Hello there! We appreciate your inquiry at LinearSlotDiffusers.com. The dampers in our products are designed to restrict approximately 80% of the airflow. They don't close completely, as doing so would strain your AC unit and increase your power usage. For more information or further questions, feel free to contact us directly at (956)900-1103. Thank you!
