Model AFL-501 is a 5.5-inch-deep, severe-duty aluminum louver that protects exterior wall penetrations on FEMA 361- or 320-compliant storm shelters or safe rooms. Model AFL-501’s design incorporates inverted V-style blades that lend high free area, excellent resistance to water penetration, and very low airflow resistance while providing maximum protection against extremely high wind loads and wind-borne debris. Licensed to bear the Air Movement and Control Association (AMCA) seal for water penetration and air performance, Model AFL-501’s UL-classified, windstorm-rated assembly can withstand wind loads up to 300 pounds per square foot and passes the ICC 500 debris impact standard of a 15 pound two-by-four traveling at 100 mph.
