Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured to prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (30), and discharges the cooling water to outside after cooling a power source (10) includes: a filtration device (40, 40A, 40B) provided in the cooling water route to filtrate foreign matters remaining in the cooling water, and the filtration device is of a cartridge type that incorporates a filter (45, 72) for filtration disposed in a main water passage (P1) and a valve member (46, 66) configured to open and close a bypass water passage (P2) and that is configured such that in a case in which clogging occurs in the filter, the valve member opens to cause the cooling water to flow via the bypass water passage.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

A fluid-purifying element has a purifying medium delimiting an element interior. An end body is disposed at an axial end face of the purifying medium and has a radially outer circumferential side provided with an elastic annular seal element. The end body has an end body holding contour for the seal element that extends at least in sections continuously circumferentially at the radially outer circumferential side. The seal element has a seal holding contour arranged at a radially inner circumferential side thereof. The seal element has a seal surface extending at least across a portion of a radially outer circumferential side thereof. The end body holding contour has a protrusion extending at least part-circumferentially and radially outwardly. The protrusion tapers radially outwardly. The seal holding contour has a V-shaped depression extending at least part-circumferentially and radially outwardly. The end body holding contour engages the seal holding contour.

A water filter medium container includes a removable upper cover and a removable lower cover. The container includes a tube defining a filter medium compartment operative to receive a replaceable filter medium. A first containment element may be placed between the upper cover and the tube. A second containment element may be placed between the lower cover and the tube. The water filter medium container may be adapted to be placed in a water container.

A filter element including a filter media and methods for making the same are provided. The filter element includes a support core surrounded by a tubular ring of filter media. A first end of the tubular ring of filter media is coupled to a first end cap and a second end of the tubular ring of filter media coupled to a second end cap. The tubular ring of filter media includes a carrier media layer, a coarse filter media layer, a fine filtration media layer, a water-capturing media layer, and an outer wrap.

A container assembly is disclosed. The container assembly includes a container that contains a volume. Selected portions of the container assembly may be removable. A spigot assembly may be removed and associated with a filter assembly. An ambient light sensor may be included to determine when the filter assembly has been removed.

A water filter cartridge is provided. The water filter cartridge includes a filter housing enclosing a filtration material therein. The filtration material includes a first cavity generally surrounded by the filtration material and a second cavity formed between an interior of the housing and an exterior of the filtration material.

A Spin-on filter assembly that can be used with both suction-side and pressure-side filtration systems is described. The filter assembly screws onto a filter mounting head. The filter mounting head is part of a filtration system that provides fluid to be filtered to the filter assembly. The filter assembly filters the fluid to be filtered through a filter media contained within the filter assembly and provides the filtered fluid back to the filter mounting head. The filter assembly includes an upper seal that seals the clean side of the filter media from the dirty side of the filter media when the filter assembly is connected to the filter mounting head in an installed position. The upper seal includes a sealing ridge that has an elongated shape and is flexible such that the filter assembly can be used on both pressure-side and suction side applications in filtration systems.

A quick change oil filter includes a filter canister and filter base that may be installed and removed manually from an engine adapter on an internal combustion engine. The filter canister and filter base may hold at least about one third of the required engine oil supply when removed from the engine adapter. The engine adapter includes an oil inlet passage, an oil outlet passage, and a filter base mounting cavity. A check valve is biased to close an oil outlet opening from the filter canister, trapping oil inside the filter canister when it is removed from the engine adapter.
