Panasonic Eco Solutions’ WhisperValue DC enables easy code compliance and longer service life. The advanced ECM motor with intelligent self-adjusting SmartFlow technology senses the amount of resistance in the duct run and automatically adjusts the fan speed to deliver optimal cfm output, even in the case of a complicated duct run. The built-in pick-a-flow speed selector provides the capability to customize the ventilation fan for a variety of applications and to meet required airflow (50-80-100 cfm) with the simple flip of a switch.
