Air filter having fluted filter media

摘要

An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. 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.

主权项

1. A side entry housing for an air cleaner comprising a body construction and a removable cover;
(a) the body construction includes an inlet construction forming an inlet end and an outlet construction forming an outlet end; the body construction provides a sealing surface against which a seal member of a filter element compresses to form a radially directed seal, and a stop surface that provides for the seal member to engage when a filter element is seated within the housing;
(i) the body construction includes a body member that includes a sidewall having a closed end and an open end and forms an internal volume, wherein the sidewall includes edges that define the open end, and wherein the open end is sufficiently large to accommodate accepting a filter element therethrough so that the open end corresponds to a side entry;(ii) the body member includes a slide mount that enables a filter element to be inserted through the opening and oriented with a seal member compressed against the sealing surface to form a radial seal;(iii) the slide mount includes a ramp having a slide surface angled downwardly from the open end to the closed end so that the slide surface is closer to the inlet end at the open end adjacent the edges than at the closed end; (b) the removable cover is removable from the body construction to expose the open end;
(i) the removable cover includes a portion extending toward the internal volume of the body construction when the removable cover closes the open end of the body construction; and(ii) the removable cover forms no part of the sealing surface.
