A filter element has a filter body of at least one layer of a flat web-shaped filter medium, separating a raw side from a clean side of the filter element. A hot melt system is provided and the filter body is glued together by the hot melt system. The hot melt system has a hot melt mixture that is made up of 15-85% by weight of a first hot melt that is polyester-based and 15-85% by weight of a second hot melt that is polyamide-based. The first hot melt and the second hot melt together amount to 100% by weight of the hot melt mixture. The hot melt mixture constitutes a proportion of more than 75% by weight of the hot melt system. The remainder of the hot melt system is made up of fillers, pigments, tackiness-imparting resins, and hot melts based on a polycondensate.

Filter element and method for producing a filter element

The invention relates to a hotmelt adhesive comprising a hotmelt adhesive mixture, the mixture including a) 15-85% by weight of a first, polyester-based hotmelt adhesive and b) 15-85% by weight of a second, polyamide-based hotmelt adhesive.

Filter element and process for producing a filter element

The invention relates to a hotmelt adhesive including a hotmelt adhesive mixture, the mixture having a 15-85% by weight of a first polyester-based hotmelt adhesive and a 15-85% by weight of a second, polyamide-based hotmelt adhesive.

A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support.
