E06Crew & passenger oxygen

Provide oxygen through designated supply systems.

Manufacturers & products

Passenger decompression oxygen, flight-crew breathing systems and protective breathing equipment serve different purposes. Compare within the product class and retain the exact approved aircraft configuration.

Program applicability is stated for each listing. 737NG, 737 MAX, and other aircraft examples are distinct configurations; listed products are not automatically interchangeable or approved for installation.

Custom program inquiry

Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.

Product scope & qualifications
  • Manufacturer cites STC certification but the sheet does not identify its number or aircraft applicability list.
  • Published 15-year durability is not oxygen delivery duration.
View product & inquiry route

What remains unverified

  • Aircraft-specific mask counts, generator output profiles and approved part-number effectivity are not fully public in these sources.
  • No claim is made that a general oxygen-family product is interchangeable with the 737NG original installation.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Equipment class

    Separate chemical generators, stored-gas systems, crew demand regulators and smoke hoods.

  • Aircraft effectivity and approvals

    Use the exact approved part number and installation documentation, including STC effectivity when applicable.

  • Delivery duration and operating condition · min

    Emergency oxygen runtime depends on equipment class and specified conditions.

  • Capacity and users supplied

    Define oxygen quantity, flow regime and mask count; capacity alone does not determine duration.

  • Service life and maintenance interval · years

    Distinguish shelf/installed life from oxygen delivery time.

  • Mass and installation envelope · kg

    Include brackets, hoses, masks and required protective packaging.

  • Interface and activation provisions

    Assess installation connections and required maintenance controls through approved data.

  • Traceability and logistics

    Life-limited articles and oxygen-generating materials need supplier-supported identity and handling records.

Selection & integration notes
  • Never compare a 15-year service-life claim with a 15-minute breathing-duration claim.
  • The manufacturer pages provide inquiry starting points; approved maintenance data governs installation and replacement.
