The WhisperCeiling DC and WhisperSense DC are precision spot ventilation fans. Each fan boasts Pick-A-Flow speed selector that offers the chance to meet required airflow CFMs.
The ventilation fans are suitable for new construction and remodeling projects. All models include an ECM motor with Smart Flow technology that senses static pressure and automatically increases fan speed. Integrated 4 or 6-inch dual duct adapters provide greater installation options.
The ENERGY STAR certified fans remove moist, polluted air from a home. The WhisperSense has a built-in dual sensor technology that provides an added layer of defense.
Both fans comply with ASHRAE 62.2, LEED, IAP, EarthCraft, California Title 24, and WA Ventilation Code.
