This air cooler provides you with refreshment on hot days. Whether at home, in the office, or in the workshop, this practical device can be used almost anywhere. Thanks to the wheels, the air cooler is flexible in use and can be easily moved. The cooling can be adjusted in 3 levels, and the device can be controlled via a timer. How it works: Warm and dry air is drawn in from the front of the device and converted into cool, moist air. All you need to do is fill the reservoir tank with cold or preferably ice water.
