Abstract
A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base, and to automatically actuate a fluid valve as the filter element is rotated into place on the base. Tool-less replacement of the element is provided. An embodiment of the element may include inner and outer substantially tubular-shaped media packs disposed about an axis, with one end of each of the inner and outer media packs being attached to an end cap of the element in a manner defining a fluid flow space between the inner and outer media packs for receiving a flow of fluid directed in parallel through the inner and outer media packs. A housing of the filter apparatus may include a flow tube configured to fit into the space between the inner and outer media packs.
