Evaporator Air Cooler is the new addition in home appliances category of Walton Brand. The Evaporative Air Coolers are built to maximize energy efficiency and keep costs low. Warm air is drawn into the cooler through a dust filter and enters the Honeycomb Cooling Media. Water pumped from the tank pours over the honeycomb media. As the warm air passes through the media, the water absorbs the heat, naturally cooling and humidifying the air, and propels the cooled air out into the room. This no-compressor system cools naturally, efficiently and inexpensively. Place the cooler in front of an open door or window. Ensure that there is adequate cross - ventilation in the room by leaving a door or window open opposite the cooler.
