Abstract: A system for air destratification, circulation, and/or purification including an intake positioned proximate a ceiling of a space formed by a floor, a plurality of walls and the ceiling; an exhaust, positioned proximate the ceiling and separate from the intake; a fan structure comprising a motor mechanically coupled with fan blades; a first duct for coupling the intake to the fan structure; a second duct for coupling the exhaust to the fan structure; and at least one attachment for supporting the fan structure such that no additional stress is applied to the ceiling from the fan structure; wherein the fan structure moves air from the intake to the exhaust via the first and second ducts. The system may be capable of fitting within a single ceiling tile of a T-bar ceiling.
