Industrial fans, shown in Figure 2, have to be balanced due to imperfections during manufacturing; however the balancing process cannot compensate for mass imbalances that occur due to build-up of debris or erosion of the fan blades during operation. Improperly balanced, or damaged fans, and those with debris on the blades experience severe vibration issues which increase power consumption and noise emissions, and decrease product efficiency.
The XYO balancer can overcome deficiencies in the manufacturing process and compensate for imbalance changes while fans are operational.
The objective of the testing was to quantify the benefits of reduced vibration for fans operating with a prototype XYO balancer.
The testing was performed on three fans:
Vibration was measured with two velocity transducers mounted to the fan housing as shown in Figure 3.
Mass imbalances ranging from 0 to 21.65 grams were imposed at a radius of 100mm, giving a maximum imbalance of 2165g.mm. Six different mass imbalances were tested with and without the prototype XYO balancer: 0.00g, 7.25g, 9.25g, 11.25g, 16.45g and 21.65g.
Screws were placed at a radius of 100mm from the geometric center of the impeller to simulate the mass imbalance. The prototype XYO balancer was fitted to the unbalanced fan by removing the existing hub of the impeller (Figure 4). The fan assembly was supported on resilient mounts, secured in normal locations. The prototype XYO balancer was designed to compensate for a maximum of 2700g.mm of mass imbalance.
Note: the XYO balancer can be designed to compensate for larger mass imbalances if desired.
Vibration was reduced by 83% when the unbalanced fan was fitted with an XYO balancer. Even with the largest mass imbalance used for testing, vibration was reduced by 81%.
The XYO technology shows immense capabilities when applied to industrial fans. Performance values are based on a prototype XYO balancer and can be optimized further by working with a capable and innovative industrial fan manufacturer who seeks a strong competitive advantage in the market.

The XYO balancer showed significant improvements in vibration when applied to an unbalanced fan, up to 83%. Lower vibration levels can also provide other benefits for industrial fans, including:
