Tjernlund Products, Inc., has a brochure available about its AireShareTMline of Room-to-Room and Level-to-Level ventilators designed that make too hot or cool rooms more comfortable.
The ventilators provide users with an unobtrusive, cost-effective way to circulate heated or cooled air from fireplaces, stoves, electric baseboards, split system “ductless” A/C and window A/C units to uncomfortable rooms. The net result is extended comfortable living space from existing heating or cooling equipment.
