MBU-12/P Oxygen Mask


Originally developed by Gentex and Scott Aviation for US Armed Forces requirements this mask is now distributed by Aeromiltec Ltd.


Used with pressure demand systems, the Gentex MBU-12/P boasts a low profile design providing excellent stability during high-G maneuvers and anti-roll webs to prevent downward roll.


Designed to replace the Gentex MBU-5/P, this unit offers superior comfort and efficiency including downward vision. The advanced design of the combination-breathing valve provides greatly reduced exhalation resistance during pressure breathing, and a rolling diaphragm reduces the potential for valve sticking caused by residue accumulation. This unique combination valve meets or exceeds all performance requirements of MIL-V-27296.


  • Low profile design provides excellent stability during high-G maneuvers.
  • Silicone rubber faceseal.
  • Meets or exceeds the requirements of the U.S. Air Force specification MIL-M-87163.
