Inside cover
Perfected flat design
With its aerodynamically shaped air outlet and integrated guide vane (a feature of modern turbine technology), the high-tech covers guarantee optimal airflow. The innovative solution with its integrated fan turbine technology boosts the fan’s performance, providing maximum airflow yet using minimum energy – as confirmed by the aerodynamic tests conducted by the Düsseldorf University of Applied Science’s Department of Fluid Mechanics. Moreover, the cover’s rounded design blends in with the décor.
Fine dust & pollen filter
For maximum health in your home
The fine dust filter* (ISO 16890: ePM 2.5) ensures maximum health protection in the home. Coarse dust, pollen and even the smallest fine dust particles can easily be filtered out. The multi-membrane filter unit has the largest possible surface area due to its multiple folding, which binds floating particles. Despite the dense fibre network, the volume flow is largely maintained. Dust and dirt can easily be extracted.
* optionally available, replaces the standard 3G dust filter.
Fan unit
Aerodynamic and exceptionally quiet
The reversible axial fan with its protective grille is at the heart of the ventilation system. The electromagnetic motor with its vibration damper cuts out practically all mechanical noise, while at the same time ensuring high performance (up to 46 m³/h when operated in pairs). The aerodynamically shaped rotor blades transport air in a highly efficient and silent manner. The fan’s main feature is its constant performance in both directions.
