【LIKE A COOL LAKE BREEZE - NOT A MIST FAN】Like a cool, lake breeze, Evaporative Air cooler reduces temperature through water evaporation. Moist, cool breeze can cool you down without spraying floor & furniture with water! 【INCREASE HUMIDITY IN DRY CLIMATES】The evaporative cooling fan is optimal when used in hot, dry climates to filter ambient air while increasing the condensation and delivering 2,600 CFM of cool airflow. Not effective in high humidity areas. 【ENERGY EFFICENT & ECO FRIENDLY】Evaporative cooling fans save up to 50% on electricity compared to refrigerated air conditioning systems. Using water instead of refrigerant prevents any release of ozone depleting chemicals into the air. 【DIGITAL DISPLAY AND REMOTE CONTROL】This cooling fan uses electronic control panel, aimed at ease of use and long term reliability, lets you select between 3 fan speeds and 1-12H timer settings, and there is also a full-function remote control. 【MANUAL & CONTINUOUS WATER FILL】WJD4500F-1Z has a 42L large capacity water tank. Utilize the Continuous Fill option by attaching a household hose with the included float adaptor, with low water shut off sensor. 【SUPERCHARGED, ECONOMICAL COOLING】3-sided (4-pieces) high-density cooling pads for increased evaporative surface area generating cooler air.Cooling, humidification and purification function, a multi-purpose machine.
