摘要： A filter arrangement is provided. The filter arrangement generally includes an air filter (12) having an upstream surface (28) with a prefilter (4) positioned thereon. The prefilter preferably includes at least two layers of depth media (34, 35). In preferred systems, the prefilter includes two layers of depth media secured to one another by stitching (37, 40). In certain preferred arrangements disclosed, the prefilter includes an upstream layer of fibrous depth media (34) and a downstream layer of foam depth media (35), with two layers stitched to one another along peripheral edges. The invention also concerns provision of prefilters, and also air filter arrangements which include housings having air filters with prefilters according to the present invention operably positioned therein. Methods of construction and use are also provided.

摘要： An air cleaner (40) includes a housing (48) and an access cover. The internal volume of the housing (48) can be reached through an opening (70) in a side wall of the housing. A filter element (50) having fluted filter media is removable and replaceable from the air cleaner (40). The housing is constructed and arranged to cam the element (50) into sealing engagement with the housing (48). The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner. The housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.
摘要翻译：空气滤清器（40）包括壳体（48）和通路盖。壳体（48）的内部容积可通过壳体侧壁中的开口（70）到达。具有槽纹过滤介质的过滤元件（50）可从空气滤清器（40）中移除和更换。壳体被构造和布置成将元件（50）凸轮与壳体（48）密封接合。检修盖包括用于帮助支撑并确保过滤元件适当地安置在壳体内的结构。将过滤元件安装在空气净化器中的方法包括将过滤元件的一部分滑动到壳体中的滑动表面上。维修空气净化器的方法包括将过滤元件倾斜抵靠壳体中的倾斜表面以释放过滤元件和壳体之间的密封。过滤元件可以具有手柄以帮助维修空气净化器。壳体可以具有窗口，以允许目视检查壳体的内部部件并且可视地确定过滤元件是否安装在其中。

摘要： A restriction indicator (10) for an air cleaner of an internal combustion engine. A bellows-type diaphragm (40) is biased toward a retracted position by a first end of a compression spring (45). A calibration wheel (50) threadingly engaging the housing (12) supports a second end of the compression spring, such that the restriction indicator can be calibrated by rotation of the calibration wheel. An end of the compression spring is seated on a slanted seating surface (72) so that a plunger (63) is pushed off-center to engage a latch (62) and lock the restriction indicator.
