What Are Exhaust Fan Louvers?

Exhaust fans' louvers are mechanical ventilation accessories typically installed on exterior walls where fans are mounted. They feature horizontal slats (blades) that automatically open when the fan is in use and close when it’s off. This helps maintain airflow control, energy efficiency, and indoor air quality while also protecting against external weather conditions and pests.
