摘要： A damper for a heating, ventilation, and air conditioning (HVAC) system includes a damper blade, a frame coupled to the damper blade and defining a perimeter of an air flow path through the damper, and a frame member of the frame. The frame member defines a portion of the perimeter of the air flow path and includes a base portion, an upstream end portion, and a downstream end portion. Each of the upstream end portion and the downstream end portion extends obliquely from the base portion.
