Model ESD-435 is an extruded aluminum stationary drainable louver that protects air intake and exhaust openings in exterior walls. The drainable head and stationary horizontal drainable blades collect and further channel water to the vertical downspouts located in the louver jambs where gravity takes effect, allowing water to escape at the louver sill.
