Abstract: A fluid reservoir includes a reservoir body forming a reservoir volume and a header opening. A header seals the header opening and includes at least a heater disposed within the reservoir volume and a fluid draw conduit. A bag filter is connected to the header such that it completely encloses the heater and the fluid draw conduit such that, when fluid is drawn from the reservoir volume through the sump location, the fluid is filtered by the bag filter.

Abstract: A fluid reservoir for accommodating a fluid reductant used in an SCR exhaust treatment process may include various styles or designs of bag filters to filter debris and contaminants from the reductant prior to being channeled out of the reservoir. To secure the bag filter to a header assembly accommodating the various inlet and outlet tubes, in one aspect, the bag filter is adapted to fit around a header boss descending from the header assembly and protruding into the reservoir volume. Various configurations for the bag filter can be utilized to secure the bag filter to the header boss in a manner that isolates the tubes of the header assembly from the remainder of the reservoir volume to prevent debris and the like from being unintentionally drawn out of the reservoir.
