A filter element for hydrocarbon emissions in, e. g. , marine diesel engine applications, comprises a wound mat received within a filter bag. An annular end cap is bonded to one end of the wound mat, and is sealed around its periphery to a bag ring at the open end of the bag. The bag ring is then received and retained in a seat ring in the housing. The exhaust gas stream from the engine is directed through an opening in the end cap and through the wound mat and bag for removal of hydrocarbons and contaminants.

A filter assembly wherein a housing seat () and a cartridge cap () are keyed to insure correct filter replacement procedures. The seat () can comprise a family of pedestals () and the end cap () can comprise a corresponding family of pedestal-insertion pockets (). The correct filter cartridge can be easily installed (e. g. , periodically replaced), by aligning the pockets () of the end cap () with the pedestals () in the housing seat (), and inserting the pedestals () into the pockets ().

A cooking oil filter element and method are characterized by a filter media having a needled nylon pre-filter media layer and a melt-blown nylon main filter layer. The filter media is pleated and configured in a cylindrical shape, and end caps are attached to the ends of the cylindrical filter media through use of an interlock structure that provides, in addition to an adhesive bond, a mechanical interlock between the end cap and the adhesive.

A filter cartridge for installation in a housing having a housing seat includes a filtration media compiled in a cylindrical pack having a radially outer face, a radially inner face defining a central cavity, a first axial end face, and a second axial end face. An end cap having an attachment portion is bonded and sealed to an axial end of the filtration media. A hub portion connects the attachment portion to a non-circular locking portion axially spaced from the attachment portion. The locking portion extends radially beyond the width of the hub portion and includes a sealing face having at least one annular sealing element for sealing against the housing seat.

A hollow, cylindrical, resin-bonded filter cartridge has an inner, depth-type filter media with a graded density which decreases (becomes porous) in the radial direction from the inner surface to the outer surface. An outer strip of filter media is then wound in a spiral or helix around the inner filter media. The outer filter media is also a depth type of filter media and has uniform density and is wound with adjacent windings abutting one another such that a continuous groove or channel is provided along the length of the cartridge. The groove or channel provides a greater effective surface area on the outer surface of the filter cartridge. The outer strip of filter media preferably comprises a lengthwise-extending body panel with a pair of leaves extending along either edge of the body panel. The leaves are folded against the lower surface of the outer filter media to provide a multi-layer outer filter media structure.
