FRESH IN™ Series

Broan® FRESH IN™ Motorized Supply Damper

The Broan® Fresh In™ FIN-6MD is a smart, motorized supply damper that controls the fresh air entering the home's air handling unit. By continually monitoring the last 48 hours of outdoor temperature and humidity levels, the unit is able to estimate the best time of day to allow fresh air into the home. It’s the smart way to ensure ventilation, balanced with homeowner comfort. The FIN-6MD can be easily installed in the conventional inline configuration or be mounted directly to the AHU to save space and reduce installation time.
