Are SCBA facepieces interchangeable between different air packs. say can i buy a scott face piece and use it on Drager system vice versa or does it have to be used on their specific air packs
Our dept. just got new SCBA's and each one we looked at was different.The HUD and voice amps were all wired and connected differently.Captain 4 is right too.BIG difference between different manufacturers 2nd stage regulators.
No manufacturer will certify their SCBA if parts from any other manufacturer are used.
Manufacturers intentionally make their mask connections physically incompatible with any other manufacturer's 2nd stage regulators to prevent the sort of thing your question asks.
