Air Flow Reducer, 8-Inch Round

These airflow regulators limit the CFM output of range hoods to comply with most local codes -- and 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.




  • Specially designed airflow regulator limits high CFM range hoods to a maximum of less than 300 CFM, opening up a wider selection of high performance hoods to homeowners
  • This kit is a 7" to 8" round and is designed to work with 8" dampers often used in newer homes
