This impeller is designed for 18-series units, providing a precise fit for the fan assembly. If your system's airflow is weak or the fan is vibrating excessively, a damaged impeller may be the cause. Replacing it can restore quiet and efficient operation. Whether you are performing routine maintenance or repairing a fault, this component is essential for keeping your boiler or burner system's indoor air circulation at its best.
