Panasonic fans use less energy to move larger volumes of air than other fans, and they run cooler so they last longer, providing efficient ventilation and healthy indoor air for many years. The built-in thermal-cutoff fuse practically eliminates chances of overheating which can result in motor failure, which means this may be the last vent fan you ever buy.

ENERGY STAR® certified for energy efficiency & savings

ENERGY STAR®-certified vent fans meet strict parameters set by the US Environmental Protection Agency. Panasonic ventilation fans are ENERGY STAR certified and provide greater efficiency and healthier indoor air quality with less noise. High performance motors and improved blade design deliver the superior performance and long-life operation you expect from a Panasonic ventilation fan.
