1. A device for preparing an insulation product based on wool, comprising a chamber comprising an inlet opening through which a stream of carrier gas and a wool in the form of nodules or flakes are introduced, the gas stream being subjected to turbulent flow in said chamber, and an outlet opening through which flakes mixed with an outlet gas stream are expelled, and a deflection system configured to deflect the gas stream thereby enabling an increase in a residence time of the wool in the chamber, creating a disruption that aerates the wool in the form of nodules or flakes, said deflection means comprising at least one deflector element arranged in said chamber, the at least one deflector element extending from an interior wall of the chamber wherein said at least one deflector element comprises a deflection surface and at least one arm connecting said deflection surface to an interior wall of the chamber.
