The structure of the evaporative air cooler is very simple. The water is delivered to the upper part of the wet curtain through the water pump in the water tank. The water uniformly moistens the contact surface of the whole wet curtain. When the hot air passes through the wet curtain, the water absorbs a large amount of heat in the air to cool the air passing through the wet curtain. At the same time, it is filtered to make the air cool, moist and fresh.
