Air flow distribution elements (Opel Astra H)

Air is supplied to the car's interior through a network of ventilation ducts ending in nozzles equipped with fixed or rotating deflectors (see illustrations 15.1, 18.1, 18.2). Fixed deflectors for supplying air to blow on the windshield are located in the upper part of the instrument panel under the windshield, and the nozzles of the lower level air ducts are at the bottom of the panel, in the footwells.





Air is supplied to the vehicle interior in three main directions:

• On the driver's and front passenger's face and on the side windows (central, side and upper instrument panel deflectors);
• For windshield blowing (front instrument panel deflectors);
• Into the foot wells (lower air ducts).

The design of the louvered deflectors of the outlet nozzles of the front level air ducts allows you to control the intensity and direction of the outgoing flows (the rotating element is the deflector grilles). By turning the vertical regulator, you can change the intensity of the air flow, up to its complete cessation (position "O"). The direction of the air flow is changed by redirecting the grilles of the rotary deflectors (central and lateral) in the desired direction using the horizontal regulator.
