Abstract
A room ventilating device has an elongated duct mountable on or in the wall. The duct extends from near the ceiling to a blower mounted adjacent the floor. The blower draws hot air from along the ceiling down the duct. The blower is so formed and constructed as to project the hot air well into the room in a laminar flow thereby to induce a highly effective temperature equalizing air circulation in the room with the consumption of small amounts of energy.
