The turbine has a tower wall (11), an inner space surrounded by the wall and an opening (24) i.e. person doorway, provided in the wall. Multiple air filters (22) are arranged at the opening, where the filters have air passage surfaces larger than a surface of the opening. Distance of the opening, in particular a lower edge of the opening is equal to 20 percentages of width of the opening by tower base flange (13, 23). An anteroom (20) and/or a chamber are arranged with the filters at the opening, where the anteroom or the chamber has a door (21). An independent claim is also included for an arrangement of an air filter at a wind turbine, which has a tower wall. |
