Air Louvers 900FPL Door Louvers are designed for commercial hollow metal doors and commercial wood doors requiring exterior ventilation and weather resistance. Galvanneal steel construction provides corrosion resistance for exterior applications while the fixed Z-blade design allows consistent airflow without visibility through the opening. A factory-installed bird screen helps prevent debris and pest intrusion while maintaining ventilation performance. This model is suited for commercial, institutional, and industrial applications requiring durable exterior ventilation solutions.
