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 special arc shape of the front grille increases air speed. This creates a truly versatile fan. By directing the airflow upwards, you can create the typical air shower feeling while reducing hot and cold zones; you can control air between multiple floors, draw fresh air indoors, or combine the unit with your air conditioning or heating system to create a uniform temperature in your rooms. The F225 also offers lower fan speeds for when direct cooling is preferred. The height can be adjusted by adding or removing connectors. With a height of 49 or 85 centimeters, the F225 is ideal for single 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. The base features 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.
