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.
A filter apparatus comprising a filter element, a filter base, and a filter housing, including a first set of complimentary, keyed structures, for attaching the filter housing to the filter base.
A filter apparatus comprising a filter element, a filter base, and a filter housing, including a first set of complimentary, keyed structures, for attaching the filter housing to the filter element.
A filter apparatus comprising a filter element, a filter base and a valve, the valve restricting a flow of fluid into or out of the filter element when the valve is in a first position, and the valve allowing a flow of fluid into or out of the filter element when the valve is in a second position.
A filter element comprising inner and outer media packs, and an end cap, the inner and outer media packs being disposed one inside of the other, 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 filter apparatus comprising a filter element, a filter base, and a filter housing, the filter housing includes a flow tube, the flow tube is connected to the filter housing.
A filter apparatus comprising a filter element, a filter base, a filter housing, and a flow tube, the flow tube includes a first portion and a second portion.
A filter apparatus comprising a filter element and a filter base, one of the filter base and the filter element includes an identification reader, and one of the filter base and the filter element includes an identification tag.
A filter element comprising a media pack, a flow tube and an end cap, the flow tube is connected to the end cap, the media pack is positioned around the flow tube.
A filter apparatus comprising a filter base, a filter housing, and a locking mechanism, the locking mechanism limits the rotation between the housing and the base.
