Serenity® Duet Bath Fan Kit

Serenity® Duet Bath Fan Kit

Item Number: 47834

The Serenity® Duet Bath Fan is a stunning display of engineering and elegance. It is a quiet, energy efficient bathroom exhaust system that takes ventilation to the next level with its built in demand based control features and continuous local or whole building ventilation operating modes.


The bath fan is designed to automatically ventilate two bathroom locations matching your needs in creating a comfortable and accommodating environment. Exhaust grilles mount in the ceiling while the fan motor mounts in a remote location away from the living area. The result is a quiet yet powerful combination designed to help protect your home from the damaging effects of humidity. Serenity Duet is designed for intermittent or continuous operation to meet ASHRAE Standard 62.2.


Electronically Commutated (EC) exhaust fan, two ceiling grille with lights and grille housing with backdraft dampers. Two 10W dimmable LED bulb. Low voltage primary wall switch (Max, Auto, Off), low voltage secondary wall switch (Max, Auto), CAT5E cables. Uses a 6" flexible duct. UL listed for wet locations.


A built-in control board with multiple sensors provides error-free commissioning and simple operation. All operating features and modes can be easily configured to be enabled or disabled as desired

Humidity tracking

Humidity tracking is a demand feature that continuously monitors the %RH. Serenity® differentiates itself from other bath fan systems by knowing what the “normal” %RH is at any given time and for any given space. Proper ventilation is then enabled when abnormal humidity conditions are detected. Most other systems have a set %RH that would enable ventilation and then run for a preset period of time. Because Serenity® knows what normal humidity levels should be prior to detecting high humidity, ventilation will continue until humidity levels are back to within normal limits, protecting your property and ensuring comfort.

Occupancy monitoring

Presence detection is a demand feature included in the Serenity® Series that monitors occupancy of the space. After detecting continuous motion for 1 minute, ventilation will automatically be enabled. Ventilation will remain enabled for the duration the room is occupied and then run for a period of time (adjustable) before turning off.

Continuous ventilation

Continuous ventilation is an operating mode that can also be enabled. Minimum airflow is 20 CFM for local ventilation but is field adjustable to satisfy ASHRAE standard 62.2 for Whole Building Ventilation.


Serenity® is also available in a single grille (Serenity Solo) configuration suitable for residential low rise buildings.
