The Boneco F230 fan is their most versatile fan. The head of the fan can be rotated 270 degrees so it can be pointed virtually anywhere you’d like. The superior air circulation is achieved by 3 main points: the single arm design allows for maximum air intake, the deep pitch fan blades draw large amounts of air through the fan, and the uniquely curved shape of the front grid boosts the fans airspeed. Point it at the ceiling for the signature air shower feeling and to reduce hot and cold zones, direct air between multiple floors, pull fresh air indoors, or use it with your air conditioner or furnace to achieve a uniform temperature within your space. The height is adjustable by adding or removing the connector poles. At a height of 19.3″, 33.5″ or 48″ tall, the F230 is perfect for single rooms, large open spaces, or rooms with high ceilings. Single security screw is used to fix the fan blade, this makes the fan safe in use and the maintenance very simple and easy.
