Abstract
Eine Luftstromfördervorrichtung (1) weist einen Luftströmungskanal (12, 13), einen Ventilator (2) mit einem im Luftströmungskanal (12, 13) angeordneten Lüfterrad (3) und einem Lüftermotor (5) zum Antreiben des Lüfterrades und wenigstens einen im Luftströmungskanal (12, 13) angeordneten Luftfilter (9) auf. Eine Steuervorrichtung (6) erfasst wenigstens einen Betriebsparameter des Lüftermotors (5) oder eine Veränderung dieses Betriebsparameters und erkennt eine Störung im Luftströmungskanal (12, 13), falls der erfasste Betriebsparameter oder die erfasste Veränderung des Betriebsparameters einen vorbestimmten Grenzwert überschreitet. An air flow conveying device (1) has an air flow channel (12, 13), a fan (2) with a fan wheel (3) arranged in the air flow channel (12, 13) and a fan motor (5) for driving the fan wheel and at least one in the air flow channel (12 , 13) arranged air filter (9). A control device (6) detects at least one operating parameter of the fan motor (5) or a change in this operating parameter and detects a fault in the air flow channel (12, 13), if the detected operating parameter or the detected change of the operating parameter exceeds a predetermined limit.
