Description

G1 ExtendAire II System

The all new MSA G1 ExtendAire II System is an Emergency Breathing Supply System (EBSS) accessory that uses intermediate pressure air to provide firefighters with emergency breathing air.

The G1 ExtendAire II System allows firefighters to quickly and easily interconnect to a fellow firefighter’s air supply. The ExtendAire II System integrated into the G1 SCBA, providing unrestricted mobility and easy access during emergency situations. The system uses locking quick-connects with integrated check valve that prevents contamination of the breathing air pathway by the ambient atmosphere. The new MSA G1 ExtendAire II System features an integrated rescue hose and manifold assembly that uses both male and female quick-connect fittings. The system is stowed in a low profile pouch that mounts on the carrier assembly, positioned to prevent snagging and accidental opening.

The MSA G1 ExtendAire II also provides an airline solution for quick connection at any emergency event requiring an extended air supply like bucket operations, Hazmat or confined spaces. An airline adapter connects to the ExtendAire II manifold assembly, to provide external air from distances up to 300 feet away.

What does the MSA ExtendAire II conversion kit 10156464 add to a G1 SCBA?

MSA part number 10156464 is the ExtendAire II System Conversion Kit for G1 SCBA (2013 ed.), a field upgrade that adds MSA’s buddy breathing system to an existing G1. MSA describes it as an Emergency Breathing Supply System (EBSS) accessory that uses intermediate pressure air, so a firefighter can interconnect to a fellow firefighter’s air supply through locking quick-connects with an integrated check valve.

From MSA’s NIOSH notes: assembly 10158625 (ExtendAire II) “is packaged as a conversion kit as 10156464” and is listed as a component of NIOSH approved G1 configurations.

How do you add emergency and airline air to a G1 SCBA for confined space work?

MSA lists confined spaces, bucket operations and Hazmat as uses for the ExtendAire II airline solution: an airline adapter connects to the ExtendAire II manifold to supply external air from distances up to 300 feet away. The adapters are separate MSA parts (10188834 through 10188847) labeled UEBSS, so confirm the adapter for a 2013 edition kit with MSA.

Escape-only after buddy breathing: MSA’s NIOSH approval matrix for the G1 SCBA 2018 Edition states that activating EBSS in donor or receiver mode changes the SCBA use to Escape-Only, and the approved service time no longer applies.
Airline air and hose: the G1 SCBA 2025 Edition matrix requires respirable air meeting CGA G-7.1 Grade D or higher, and only the pressure ranges and hose lengths in the User’s Instructions.

ExtendAire II 2013 ed. vs 2018 ed.: which MSA part fits your G1?

Each edition has its own conversion kit and pouch. The 10156464 part page lists NFPA 1981-2013 and NIOSH, while MSA’s current bulletin calls the G1 ExtendAire II NFPA 1981-2018 edition compliant. MSA notes approvals may differ by configuration and part number, so check your SCBA’s approval label first.
