In 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 new CFM reducer kit from Faber allows almost the entire collection of hoods to be converted to below 300 CFM. This means even more designer hoods with higher CFM's are available in the Faber line, without the need to install costly make-up air systems. Homeowners with air restrictions are now only limited by their imaginations in choosing the right hood for the kitchen!
