AMETEK AMERON Receives FAA-PMA Approval for Oxygen Mask MMXM48

BALDWIN PARK, CA (MAY 9, 2022) – AMERON — a brand of AMETEK MRO and global provider of aviation safety OEM and PMA products and third-party repair and overhaul services — has received FAA-PMA approval for its oxygen mask, part number (P/N) MMXM48.

“The MMXM48 oxygen mask was designed to be a direct replacement alternative for OEM oxygen mask part number MXM48,” said Adam Brammer, Divisional Vice President and Business Manager of AMERON. “This alternative solution will considerably help customers that experience long lead times from the OEM.”

The MMXM48 oxygen mask is an integral component of the OEM MF20 series full face quick donning mask regulator assembly, which is an emergency breathing device made for airliner crews that fly no higher than 40,000 ft maximum. When in use, the mask assembly gives protection to the flight crew against effects of depressurization, harmful gases, and fumes. 

AMERON recommends the MMXM48 be inspected by the customer regularly for any damage that may affect the pilot’s ability to see clearly through the mask. If damage has occurred, the customer should make replacements as necessary. AMERON also recommends the MMXM48 be reviewed as part of the full mask overhaul every six years for replacement.
