The device has a casing element (2) e.g. plastic fabric casing, reducing a sound level, and including outer and inner holes for delivery of a gaseous substance i.e. compressed air. A central alignment component (1) e.g. holding pile, is provided for the casing element. Link elements (3) spacingly align the casing element along the alignment component. The link elements are connected with each other in a chain shape. The link elements form a pull-harmonic stretchable guide for the casing element. A symmetrical cylinder ring is provided around the alignment component.
