Greenheck® ECD-401 Combination Louver/Damper Drainable Blade, 15 x 15 in, Heavy Gauge Extruded Aluminum, 4 in D

ECD-401 is a combination louver/damper designed to protect air intake and exhaust openings in building exterior walls that, at times, require tight air shut off. Design incorporates a drainable head member, drainable stationary blades and operable blades with exposed blade linkage. When the operable blades are open, airflow is permitted through the louver, when the blades are closed, a tight seal is created to prevent the passage of air.
