Designed with blades that drain water down the jambs, these louvers keep water from running down the front of the blades, even in harsh weather. All louvers have a seal of air performance and water penetration from Air Movement and Control Association (AMCA), so they’ve passed rigorous testing to ensure minimal airflow resistance, while preventing light rainfall from entering your duct system.

Hurricane louvers meet AMCA 540 and 550, so they have passed tests for impact, rain, and wind common in a hurricane.

Water penetration rating is the air velocity at which water will start to pass through the louver. The higher the number, the better protected the louver is from rain.

Pressure drop is the amount of pressure lost as air passes through the louver into your system. The lower the pressure drop, the higher the airflow.

Airflow is the volume of air passing through the louver. Your louver should allow the necessary airflow required for your HVAC system.
