Publication number: 20060207948Abstract: A fluid filter assembly includes a housing, a service cover, a center tube removably secured to the service cover, a filter cartridge removably sealed and circumscribing the center tube, and a seal arrangement. The seal arrangement is between the center tube and portions of the housing to close a drainage channel to the flow of clean fluid flow therethrough, when the fluid filter assembly is operating to filter. During normal operation, the fluid filter assembly operates to allow fluid to flow into the housing through an inlet channel, through the filter cartridge, through openings in the center tube, and out of the housing through the outlet channel. Methods for servicing include removing a service cover from a housing to remove, together with the service cover, a center tube, and open a drainage flow passageway from the housing. Next a filter cartridge is removed from the center tube, and a new filter cartridge is operably mounted on the center tube.Type: ApplicationFiled: January 27, 2004Publication date: September 21, 2006Inventors: John Hacker, David Harder, Brent Gulsvig
