The EcoJet Cyclone Reservoir Misting Fan cools a generous 800 square foot outdoor area circulating at an impressive 1,625 cubic feet per minute (CFM), reducing the area temperature by 10 - 20 degrees on average. Create an outdoor cool zone of comfort with cool mist that lowers the temperature, cleanses the air of odors, smoke and dust. The Cyclone EcoJet by Joape misting fans are quiet, low-maintenance and energy-efficient. With their unique center centrifugal disk design, there are no nozzles to clog or pumps to break unlike nozzle misting fans and systems. As water droplets hit the center disk spinning at super high velocity, they explode into microscopic fine particles that spread out into a cooling cloud of mist so fine you don't get wet! Reservoir models feature durable, weather resistant plastic casing with attractive design. These Portable Reservoir misting fans are on a rolling caster base with one locking wheel. The 18-gallon water tank provides cooling up to 15 hours, depending upon the misting level that can be set from low to high with an adjustable rear valve knob. Requires 110 volt outlet, uses light-bulb equivalent energy and low water consumption. The sanitizing UV light (available for the white misting fan) for inside the water tank, purifies the water and destroys microorganisms. Available in grey, black, or white.
