摘要： A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.

摘要： A filtration assembly includes a filter housing and a filter element. The filter housing includes a base and a cover including an underside having one or more retainer features. The cover is removably coupled to the base. The filter element is removably installed within the base when the cover is coupled to the base. The filter element includes filter media and an endplate coupled to one end of the filter media. The endplate includes an outer perimeter and one or more engagement features protruding from the outer perimeter. The one or more engagement features engage the one or more retainer features in the cover upon installation of the endplate into the cover, thereby coupling the endplate to the cover.

摘要： A water filter device for filtering water for supply, consists of an outer housing, a general water inlet through the housing, a mechanical filter within the housing, a carbon filter within the housing and a general water outlet through the housing, the filter device providing a flow path from the general water inlet, through the mechanical filter and the carbon filter to the general water outlet. The water filter device further includes a secondary water inlet through the housing between the mechanical filter and the carbon filter, to provide a second flow path from the secondary water inlet through the carbon filter to the general water outlet, the second flow path thus bypassing the mechanical filter.

摘要： A fluid filter device with a housing defining a cavity, the housing including a fluid inlet and a fluid outlet, a filter unit including a filter substrate and arranged within the cavity such that the filter unit and the housing define, within the cavity, a first chamber in fluid communication with the fluid inlet and a second chamber in fluid communication with the fluid outlet. The filter unit is movable relative to the housing between a first position and a second position such that in the first position, the first chamber is in fluid communication with the second chamber through the filter substrate, and in the second position, the inlet is in fluid communication with the outlet through a bypass line.

摘要： Oil filtration unit for removal of contaminants from oil including a housing with an inlet to receive contaminated oil from surroundings and release oil to an inner opening at a first pressure, an outlet adapted to release filtered oil to surroundings, and an oil filter for filtering oil in the inner opening of the housing. The oil filter includes an inlet with an outer surface, an inner volume to receive filtered oil at a second pressure lower than the first pressure, and an outlet inside the housing providing fluid/liquid communication between the inner volume and the housing outlet. The filter outlet includes a hydraulic resistance providing a fluid/liquid flow restriction between the inner volume and the housing outlet to increase the second pressure inside the inner filter volume and release the oil from the inner filter volume to the housing outlet at a third pressure lower than the second pressure.

摘要： A method of manufacturing a pump inlet housing and filter for a pump assembly, wherein the pump inlet housing and filter are monolithic, the method has the steps of: defining a pump inlet housing as a housing tubular shape with an inlet aperture boundary at a housing top end, and an outlet aperture boundary at a housing bottom end; defining a lattice filter between the inlet and outlet aperture boundaries; and performing an additive manufacturing (AM) process to additively manufacture the pump inlet housing and the lattice filter such that the lattice filter is integral with the pump inlet housing.
