What Causes Blower Impeller Noise and Vibration? The abnormal noise or vibration in a blower impeller is most commonly caused by physical imbalance (over 70% of field service cases), followed by bearing failure, loose mounting, or foreign object debris. If the impeller is not perfectly balanced, even a slight weight d...
