Zusammenfassung:The device has a guide inlet opening that is configured on a suction side at an axial height in front of a flow inlet opening (15) of a bar structure and formed with opening surface smaller than flow inlet opening. The bar structure is formed by a grid structure consisting of intersecting grid bars with the grid openings enclosed by grid bars. The grid bars are provided such that the ratio of height to thickness of grid bars is greater than 5. The grid openings are provided such that the ratio of a peripheral grid width to radial width of openings lies in a range between 1/ 3-3.
