The Evaporative Air Cooler is a high-tech product. Its principle is as follows.
Water is sent to the water distributor by pump and sprinkle the surface of the cooling pad evenly,
and the water will flow directly into the side of air inlet of the cooling pad which is designed with special angle.
When the hot air passes the pad with water, it will lose considerable heat and get cool, also the air is filtered.
Then we can enjoy the cool, comfortable and fresh air.
The remained water will flow to drainage pan for the cycling.
