Stay cool and comfortable during hot days with the Ecotronic 1800 CFM Evaporative Air Cooler, a powerful and energy-efficient cooling solution designed for indoor and semi-outdoor spaces. This portable swamp cooler uses advanced evaporative cooling technology to deliver refreshing airflow while adding moisture to dry air, creating a more comfortable environment for your home, garage, patio, or workspace. With a powerful 1800 CFM airflow output, this evaporative air cooler helps circulate fresh, cool air throughout rooms up to 300 square feet. The 120° oscillation distributes airflow evenly across the space, helping to reduce heat buildup and maintain consistent cooling performance. The large 5.2-gallon water tank provides extended cooling for hours without frequent refilling. You can easily refill the tank from the top or connect a garden hose for continuous water supply, making it convenient for longer use. The built-in water level indicator allows you to monitor the remaining water at a glance. This 3-in-1 cooling system works as a fan, evaporative air cooler, and humidifier. Simply add water or the included ice packs to enhance the cooling effect during hot weather. With 3 adjustable fan speeds and 2 wind modes, you can customize airflow to match your comfort level. Designed for convenience and mobility, the cooler includes 4 smooth 360° caster wheels, allowing you to move it easily between rooms, garages, patios, or workshops. The remote control lets you adjust settings from across the room for added convenience. Whether you're cooling a bedroom, garage, patio, or workspace, the Ecotronic portable evaporative air cooler offers efficient cooling performance with easy operation and flexible mobility.
