摘要： A filter material for an air filter may include a substrate layer on an inflow side and a fine-fibre layer on an outflow side relative to a flow direction. The filter material may include a connection region arranged between the substrate layer and the fine-fibre layer. The substrate layer, connection region and fine-fibre layer may include pores having an aggregate degressive pore size with respect to the flow direction. A combined thickness of the substrate layer, connection region and fine-fibre layer may be at least 0.35 mm. The substrate layer may include a cellulose material and have an impregnation of resin disposed along the inflow side. The resin may amount to approximately 22% by mass of the substrate layer.

摘要： A method for manufacturing a filter medium comprising at least two filter plies according to which at least a first filter ply has a plurality of thermoplastically deformable fibres, by means of which the at least two filter plies are joined to each other in some areas. The method comprises forming, by means of at least two rolls of a pressing tool, at least one additional joining region configured in a web-like manner in the at least two filter plies in which the at least two filter plies are joined to each other.

摘要： A filter element for a filter device may include a filter body having at least one filter material for filtering a fluid. The filter body may have a first side and a second side facing away from the first side. The filter body may include a plurality of body pores. The filter body may have a porosity that is lower on the first side than on the second side. A nano-fiber layer may be disposed at least partially on the first side.
