A flow restrictor reduces the airflow of a range hood by restricting the size of the opening through which air can flow. This reduces the amount of air that can be drawn into the hood, which in turn reduces the airflow. The flow restrictor in this case is designed to reduce the airflow of a Bertazzoni range hood's 600 CFM fan to 400 CFM.
