DUCT ASSEMBLIES FOR AIR MANAGEMENT SYSTEMS AND METHODS OF MANUFACTURE

An ultraviolet light surface protection system for a duct (24) may comprise an interior surface (56) of the duct; a light source (52) operable to emit a germicidal ultraviolet light into a flow path of the duct (24) defined by the interior surface of the duct to sterilize an air to be provided to a conditioned area; and a coating disposed on the interior surface (56), the coating configured to be ultraviolet resistive, reflective, and anti-microbial.
