The Ventex 2430/2435 is a stationary 4 inch deep drainable blade, extruded aluminum louver. The 2430/2435 model's free area is one of the highest available for a 4 inch deep louver. The specially designed head and large drainage spouts in the jamb are highly effective at collecting water and dispersing it away from the louver face, thus eliminating potential water penetration. The 2430/2435 is ideal for intake applications in which the louver size is very restricted or applications which handle a large volume of air. Model 2430/2435 is AMCA certified for both water penetration and air performance.
