The BONECO F225 is height-adjustable to meet your individual needs. The fan unit can be rotated 270 degrees, allowing for flexible positioning. Excellent air circulation is achieved through three main elements: the single-arm design allows for maximum air intake, the deeply inclined fan blades draw large volumes of air through the fan, and the unique arc shape of the front grille increases airspeed. This creates a truly versatile fan. By directing the airflow upwards, you can create the typical air shower effect and reduce hot and cold zones; you can control airflow between multiple floors, draw fresh air indoors, or combine the unit with your air conditioning or heating system to achieve a uniform temperature in your rooms. The F225 also offers lower fan speeds when direct cooling is preferred. The height can be adjusted by adding or removing connectors. With heights of 49 or 85 centimeters, the F225 is ideal for individual rooms or large open spaces, or for bringing in a fresh breeze through an open window. The fan blade is secured with a single safety screw, ensuring safe operation and very easy maintenance. The upper part of the F225 contains the power controller with the aforementioned 32 speed settings: levels 1 to 16 are for direct cooling, and levels 17 to 32 are for indirect cooling. At the base, there is a display that shows the current fan speed. Additionally, when using the BONECO app, the timer function and display dimming levels can be adjusted according to the user's preference.
