Specifically designed for the B777, our lightweight and durable Gaseous Passenger Mask Dispensing Unit P25048/P25049 is designed to deploy automatically two (2) or three (3) TSO-C64a certified constant flow oxygen masks via remote electrical actuation (115 VAC) of a solenoid latching mechanism in the event of cabin decompression.  By pulling the mask down, the passenger is removing the pin from the valve assembly, which triggers immediately the calibrated flow of oxygen to the mask. 

Designed to fit most custom interior headliners, crew rest areas, lavatories and galleys.
