    摘要: A filter material for a filter insert of a fuel filter for separating solid particles and water droplets from fuel. The filter material comprises a particle filter medium layer through which the fuel flows first during use and at least one coalescer medium layer which lies on the particle filter medium layer on the outflow side. At least one coalescer medium layer is gradient-free in the flow direction with respect to the geometrical structure and/or physical properties and/or chemical properties of the layers. The at least one coalescer medium layer has a thickness measured in the flow direction which is maximally as large as the thickness of the particle filter medium layer measured in the flow direction.
