Abstract: The disclosure relates to a gas permeable wall for preventing dirt present in a gas flow from passing through the gas permeable wall with the gas flow. In order to minimize maintenance, the gas permeable wall is a circumferential wall of a cover, and an outlet from the cover is provided for passing on gas having entered the cover through the circumferential gas permeable wall. A support is provided for attaching the cover rotatably to a device, and a drive unit is provided for rotating the cover.
