DFL - Extruded Aluminum - 4" deep channel frame - Drainable Blades

The Model DFL is a heavy duty Extruded Aluminum Drainable Fixed Blade Louver. It is designed to protect the air intake or exhaust openings in the exterior walls of any building from rain and weather while still providing efficient airflow. The Drainable Blade design provides the BEST PROTECTION against water entering the opening by channeling water away from the blades and down the jambs. This eliminates water cascading from blade to blade. The Aluminum finish is ready for you to paint in the field or leave as mill finish.
