Zehnder Combiflow connecting element

Description

The Zehnder Combiflow enables the combustion air from the CH boiler to be combined with the ventilation extract air from the Zehnder ComfoAir Standard 300 Basic version. This makes it possible to use one collective outlet duct in the shaft for these two airflows. Part of the ventilation extract air is used to supply air to the CH unit. CombiFlow ensures a safe installation with one air intake duct and one flue duct. This facilitates a compact installation as less ductwork is required in the house/shaft.
