The heart of the Middle Atlantic DUCT-COOL-2P system is a unique state-of-the-art fan that is both quiet and powerful. It has the ability to effectively pull heated air from up to 25 feet away, far from the user. Standard unit includes a built-in thermostat preset to turn on at 88°F and off at 85°F - so the system only runs when needed. Flexible system installs quickly, easily and can exhaust to any convenient remote location.
