    • Radial seal filter assemblies and filter cartridges are described. According to various embodiments, a filter includes a housing that extends along an axis between first and second axial ends. A primary filter element is disposed in the housing and axially extends between first and second axial ends that respectively are adjacent the first and second axial ends of the housing, the primary filter element has a hollow interior and a first axial length. A secondary filter element is disposed in the hollow interior of the primary filter element, the secondary filter element having a second axial length, the second axial length being longer than the first axial length of the primary filter element. The filter further includes an end cap disposed on the second axial end of the primary filter element.
    • 描述了径向密封过滤器组件和过滤器滤芯。 根据各种实施例,过滤器包括沿第一和第二轴向端之间的轴线延伸的壳体。 主过滤器元件设置在壳体中并在分别邻近壳体的第一和第二轴向端部的第一和第二轴向端部之间轴向延伸,主过滤器元件具有中空的内部和第一轴向长度。 次级过滤元件设置在初级过滤元件的中空内部,次级过滤器元件具有第二轴向长度,第二轴向长度比初级过滤器元件的第一轴向长度更长。 过滤器还包括设置在主过滤元件的第二轴向端上的端盖。
