Levian - ceiling fan with lighting for summer and winter operation This ceiling fan has rotating blades in beech and graphite, so that the appearance can be changed at any time and adapted to the interior ambience. Functions It can be operated in three speeds. The speed function can be controlled via the pull switch. In addition, a light source is integrated, so that you do not need two ceiling connections, but can conveniently combine both functions. On the housing there is a switch with which you can change the running direction of the fan, so that Levian is suitable either for summer operation or for use in winter. In the cold season, it then does not provide a cooling draught as in summer, but ensures that the warm air under the ceiling is pushed down into the room.
