Cool large outdoor spaces where traditional air conditioners are impractical or impossible to use. Evaporative cooling technology offers an environmentally friendly way to lower temperatures up to 30°F in large areas at a fraction of the cost of normal air conditioners. This unit does not rely on any chemical or refrigerants – the process of evaporation naturally lowers air temperature, and this unit replicates that process on a greater scale by pumping warm air through a water-saturated medium and releasing cool air. Its maintenance-free Centrifugal Air Delivery System eliminates fan blades for improved performance and long-term reliability. Ultratough, one-piece molded plastic polyethylene housing offers corrosion-resistant, leakproof durability. 3/4" garden-hose connection for a constant water supply and easy refilling. Convenient water-level sight tube and sump drain. Adjustable louvers for directing cool air. Completely assembled and ready to operate right out of the box. UL-listed. Made in USA.
