Abstract

A filter device for gas filtration has a filter housing and a plate-type filter element disposed in the filter housing. The filter element is provided with a raw side and a clean side and is flowed through from the raw side to the clean side by a gas to be purified in a direction that is orthogonal to a filter plane of the plate-type filter element. A cover element is connected to the filter housing by a tensioning bolt penetrating the filter element. The filter element has a cutout forming a clean-side gas collecting chamber. A sealing element is arranged on the clean side of the filter element and frames the gas collecting chamber at least partially. A sealing eye is connected to the sealing element and arranged in the gas collecting chamber, wherein the tensioning bolt is guided through the sealing eye.
