Broan CFM Reducer Kit 6 inch round

Specially designed airflow regulators limit high CFM range hoods to a maximum of less than 300 CFM, complying with most local codes for hood installations without the need for make-up air. As a result, these kits give access to a broader offering of styles and designs within the standard Broan line of range hoods without the need for costly add-on systems in the home.
