The quick couplings and plugs are divided into the short profile (ESI1A), designed for use on the belt and mask. The quick couplings feature a modified two-hand release mechanism, ensuring that accidental disconnection is not possible.
The ESI1A coupling can be connected to the ESI2A plug. However, the ESI1A plug can only be connected to the ESI1A coupling, and not to the ESI2A quick coupling.
These profiles are interchangeable with the standard profiles used by fire brigades, allowing direct connection to breathing air systems of other emergency services.
