ABSTRACT OF THE DISCLOSURE An air circulator apparatus and method for movement of large amounts of air in a confined space, e.g. a room or industrial building, are disclosed. Movement of air overcomes stratification of warmer air near the ceiling of the confined space. The apparatus has a duct through which cool primary air is moved from the floor level to the upper warmer air mass near the top of the room in an air column which induces secondary air into the column so that the air density at the top of the column is substantially less than that at the bottom of the column. The duct contains air advancing means in the form of a motor driven fan having propeller blades and a baffle to advance the air from the lower level and may also include air channelling means disposed between the air advancing means and the outlet opening of the duct. The air is moved through the apparatus at a velocity of at least 800 feet per minute.
