The invention discloses an active noise reduction damping device for a magnetic suspension air blower. The active noise reduction damping device comprises an air blower body, a base, two vertical rackplates, a first spring and a second spring, wherein the lower surface of the air blower body is fixedly connected with the upper surface of a mounting plate; the base is arranged below the air blowerbody; a groove is formed in the base; the lower surface of a mounting plate penetrates through the upper surface of the base and is positioned in the groove; the two vertical rack plates are symmetrically arranged on the two sides of the middle of the lower surface of the mounting plate; the top ends of the two vertical rack plates are fixedly connected with the lower surface of the mounting plate; and one side of each of the vertical rack plates is meshed with a gear. Through cooperation of the first spring and the second spring, the active noise reduction damping device can buffer vibrationgenerated by the air blowe
