Vibration in Industrial Applications: Fans & Blowers

Friday, April 08, 2011

Air handling systems in industrial environments transfer large volumes of air to maintain adequate ventilation. These systems can range from small units with dimensions under a foot to extremely large units greater than 10 feet in height, depending on the specific application.

Before installation, each impeller undergoes a balancing process to minimize vibration when the unit is operational. Fans can often be balanced in a single plane, however blowers may have to be balanced at two planes if the have a large depth compared to the diameter. These costs add to the overall pricing for fan and blower products. Unfortunately, the initial balancing cannot overcome imbalances that occur after installation.  Read More
