Mountain Air Whisper EC Fans
The Mountain Air Whisper EC Fan has whisper-quiet operating volume.
Class-leading airflow and static pressure performance. Dual impeller mixed-flow technology with turbine-style inlet. A digital 3-mode Environmental Controller is included to provide the user with total control. One mode allows for manual control of the fan’s speed, while two thermostat-controlled modes either turn off the fan, or reduce its speed when the temperature of the room falls below set temperature.
