A great alternative to air conditioning, evaporative cooler rentals and swamp cooler rentals can effectively drop the temperature of the air by as much as 20˚ by simple technology using water and electricity.

Unlike misting fan rentals, swamp cooler rentals or evaporative cooler rentals do not spray mist into the air and do not get people or objects wet, no matter how close you are to the units.

These units operate on 110/120V outlets.
