Passenger oxygen systems


Passenger oxygen systems

The result of proven system integrator experience, Safran Aerosystems oxygen systems offer a complete range of innovative solutions, including oxygen generation and distribution systems and passenger oxygen regulation systems.

Passenger oxygen generation and distribution

Passenger Oxygen Systems

Hi-EFF® chemical oxygen generation solutions

Chemical oxygen generators are the optimal solution in the event of an emergency aircraft descent. Designed for one to four people, Safran Aerosystems Hi-EFF® solid-state generators are small and light to meet the constraints on board commercial aircraft.

Passenger Oxygen Systems - MDS

Oxygen mask deployment system

The Safran Aerosystems passenger mask deployment system uses detachable cartridges mounted on a manifold plate for seamless integration and unparalleled aesthetics. Easy to test and maintain, it is also reliable and hassle-free. It can be mounted at various angles with single, double and triple mask configuration options available.

Passenger Oxygen Systems - Drop Out Box

Gaseous or chemical oxygen drop-out-boxes (DOB)

Safran Aerosystems offers a full range of customized gaseous drop-out boxes, including low-profile boxes and quick disconnect fittings, with a variet latching, mask ejection and mounting styles. The Safran Aerosystems offer also includes a wide range of integrated chemical oxygen distribution system containers that ensure immediate oxygen availability without requiring high pressure.

Passenger Oxygen Systels - LAVOX Cylinder for toilets

Safe and reliable oxygen solutions for lavatories

Designed to comply with FAA AD 2012-11-09, the Safran Aerosystems LAVOX® cylinder assembly provides oxygen to passengers occupying the lavatory during a cabin depressurization event for up to 22 minutes. Safe, reliable and easy to install, it is compatible with Hi-EFF® passenger masks and fits into existing lavatory DOB

Passenger oxygen regulation

Système oxygène passager - unité de control EFCU

A wide range of control devices to regulate passenger oxygen

From the ultra-precise remote oxygen regulator to the electrical override enabling the pilot to control the oxygen flow mode, Safran Aerosystems offers a wide range of control devices to regulate passenger oxygen. Controlled by discrete signals from an oxygen cockpit panel, software-free, Electronic Flow Control Unit (EFCU) controls the automatic deployment of passenger masks without the need for software, optimizing regulation at all altitudes in compliance with FAR requirements.
