Fan Unbalance can be a result of increased dust/debris accumulation or buildup of material on the impeller during normal use. These problems may cause fans to become subject to increased fan vibration and imbalance especially if bearings, shafts or support structures are poorly designed or insufficient to handle the operating environment. If unchecked, this can lead to catastrophic fan failure and costly outages. Rotating machinery needs to run efficiently and without interruption. A variety of factors can throw a fan out of balance causing excessive wear and tear, shortening the life of equipment and lowering operating efficiency. Out of balance fans and shafts can even cause secondary damage to bearings and fan structures which could lead to extensive machine down time and interruptions to your production and operating schedules.
