description The invention discloses a low-noise fan box, and relates to the technical field of fan boxes. Comprising a box body, the fan is a low-noise centrifugal fan, the centrifugal fan is provided with an impeller and a power mechanism, the diameter of the impeller is 300-445 mm, an air inlet is formed in one side of the box body, a filtering device is arranged on the air inlet, an air outlet is formed in the other side, opposite to the air inlet, of the box body, the vertical height of the air outlet is not smaller than the diameter of the impeller, and a noise reduction layer is arranged on the box body. The fan is a low-noise centrifugal fan, noise generated during operation of the fan is low, the air outlet of the box body is optimally designed, the vertical height of the air outlet is not smaller than 0.9 time of the diameter of the impeller, air outlet is smoother, the air outlet speed and noise are effectively reduced, the gap between the impeller and the air inlet ring is smaller than 4 mm, vortex is reduced,
