  • Filter element and support body for such a filter element
    Patent number: 9409104
    Abstract: A filter element for purifying a fluid at risk of freezing such as a urea-water solution for exhaust gas after treatment has an annular filter body and a support body surrounded by the filter body. The support body is made of an elastomer and is able to yield in a radial inward direction to compensate volume expansion when the fluid freezes.
