Abstract
A filter muffler includes a front element, a rear element, and a plurality of damping elements arranged between the front element and the rear element, where the damping elements are arranged radially around a central axis of the filter muffler such that a flow channel is formed between adjacent damping elements, where respective outflow-side ends of the damping elements have a diffuser element which has an outflow-side tapering, and where an angle α between two opposite sides of the diffuser element is selected from a range of 1°≤α≤8°.
