An air flow control device is of the film obturator type, and is in the form of an independent module comprising a support frame on which two rollers are mounted for rotation. A film or blind, having open regions and closed regions for selectively controlling the flow of a stream of air, is wound on the rollers. The support frame comprises a guide frame which lies between the two rollers, for guiding the film and for contact with the film; and a press frame is arranged in facing relationship with the guide frame. The press frame carries springs for pressing the film against the guide frame.
