Embodiment Construction

[0077] I. Overview of the Z-filter media structure.

[0078] Fluted filter media can be used in a variety of ways to provide a fluid filtration structure. A well-known way is the z-filter structure. The term "z-filter structure", as used herein, means a filter structure in which individually corrugated, pleated or otherwise formed filter flutes are used to form longitudinal, usually parallel, inlet and outlet filter A set of flutes for fluid flow through the media; the fluid flows along the length of the flutes between opposite inlet and outlet flow ends (or flow faces) of the media. z-过滤介质的一些示例披露于以下文献中:美国专利5,820,646;5,772,883;5,902,364;5,792,247;5,895,574;6,210,469;6,190,432;6,350,296;6,179,890;6,235,195;Des.399,944;Des.428,128;Des.396,098;Des.398,046 ; and Des. 437,401; each of the above 15 cited documents is hereby incorporated herein.

[0079] A type of z-filter media in which two specific media components are bonded together to form the media structure. These two comp...

Abstract

An air cleaner and preferred components for an air cleaner are provided. In one arrangement, the air cleaner includes a band or cassette component, configured for removably receiving a z-filter media pack therein, during use. In another arrangement, the band is permanently mounted of the media pack. Air cleaner arrangements configured for use of the cassette or band therewith included an arrangement with a central housing section for receipt of the main filter cartridge and cassette, and which has thereon a mounting arrangement with 3 mountable sides. Preferred precleaner arrangements and outlet tube arrangements can be secured to the center housing section.

Description

[0001] This patent application claims U.S. Provisional Patent Application 60 / 649,301, filed February 1, 2005, and U.S. Provisional Patent Application 60 / 604,549, filed August 25, 2004, and filed April 30, 2004 Priority of U.S. Provisional Patent Application 60 / 567,121 dated . Application 60 / 649,301, Application 60 / 604,549, and Application 60 / 567,121 are each incorporated herein in their entirety in their entirety. technical field [0002] This application relates to air filters, for example, for cleaning engine combustion air of vehicles and other equipment. The present application provides preferred components, assemblies and methods. Background technique [0003] Particulate material is often entrained in the gas stream. In many cases, it is desirable to remove some or all of the particulate material from the gas stream. For example, airflow into the engine intake of a motor vehicle or power generating equipment often includes particulate material. Said granular materi...
