SUNON EC Axial fan applied high efficient brushless DC motors and those products’ power consumption reduced almost 80% compared with our conventional AC Axial fans. Furthermore, it also pass dust-proof, water-proof IP68 rating. Importantly, SUNON EC fan also meet EU ATEX directive and protect most of flammable refrigerant (such as R600a, R290, R32, etc.) to make sure the safety of commercial refrigerator, freezer, icemaker, heat-pump water heater, heat-pump dryer and air-conditioning application.

EC (Electronic Commutation) = DC motor with Integrated AC to DC Converter. It combines AC and DC advantage which brings the best of both technologies.SUNON EC motor runs on a DC voltage, but with an AC supply. This design can not only achieve energy saving, but also it can control motor speed.
