    Abstract: A secondary filter element for a filter system for filtering a gaseous fluid, in particular for a self-cleaning intake air filter system of a motor, has a filter medium which in the intended operation is flowed through by the fluid from an intended inflow side to an intended outflow side. The secondary filter element has a support element covering the filter medium at the intended inflow side. A filter system with such a secondary filter element is provided.

    Abstract: A filter holder for a filter element that has an oval-shaped cross section transverse to a longitudinal direction thereof, the filter holder including: a receiving section configured to receive the filter element; fluid inlet for allowing fluid to be filtered into the filter holder; fluid outlet for letting the fluid filtered out of the filter holder; the fluid inlet is arranged so the inflow direction of the fluid to be filtered into the fluid inlet is parallel to the longitudinal direction of the filter element; the fluid inlet has a guide member configured to deflect the fluid as it flows into the fluid inlet such that it flows around in a spiral in the filter element that can be received in the receiving section in order to separate particles contained in the fluid to be filtered on a wall of the receiving section with the aid of centrifugal force.

    Abstract translation: 一种过滤器保持件，其过滤器元件具有横向于其纵向的椭圆形横截面，所述过滤器保持器包括：接收部，其构造成接收所述过滤元件; 用于允许流体过滤到过滤器保持器中的流体入口; 流体出口，用于使流体从过滤器保持器中滤出; 流体入口被布置成使得要被过滤到流体入口中的流体的流入方向平行于过滤元件的纵向方向; 流体入口具有引导构件，其构造成当流体流入流体入口时使流体偏转，使得流体以可以容纳在接收部分中的过滤元件中的螺旋流动，以便将包含在流体中的颗粒分离为 借助于离心力在接收部分的壁上过滤。
