Abstract
Official abstract text for this publication.
A filter has first and second filter media ( 2, 3 ). The filter media define a flow space ( 4 ) between them receiving a device ( 5 ) for separation and flow guidance and dividing the flow space such that a functional space ( 25, 26 ) is disposed adjacent to the first or the second filter medium. The first filter medium ( 2 ) defines a hollow space ( 21 ) toward the outside, and the second filter medium ( 3 ) defines a hollow space ( 22 ) toward the inside. Each of the hollow spaces ( 21, 22 ) can be connected to at least one fluid duct ( 23, 24 ). The flow space ( 4 ) including the two functional spaces ( 25, 26 ) can be connected to at least one further fluid duct ( 27 ) that is separated in a fluid-tight manner from the other fluid ducts ( 23, 24 ).
