dielectric Strength<br />
The microphone connector withstands without flashover<br />
or breakdown, the application of a 250-volt alternating<br />
potential of commercial line frequency.<br />
Combination Valve<br />
Meets or exceeds the requirements of MIL-V-27296.<br />
Superior exhalation resistance compared to requirements<br />
as follows:<br />
