Filter element for a vapour extractor with edge suction and vapour extractor

摘要

The filter element (20) is provided with an active filter area (202), where a filter layer is also provided. The flow resistance of the filter element in the center of the active filter area is less than the flow resistance in the edge region of the active filter region. The flow resistance of the edge region of the active filter region decreases continuously or stepwise to the center of the active filter area. An independent claim is also included for an extractor fan.
