Pro 30

DUKA's pro 30 fan is of the highest quality with a very quiet motor designed for e.g. bathrooms. The fan is equipped with ball bearings, which ensures a long service life. Although it has a high performance, its power consumption is very low.

The fan can be either ceiling-mounted or wall-mounted.
For ceiling installation, the supplied clear foil damper must be removed from the fan's outlet spigot. This is important to prevent condensation from collecting on the back of the damper, which can then run into the fan motor and short-circuit it.
Leaving the damper off also provides better ventilation when the fan is not running, due to the natural buoyancy.

Without steering
This model is without control, here the fan starts when the light switch is activated.
