An air purifier for industrial plants has an ultraviolet (UV) cleaner. The UV cleaner has a duct casing, multiple UV generators and an air pump. The duct casing has a cavity defined in the duct casing, an air inlet communicating with the cavity and an air outlet communicating with the cavity. The UV generators are mounted in the cavity in the duct casing and generate UV when in operation. The air pump is connected to the air outlet and generates an outward air suction force through the air outlet. The air purifier operates without any filtering elements and has an excellent filtering rate.
