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.
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.
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.
The highly efficient ceramic honeycomb heat exchanger provides the highest possible surface area for recovering heat from the outflowing air, achieving a heat recovery rate of up to 91%. At the same time, the elevated pores result in a comparatively low loss of pressure. The heat exchanger is made of a special ceramic material particularly resistant to chemical, thermal and mechanical influences.
The functionality of the outside cover has been designed right down to the very last detail. The noise deflector inside the cover minimises outside noise, as well as any airflow and motor noise. Due to the 3-degree gradient of the core-drilled hole, any condensate in the installation cylinder flows down to the outside cover, where a special lip lets it drip off. Even installation is simple, as it can be done completely without tools or having to drill holes. This also means that maintenance is simple.
The sensor is located within the fan unit, directly measuring inflowing and outflowing air. Registering the air’s temperature and humidity level, it automatically selects the level of ventilation in line with the selected mode. All SmartFan® systems allow a sensor to be retrofitted.
The new SmartFan® S is a further developed version of the existing SmartFan®. It combines all the features of the existing SmartFan with innovative sensor technology.
Its integrated sensors measure a room’s temperature and humidity level, enabling it to automatically select the right mode for achieving optimal ventilation. This in turn allows occupants to stop worrying about too high humidity levels or wasted heating energy. Thanks to the SmartFan S, they can always enjoy a comfortable climate in all rooms. The SmartFan® S is controlled via the modern TOUCH control unit, which also offers a wide range of modes in manual operation.
Anyone already using a SmartFan for his home ventilation and wanting to benefit from the advantages of the new sensor-driven controls can upgrade his existing system.
