Airline drainable blade louvers feature a specially constructed edge gutter and downspout in each blade. Falling water is drained to the jambs, removing cascading water droplets from the air stream. These features, coupled with the louver’s unique blade design, provide the industry’s top draining performance. Drainable blades are highly recommended for use in applications where water penetration and air performance are most critical. Airline drainable blade louvers allow very low water penetration with extremely high free area. These models have excellent rigidity, a feature that helps to minimize wind deflection.
