Abstract (en)

[origin: WO2011123078A1] The invention is the air duct (10) having air duct end parts (11), which are left open, added to each other via using flanges (20), and used in ventilation, pneumatic carrying, filtration etc. systems found in industrial or commercial facilities, and it is characterized in that; said air duct end part (11) comprises an outwards inclined surface (12) with a certain alpha angle. The invention is bringing the level of the interior surface of the air duct body (10) and the level of the interior surface (21) of the flange at the same alignment via configuration of said outwards inclined surface (12) with the purpose of eliminating the protrusion and the resistance originating from the flange (20) formed at the interior surface of the air channels (10).
