Abstract

In a ventilation damper assembly in which a number of wing-shaped rectangular damper blades (7) are rotatably positioned with parallel axes of rotation between opposite frame members (1) in a rectangular damper frame, lateral tightening at the frame members is obtained without using particular tightening means, by forming each frame member (1) with a substantially convex cross-sectional shape with the minimum distance between the frame members aligned with the bearings (13) for the journals (12) of the damper blades (7), while each damper blade (7) comprises end portions (11) with a curved edge portion (11a) facing the frame members (1).
