Abstract

Air filter 1 for vehicles, comprising an external vessel 2 for housing a filter element 17, the vessel 2 having at least one air entry opening 6, downstream of which the first centrifuging elements 12 are arranged. Two other elements 8, 18 are arranged between this first element 12 and the filter element proper 17 and are intended to attenuate the sound waves propagating from the exit 27 towards the entry of the filter 1. <IMAGE>
