Abstract: A scavenge tube is slidably attached to either a filter head housing or a liquid return port in a wall of a vessel. The scavenge tube can be slidably positioned to ensure that the tube is oriented within the area where the collected liquid will pool. In one example, the scavenge tube is slidably attached to the housing by way of being spring-biased. A slidable grounding tube is attached to an electrically grounded filter head housing and projects into a liquid collection region of a filter member and is in touching engagement with a metal portion of the filter member to ground the filter member to the filter head. In one example, the slidable grounding tube is spring-biased.

Abstract: A one aspect method of forming filter cartridge arrangements for use in air cleaners is provided. The method involves coiling a media pack with a central winding bead and cutting through the winding bead in the coiled media pack to form two media packs. An example filter arrangement is disclosed. In another aspect, a filter cartridge arrangement for use in air cleaners is provided. The filter cartridge arrangement includes a media pack including a plurality of inlet flutes and outlet flutes extending between first and second opposite flow faces and formed from an arrangement of facing sheet secured to corrugated sheet. An example cartridge includes a preform secured to the media pack. In some forms, the preform includes a grid arrangement extending across one of the flow faces. The grid arrangement can include a region of cured seal material positioned in contact with the first flow face, to secure the grid arrangement to the flow face.
