1. A ventilation regulation system for conducting air being forced from an air supply area to a destination area, comprising:
a separating wall between said air supply area and said destination area;
a ventilation opening through said separating wall for allowing air flow through said separating wall;
an air regulation apparatus provided at least partly within said ventilation opening for regulating the air flow through the ventilation opening, said air regulation apparatus comprising:
a modular air regulation drum member that has a number of rotatable drum segments that can each rotate to adjustably block or deflect the air flow through said ventilation opening such that at least one among a direction, a speed and a debit rate of air is controlled through the ventilation opening;
a mechanical coupling mechanically linking said rotatable drum segments of said modular air regulation drum member into a coordinated rotational movement; and
an actuator acting on at least one, but not all, of said rotatable drum segments of said modular air regulation drum member to rotate said at least one of said rotatable drum segments, with the mechanical coupling allowing all of the rotatable drum segments to be rotated when said at least one rotatable drum segment is rotated.
