This is an air cooler. It has been used for only three years. It runs on water, meaning before running it, you need to pour a minimum of 10 to 15 liters of water inside, which results in cool air. It is completely imported from China. Brought in by hand. There is no risk of it getting damaged and it is extremely sturdy electronics. All machinery is okay, the switch is okay, and the fan is also okay, you can take it without hesitation. Thank you.
