ENERGY STAR® rated WhisperGreen® ventilation fans from Panasonic feature a DC motor for ultimate energy efficiency.
The WhisperGreen LED with SmartFlow technology is designed to perform as rated and provide easier installation. When the fan faces static pressure, its speed is automatically increased to ensure optimal CFM output. The installer also no longer has to worry about compromising the fan's performance.
The WhisperGreen LED with SmartAction Motion Sensor also includes the SmartFlow technology but additionally has a built-in SmartAction motion sensor that automatically activates when someone enters the room.
