Severe duty aluminum louver
AFL-501 severe duty aluminum louver protects exterior wall penetrations on FEMA 361 or 320 compliant storm shelters or safe rooms.
Greenheck introduces model AFL-501, a 5.5-in. deep, severe duty aluminum louver that protects exterior wall penetrations on FEMA 361 or 320 compliant storm shelters or safe rooms. AFL-501 incorporates inverted V style blades that lend high free area resistance to water penetration and very low airflow resistance, while providing maximum protection against extremely high wind loads and wind-borne debris. AFL-501 can withstand wind loads up to +/- 300 PSF and passes the ICC 500 debris impact standard of a 15 lb. 2×4 traveling at 100 mph.
