Exchangeable filter unit for insertion into the housing of a filter system

摘要

A filter unit for exchangeable insertion in a housing of a filter system having a supporting component for supporting a filter unit in the housing; a multiplicity of individual, hollow filter elements wherein each filter element has an outer afflux surface for fluid to be filtered and an open surface portion for the outflow of filtered fluid from an interior of the filter element; and a casting resin. The hollow filter elements are united with the supporting component in such a manner that the filter elements are located substantially in their entirety on the second side of the supporting component. The filter elements are inherently stable filter elements composed with porously sintered together particles. The unification of the filter elements and the supporting component is effected by the casting resin covering the filter elements with a height of at least 1 cm. The casting resin slightly constricts the open surface portion of the filter elements and preferably constitutes the supporting component of the filter unit.
