A supply air terminal designed for installation in an opening (3) in a wall (5) of a ventilation duct (7). The supply air terminal (1) extends in the duct (7) with a part (9) shaped to be able to take up part of the air flow transported in the duct and transport this for venting outside the ventilation duct (7), where the part (9) of the supply air terminal (1) has a considerable extend in the ventilation duct (7) in order to achieve a drop in pressure and a laminar flow in the supply air terminal (1).

1. A ventilation duct comprising: a wall defining a longitudinal duct through which air moves, said wall having an opening; and a supply air terminal in said opening, said supply air terminal having a slot therethrough that defines an air intake inside said duct and an air outlet outside said duct, said air intake being parallel to a longitudinal axis of said longitudinal duct, said supply air terminal having a lengthwise extension into said longitudinal duct that is 60-90% of an internal diameter of said longitudinal duct. 2. The ventilation duct of claim 1, wherein said supply air terminal has an air-flow-facing surface inside said longitudinal duct that has a length that is at least eight times a width thereof. 3. The ventilation duct of claim 1, wherein the lengthwise extension into said longitudinal duct is 75% of the internal diameter of said longitudinal duct. 4. The ventilation duct of claim 1, wherein said slot comprise plural separate openings that extend from said air inlet to said air outlet. 5. The ventilation duct of claim 1, wherein said supply air terminal has a width that is about 10% of the internal diameter of said longitudinal duct. 6. The ventilation duct of claim 1, wherein said supply air terminal has an air-flow-facing surface inside said longitudinal duct that has a surface area of about 8% of a cross sectional area of said longitudinal duct.
