Housing The fan casing is made of highly durable aluminium. The base plate is made of galvanized steel sheet. The integrated bird guard is made of powder coated galvanized steel. Impeller The dynamically balanced impeller is radial with backward curved blades made of composite material. Profiled, highly efficient blades thanks to the 3D geometry used. Motor The motor is asynchronous with squirrel cage and external rotor. The motor is equipped with integrated thermal contacts with manual restart. Speed control The fan can be controlled by means of a frequency converter with a sine filter, a star/delta switch or a five-stage transformer. Terminal block The fan has integrated thermal contacts, which must be connected to a corresponding protective relay in the motor terminal block (the protective relay is not delivered as an accessory). Noise level The sound pressure level is indicated at a distance of 4 m (free space). Installation The fan is started after connection to the ductwork for which it is intended, with the intake closed to avoid overloading the motor. After starting, the current is checked and must not exceed the nominal value (a higher value may indicate, for example, an unregulated ductwork). The direction of airflow is indicated by an arrow on the casing. The fan must be separately mounted and can be installed at a maximum deviation of 15° from the horizontal. - Additional Information
