The Keystone line of evaporative air coolers offers an effective, low-cost cooling option in sizes to fit everyone’s
cooling needs. In areas with dry heat, such as the southwest region of the United States, the Keystone evaporative
air cooler line can be great supplement to your cooling system. The low power consumption will save you a
noteworthy amount on your energy bill in comparison to the cost of running a standard air conditioner. The
evaporative air cooler line comes in units suitable for indoor or outdoor use. For use indoors, the space requires
sufficient cross ventilation to function properly. With a number of fan speeds, the units evenly distribute cool air
after it is sifted through the filter, providing a fresh, clean breeze throughout your space. Equipped with castor
wheels, your evaporative air cooler can be easily transported to any room your guests choose to gather. For
those living in more humid climates, consider Keystone’s portable, through the wall, or window air conditioners.
