Airolite louver type K8204E is a drainable, adjustable blade louver with an electric motor actuator enclosed within the sill frame. When open, the drainable blades provide excellent resistance to water penetration and high volume intake and exhaust ventilation. When closed, dual durometer vinyl blade-edge gaskets and compressible stainless steel jamb seals effectively minimize air leakage and water penetration.
