Abstract (en)
[origin: WO2022238158A1] The invention relates to a filter element (10) for a filter system (100), said filter element comprising a hollow-cylindrical filter bellows (12) which has a substantially closed base (18) on one end face (16), at least one element-side resonator structure (20) being formed on the base (18) in order to attenuate the noise of a flowing fluid, the element-side resonator structure (20) having, on the outside of the base (18), at least two grooves (22, 24) separated from one another by a separating wall (26), at least one of the two element-side grooves (22, 24) being fluidically connected to the interior (30) of the filter element (10) via an opening (28), which element-side resonator structure (20), when installed as intended in a filter housing (110) of the filter system (100), seals tightly with a complementary housing-side resonator structure (120).
