Plant Engineering | Understanding fan vibration and imbalance

Understanding fan vibration and imbalance Key concepts Detecting imbalance early reduces damage and lowers repair costs. Imbalance and vibration are not the same. Dirt, temperature, and loose fits can cause imbalance. Fans play a key role in most manufacturing processes by recirculating air, ventilating hazardous gases, and cooling machinery.
