Faber 6 Inch Make Up Air Kit

Make Up Air Kit Bring Fresh Air Back Into The Home and Improve Hood Performance With higher CFM range hoods more air is exhausted from today's tighter home with less "passive" air returning into the home through the walls. To "make up" for lost air and to prevent toxic air from coming in from garages etc., the Make Up Air Kit by Faber brings fresh outside air into the home through a separate fresh air duct with a sealed damper. This automatic motorized damper opens to bring in air when the hood is operating above 400 CFM and closes tightly when the hood is not in operation.
