We present instruction which will help you in choosing appropriate fan for small wall or duct instalation :

 

1. Calculate the size of the room where the fan will be installed. Multiply all dimensions. The result of this calculation is a volume of the room: height x width x length = volume

 

e.g  Bathroom : 2,6m high x 3m width x 4m length = 31,2 m3

 

2. In table below you have few different types of a room and its proper air exchange multiple.

3. Calculate how many cubic meters of air should be processed by the fan in 1 hour – multiply multiple by volume – volume x multiple of an air exchange in 1 hour = exchange of a processed air in 1 hour.

 

e.g. 31,2 m3  x 5 = 156m3/h

 

4. In window product of every fan you can find characteristic.Choose fan with performance that matches your calculations.
