Faber CFMRED CFM Reducer Kit

For cold weather environments, tightly insulated homes or in high rise condominiums with ventilation restrictions, sometimes hoods under 300 CFM's are required by local building codes to prevent removing too much air from inside the home. The CFM reducer kit allows almost the entire collection of hoods to be converted to below 300 CFM. Ducting is reduced to 5" round when used.
