The Boneco F220 allows for adjustable height to fit your individual needs. The head of the fan can be rotated 270 degrees manually so it can be pointed virtually anywhere you’d like. The superior air circulation is achieved by 3 main points: the single arm design which allows for maximum air intake, the large fan blades draw big amounts of air through the fan, and the uniquely curved shape of the front grid boosts the fan\'s air speed. This all allows for a truly versatile fan. 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 to help with the desired temperature within your room. The height is adjustable by adding or removing the supportive poles. At a height of 49cm or 85cm tall, the F220 is perfect for single rooms or large open spaces and is also ideal to help pull fresh breeze through an open window. The set up is easy as there\'s a single security screw that is used to fix the fan blade which makes the fan safe in use and the maintenance very simple and easy.
