Three-blade ceiling fan FR in black, both directions of rotation possible for summer and winter operation This fan, made of plastic, has a black surface and three blades. Overall, FR embodies a very modern, rather minimalist appearance and is also one of the very efficient ceiling fans. Moreover, it stands out for its particular smoothness and quiet operation, which make it a very comfortable air circulator. Functions There are six speeds to choose from, which can be selected via the remote control. However, FR can not only move in the forward direction, but can also be operated in the reverse direction. This serves to ensure that the ceiling fan also performs well in winter, because the warm air that physically collects at the top of the ceiling can be pushed back down into the room, so that the temperature is perceived as warmer with the same heating power. This definitely holds the option of saving energy costs in this way. The fan is not suitable for sloping ceilings.
