The ELM90HFA offers a full 90-deg blade opening to achieve the highest free area, 74% in the industry. Blade and jamb seal options provide tight blade to blade and blade to frame closure allowing less than 4 cfm per sq ft at ½ in. pressure differential. Low torque operation and a concealed blade linkage for protection from weather exposure all within a 6 in. frame reduces the required installation depth.
