The Silvento ec - quiet, efficient and chic

Thanks to the ec-technology the power consumption could be reduced considerably. The Silvento ec is quieter than its predecessors because it works much more efficiently and can be operated with lower volume flows.

The lowest ventilation level is 15 m³/h. learn more

For the control of the Silvento ec, two modules are selected:

Basic board: The Silvento ec has seven ventilation stages between 15 and 60 m³/h. They can also be combined with time lag, interval switching and switch-on delay.

Comfort board: The Comfort Board is equipped with a humidity and temperature sensor in addition to the capabilities of the basic board. A finer and more individual humidity control, which controls the fan even without permanent basic ventilation, has not been available up to now.

Both modules can be combined with plug-in expansion modules:

The motion detector module with a radar-based motion detector makes switches superfluous. All control techniques of the basic module are triggered via the motion detector. With the help of the optional wireless module the Silvento ec can be remotely controlled by radio from external controls, sensors or with wireless switches without the need for additional wiring.

Versatile - now also suitable for use in cellars

The Silvento ec can not only be used in exhaust air rooms such as bathrooms, toilets and utility rooms, it also ventilates cellar rooms cleanly and hygienically.

Cellar ventilation

The Silvento ec is the new, innovative solution for cellar ventilation from LUNOS. It ensures a clean and hygienic ventilation of the cellar area. Comfort and a pleasant room climate can thus be easily achieved. Commissioning is carried out in connection with the circuit board Type 5/EC-KE as well as the switch Type 5/W2 FK. The fan permanently records the air humidity and forms an average value which can be achieved by ventilation. A permanent voltage is required for this.


The new Silvento ec is of course 100 % compatible with all parts of LUNOS. This means that old devices can be quickly and easily replaced with new ones if desired.


Due to its extremely low energy consumption, the Silvento ec is so efficient that it does not fall into the classification for the energy label and therefore must not be labelled.
