US 11,712,645 B2 · Filter interconnect utilizing correlated magnetic actuation for downstream system function

Abstract

A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.
