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.

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.
