Fan Balancing Demonstrator


Fan Balancing Demonstrator, #202

This unique, versatile, precision, assembly allows for convenient demonstration and training in fan balancing and other vibration analysis-related topics.

Based on the design of a typical centrifugal fan, this heavy-duty aluminum device allows for assembly in a variety of configurations, creating a broad range of balancing scenarios.

Movable pillow block assemblies, provision for even or odd number blade configurations, and multiple weight locations, combine to create a challenging and realistic training tool.

Available from stock, this device can help make training in field balancing and basic vibration analysis more productive, challenging, realistic, and professional.
