Sunpentown SF-616 Evaporative Air Cooler with Rotating Louver

Designed with micro-computer control system, this evaporative air cooler can lower surrounding temperature and humidify the air through the principle of water evaporation. Provides versatile and economical way to cool and humidify your immediate surrounding. Feature 3-D Cooling Pad and rotating louver for added cooling and air distribution. The Cooler easily rolls from room to room and can also be used as a fan or humidifier if temperature is not an issue. The remote control allows you to easily change settings. The Air Cooler works by endothermic reaction (a reaction that consumes heat), which sucks air through it 3-D Cooling Pad (saturated with water). As the air flows through the pad, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy. The 3-Dimensional Cooling Pad is made of cellulose paper, impregnated with unique ingredients for high performance and structural strength. Treated with special stiffening and wetting agents for maximum water absorption and retention; and with Anti-Rot chemical for prevention of algae and bacteria growth. Due tot he 3-dimensional weaving structure, the cooling pad allows longer contact between air and water. Note: The unit works well in dry climates; not very effective in areas with high humidity as the unit utilizes water to cool.
