Filter Element or Adsorber Element with Enclosed Adsorption Particles and Method for Its Manufacture

摘要

A filter element has a filter medium that is made of at least two filter web layers and an adsorptive layer of adsorptive particles which adsorptive layer is substantially enclosed by the at least two filter web layers with the exception of lateral open edges. A sealing compound seals the lateral open edges at least during manufacture of the filter element. A frame part is attached by injection molding to the filter medium after sealing the open lateral edges with the sealing compound.
