In modern buildings, the kitchen or bath is often featured in the middle of the room, away from a window. Forced ventilation is therefore required to ensure adequate air flow.

This innovative product is the solution for humidors such as showers, bathrooms and sanitary facilities, to prevent mould formation on the walls and posible structural damage. The fan of previous ventilation concepts was either switched on or controlled by a timer. Without regulation, such a fan cannot work efficiently or be optimized so siut the application. After a while problems such as mould formation would occur, but can be prevented by using this humidity controller. The fan only operates if necessary and the device works automatically, needs no maintenance or additional operation.


Typical areas of application

  • Humidity regulation for poorly ventilated indoor bathrooms
  • WC`s, shower rooms and other sanitary facilities
  • Kitchens and kitchenettes
