The device is equipped with an active anion generator that you can turn on if desired. Press the ANION button, and the fan will immediately start producing negative ions, which are responsible for clean and fresh air. Safety is very important. If the protective grill is touched, the fan blades will stop immediately, and all indicators on the display will start to blink. After 5-10 seconds, when there is no longer any contact, the blades will begin to rotate again. The device features three speed settings and operates quietly at all levels. It comes with an infrared remote control and an additional foot switch for turning the fan on and off, as well as a clever touch-stop sensor. When the protective grill is touched, the rotor stops instantly. It has a built-in and switchable negative ion generator. Oscillation can be activated (up/down and/or left/right). Timer settings range from 0.5 to 7.5 hours. There are 3 speed levels (slow, medium, fast) and 3 operating modes (normal, nature, sleep). It also features a large, backlit LCD display and has a power output of 60 watts.
