MTA-FL-A Weatherproof Louver is designed with fixed horizontal blades arranged to overlap, providing effective rain protection while maintaining proper airflow. Its aerodynamic blade profile helps deflect water away from the air intake, making it ideal for external wall installation. Perfect for fresh air intake and exhaust applications, it ensures durability, efficiency, and weather resistance in various environments.
