DILUTER DEMAND CREW MASKS:
Required equipment for any civilian factory aircraft with service ceilings above FL250 to FL 440—whether pressurized or unpressurized.**

DILUTER DEMAND CREW MASKS

are required equipment for any civilian factory aircraft with service ceilings above FL250 to FL 440—whether pressurized or unpressurized.**

PRESSURE DEMAND CREW MASKS

are required equipment for any pressurized civilian factory aircraft with service ceilings above FL450.

CONSTANT FLOW CREW MASKS

can be used for supplemental oxygen in any civilian factory aircraft with service ceilings below FL250.

OXYSAVER CANNULAS (constant flow) can be used for supplemental oxygen in any civilian factory aircraft with service ceilings below FL180. Enjoy up to eight times the duration from your tank—built-in or portable—over the use of ANY mask.

**EXCEPTIONS. Many EARLY UNPRESSURIZED civilian factory aircraft (Cessna & Piper) are still in service—with service ceilings to FL350— which have been Grandfathered for the continued use of their original Constant Flow Crew masks. A partial list of grandfathered aircraft is below. However, most if not all owner operators of these aircraft have upgraded their grandfathered equipment to the DILUTER DEMAND CREW MASKS. If you need assistance in replacing your constant flow equipment, contact info@aviationoxygen.com with images of the oxygen connector/mic—and aircraft make, model, service ceiling.

NOTE: The FAA is currently studying whether crew masks—for ALL aircraft with service ceilings above FL250 - should also be SMOKE-VENTING TSOC99A. If you are unclear about whether or not your existing diluter/pressure demand equipment meets this TSO, please send the PN of your crew masks to info@aviationoxygen.com. [This is already a requirement for Canadian pressurized aircraft.]
