This is the indoor/outdoor evaporative air cooler that provides cooling comfort. It is engineered to flash evaporate water to provide portable cooling right where you need it. Independent laboratory tests revealed that this model produced the cooler air than pad-type models of similar size. The unit has patented nozzles that create tiny particles of moisture that flash-evaporate to provide efficient, effective cooling. Providing easy operation, the cooler has three speeds and the dual air ports swivel 180° and tilt up 15° for optimal cooling. The unit delivers a total of 570 cfm and produces cool air for up to six hours from just one gallon of water. Its integrated handle provides easy relocation and its 6'-long power cord plugs into AC. 29" H x 13" Diam. (13 1/2 lbs.)
