The quiet ABF-G5 Multi Speed Exhaust Fan with Humidity Sensor is an IC-rated bath fan suitable for new construction or remodel applications. Its contemporary square grille and range of designer finishes offer design versatility for a range of interior styles.

Airflow is achieved through an energy-efficient brushless DC motor. A high flow speed of 50, 80, or 110 CFM and a continuous lower speed can be set using switches in the fixture. The humidity sensor can activate high airflow when humidity rises above a level set by the user (50-100%), and run time can also be adjusted using the built-in timer.

The fan has rust-proof steel motor housing, a built-in backdraft damper and thermal shutoff. It fits in 2 x 8 inch construction, and includes articulating expandable anti-vibration brackets and a connector for 4, 5 or 6 inch ducts. ETL listed for use in a tub or shower enclosure when GFCI-protected.
