Abstract

The present application deals with a silencer (1) for compressed air systems, comprising: an inlet opening (3) for a compressed gas flow, a first sound damping means (4) being arranged downstream of the inlet opening (3); a second sound damping means (6) being arranged downstream of the first sound damping means (4); a grid (8) being arranged downstream of the second sound damping means (6), comprising at least two passages (9) through which the compressed air flow is adapted to leave the silencer (1), wherein the first sound damping means (4) has a smaller diameter compared to the second sound damping means (6), and wherein the second sound damping means (6) has at least a portion with higher density compared to the first sound damping means (4). Such improved silencer (1) is able to perform a noise dampening adapted to specific requirements (e.g. technical guidelines, standards), and hence to reach lower noise values compared to systems of prior art.
