A filter assembly includes a housing defining unfiltered and filtered cavities, a coolant inlet, and a coolant outlet. The filter assembly further includes a stop valve movable between a stop valve closed position and a stop valve open position and an anti-drain valve movable between an anti-drain valve closed position and an anti-drain valve open position. The coolant inlet is in fluid communication with the unfiltered cavity when the stop valve body is in the stop valve open position. The coolant outlet is in fluid communication with the filtered cavity when the anti-drain valve body is in the anti-drain valve open position. A filter cartridge includes a bottom endplate having a rib with a rib end face engaging with the stop valve to move the stop valve body from the stop valve closed position to the stop valve open position when the filter cartridge is positioned within the housing.

A filtration system comprises a filter head assembly comprising an outlet slot, valve element, and latch element. The valve element is in fluid communication with the outlet slot and includes an open position and a closed position. In the open position fluid flow travels through the outlet slot. In the closed position fluid flow is prevented through the outlet slot. The latch element is configured to lock the valve element in the closed position. The filtration further comprises a filter cartridge structured to engage the filter head assembly. The filter cartridge comprises a first and second filter end. The filter cartridge comprises filter media and a keyed element disposed on the first filter end. The keyed element is structured for engagement of the latch element, wherein the engagement unlocks the valve element causing the valve element to be in the open position.

A filter assembly includes a housing having an outer cavity and an inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage. The gasket forms a first seal with a central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media configured to filter a fluid and an endcap including an annular tab portion that forms a second seal with the outer surface of the gasket when the filter element is positioned in an operating position within the housing. The vent passage circumvents the first seal and the second seal, allowing air to flow from the inner cavity of the housing to the opening in the central tube.

A filter media in which larger corrugations are impressed or embossed onto media that has been previously corrugated with standard corrugations. This construction greatly increases the beam strength of a resulting pleat that allows the channels to remain open during processing into the pleated media, and prevents buckling of the media duping gathering on current pleating equipment. In addition, once the media is pleated, the larger corrugations or embossments, combined with the standard corrugations, create large channels for fluid flow from pleat tip to the base of the pleat.
