Sound insulation

The FAV wall diffuser has been designed with outstanding sound insulation properties.


Storm protection

A storm protection feature limits supply air to 30 m³/h and avoids draughts.


Effective used air exhaust

Used air from kitchens, bathrooms, lumber rooms and toilet rooms is exhausted via an exhaust system. 


The FAV wall diffuser has been designed for discreet installation and outstanding sound insulation. It is commonly installed in facades as a wall diffuser for fresh air supply in family homes, office buildings, and multi-storey residential buildings. The wall diffuser is particularly suitable for installation in living rooms and bedrooms. The newly designed intake valve is suitable for both normal and high sound insulation requirements. All of the components required for installation are available as a complete package. 

Fresh air is filtered by the FAV and is distributed where it is required. Optimal efficiency can be achieved by choosing an installation position on the upper wall next to windows, with a height of 2.0 to 2.2 metres above a radiator. Storm protection limits supply air to 30 m³/h and reduce the potential for draughts.
