Damper apparatus includes a housing and dividers in the interior of the housing. One of the dividers forms a plenum and two openings leading from the plenum to an air flow outlet of the housing. Separate damper blades control air flow through the openings. A second divider divides the housing interior into separate passageways, one passageway in communication with one opening and the other passageway in communication with the other opening.
