Siboly hot air exhaust fan ventilate fan centrifugal exhaust fan

Through air exhausting by fan,producing negative pressure in the cooler,and at the same time water pump transports water to the water distributor,the surface of wet curtain is full of water.Moreover,for the special angle of wet curtain,water flows directly to the side of air inlet,absorbing a lot of quantity of heat in the air when the hot air is through the wet curtain full of water,reducing the air temperature through wet curtain,and filtering the air,making the wind blowing cool,humid and fresh.The water not evaporated falls back to the sole plate,forming water route cycle.

(1) How does an Evaporative Air Cooler work?

Evaporative Air Cooler cools the air by means of the evaporation of water. When water evaporates into the air, the result is a mixture of air and water molecules. This chemical change requires heat, thus energy or latent heat is taken from the air molecules - dropping the actual temperature of the air.

(2)How about the warranty of the air cooler?

1-2 year warranty for the whole machine. High-strength PP material, 10 years guarantee for the shell. 

(3)What are the differences between air coolers and air conditions?
