The SVU400 central fan is designed for the continuous and quiet ventilation of rooms. It can be used in houses and flats, as well as in conference rooms, offices and public buildings.

The unit is equipped with an energy-saving motor, which enables operation at three performance levels. Its construction allows the connecting of up to seven inlet ducts with a diameter of Ø75 mm, and one Ø125 mm duct intended for connecting a extractor hood.

The CVU400 is comes with humidistat, which automatically adjusts the efficiency of the fan to the prevailing humidity. The simple device design allows for its quick installation and maintenance (cleaning) without using complicated tools.

The design of the CVU central fan allows it to be mounted on the wall or ceiling in both horizontal and vertical positions.


The humidity sensor has an operating range of 0% to 100%. The humidity level should be adjusted on the front part of the fan casing. The fan will start in trickle. When the humidity rises above the value set, the fan will automatically increase the speed to Boost (Full Speed). After the humidity drops below the set value, the fan will return to operation in trickle.
