Wow such a important site.
20. Diagnosing and Preventing Axial Fan Vibration and Noise (Beating)
Vibration and noise are common symptoms of operational issues in axial fans signaling reduced efficiency premature wear and potential structural failure[1][10].
Diagnosing the root cause is critical for maintenance and longevity. One of the most common causes of excessive vibration is a state of impeller unbalance where a buildup of dirt dust or material on the blades or minor physical damage to a blade tip shifts the impeller\‘s center of mass[1].

This mechanical imbalance leads to a dynamic force at high rotational speeds causing the fan casing and connected ductwork to shake[1]. Another significant noise phenomenon especially in installations with multiple parallel fans is Beating[1]. Beating is a distinctive throbbing noise that occurs when the sound waves from two or more fans operating at slightly different rotational speeds constructively and destructively interfere with each other[1].
