Dayton louvers are designed for protecting air intake and exhaust openings in exterior walls and in ventilation applications requiring protection from rain and weather infiltration. These stationary intake louvers feature a flattened aluminium bird screen to prevent the entry of birds at a ventilation opening and tabbed louver blades set at 45-degree angles, locked securely into the frame for a clean appearance and smooth finish. Raptor Supplies offers a wide range of Dayton louvers in fixed height and adjustable width designs for optimum building ventilation.
