Description
This innovative product is a problem solution for humid rooms like 
showers, bathrooms and sanitary rooms, in order to avoid fungus 
growth on the walls and prevent damage to buildings.
In modern new type of buildings, the bathroom ( or even the “Kitchen”) 
is also placed in the centre of the house  and therefore is often without 
a window. Therefore, to ensure a minimum air flow level, normally a 
forced ventilation system is envisaged.
In previous ventilation concepts, the fan was either switched on 
through a switch or by an automatic timer. The first solution is not 
comfortable and it performs wrongly by all means. The second 
solution which is achieved by means of time control is functionally not 
sufficient. Without regulation, such a ventilation cannot operate in a 
power and demand optimised manner and results in problems like 
fungus growth after some time.
All these disadvantages are ruled out by using our fan control for 
humidity regulation. Then the fan runs only if it is necessary and 
switched off again after some time with unwanted climatic conditions, 
if after the change of air no more drying is observed
The device operates automatically, requires no maintenance or addi-
tional service and offers optimum protection from humidity and fungal 
damage together with energy cost savings.  The acquisition costs gets 
amortised within a short time.
