| 摘要 |
The invention relates to a combination filter arrangement (1) having a hollow cylindrical filter element (2) for filtering a first fluid medium, having a temperature compensation medium separated by means of cylindrical separating wall (5), as a second fluid medium in an area between the separating wall (5) and an outer housing (9) of the combination filter arrangement (1). The first fluid medium is made of a urea-water mixture, or comprises a urea-water additive having a higher freezing temperature than the first and the second fluid medium, and at least the separating wall (5) has an elasticity such that the volume expansion by freezing the urea-water additive can be absorbed. |
