1.Applications

　　Our cast iron single foot unit bearing motors are primarily used in commercial refrigeration, both evaporator fan and air cooler. However, they can be used in many applications demanding high efficiency and dependability with output ratings between 2-16 watts.

　　2.Design Concept

　　These motors will fit existing brackets used by GE, Morrill and A.O.Smith designed for quiet, efficient fan duty operation. The unit bearing motor significantly outperforms traditional shaded pole motor. With efficiencies three times higher than shaded pole motors, in addition to the reliable and quiet unit bearing design, our company provides users the most reliable and best energy savings solution for their applications.

　　3. Optimize your performance

　　To meet the requirements of clients, our unit bearing motors will match with a variety of mounting brackets and fan blades in order to optimize airflow and system efficiency.
