These are the existing drawing-based calculations for the selected country. Duct geometry is not a cutting template or an installation-clearance allowance. Select a size to check each model’s drawing before ordering.

CFM is calculated from geometric free area at an assumed 500 feet per minute. These figures are not measured airflow or pressure-drop results. Inserts, dampers and the installed system can change airflow. The 2-in-1 calculation uses the Drop-In drawing and does not establish performance with its metal insert fitted.

Size names are nominal labels. Compare your uncovered opening and the selected model’s drawing, including frame support and mounting requirements. For an exhaust cover, send the fan model and opening measurements to support.
