Roof fans with IEC standard motor (DVNF)

From now on the new roof fans with IEC standard motor and integrated frequency converter (Type: DVNF) are available. 

The Rosenberg roof fans are used for ventilation of factories, swimming pools, kitchens, dining halls, warehouses, garages and so on. The fans are suitable for mounting on a flat or any shaped roof. The fans can be operated up to 120°C (80°C if speed controlled) as the motor is out of the air stream. The integrated control of the fan provides the right amount of air at the right time, just when it is needed. This works, for example, with additional control options via a continuously variable or multi-level potentiometer, with which the power can be adapted to the demand at any time. Due to the coordinated combination with motor and electronics, very low energy consumption is possible. The series is also available in sound-insulated version. More information about our roof fans you find here.
