Air vent for tall windscreen - with flat shape having a main central airstream and two lateral swirl streams

摘要

The air vent has a cylindrical connector for the ventilation duct and a flat outlet. It is formed from two identical halves each with special deflectors in one side, so that when the vent is put together the side streams are taken from diametrically opposite parts of the vent, leaving a central space for the main airstream. The connection to the air duct can be at an angle to improve the swirl effect set up by the lateral vents. The vent therefore has a long reach central vent for reaching up a tall windscreen in commercial vehicles, with swirling side vents which spread the airstream over a large area.
