Ventilator system includes an external panel and interior baffle defining a plurality of vertically spaced air chambers vertically sealed from one another to prevent water droplets in any one of the air chambers from draining into the lower air chambers. Air passages in the baffle communicate with the respective air chambers at a higher elevation than air passages in the panel. The air stream entering the air chambers through the panel swirls and slows down prior to being discharged through the baffle. Also, side cavities communicate the ends of the air chambers with each other and with a catch basin below the air chambers. Within the air chambers are flap valves which close off the baffle air passages when the force of an air stream entering the air chambers through the panel exceeds a predetermined level to prevent water blow-through under high wind conditions. The baffle substantially fits inside the panel, thus eliminating the need for the builder having to rough out a stud opening in a building structure for receipt of the baffle. The total vent area may be increased for a given ventilator depth by providing some axial overlap between the panel and baffle to permit a corresponding increase in the width of the air passages therein. Also, the front face of the panel brick mold may be tapered axially outwardly for a portion of its width and/or the wall portions of the baffle which contain the baffle air passages may be tapered downwardly and rearwardly to permit the total vent area to be further increased for a given ventilator depth. At the back edge of the brick mold is a nailing flange which may be partially overlapped by a flange on the baffle.
