K8504

Airolite louver type K8504 is a combination louver that incorporates drainable stationary and adjustable blades in a single frame. When open, gutters incorporated in the stationary blades and jamb frames provide excellent resistance to water penetration and high volume intake and exhaust ventilation. When closed, dual durometer vinyl blade-edge gaskets effectively minimize air leakage and water penetration.
