Abstract

Low-noise integrated air-filtering device, including a casing (2), which has an inlet pipe (3) and an outlet pipe (4), and a filter element (5), which is set inside said casing (2). The integrated device is further provided with a silencer device (7) including at least one resonator element (8) and one first damping element (10), which are set in series together and are contained inside said casing (2). Said resonator element (8) has a neck (12) having a length (L) that can be adjusted. <IMAGE>
