The invention provides an axial flow type ventilator with four air-out station platforms, which is not connected with a pipeline, provides even flowing air, and comprises flow guiding bodies, an upper panel, long shutters and short shutters, a back guide vane, a stainless steel formed frame, an electric motor, an aluminum casting axial flow type impeller, a flow guiding plate, a lower panel and impeller barrels. The stainless steel profile frame is a cube welded by hollow stainless profile steel, the long shutters and the short shutters are welded on four surfaces of the stainless steel profile frame in the height direction, and the upper panel and the lower panel are welded on the upper surface and the lower surface of the stainless steel profile frame; the upper panel is connected with two flow guiding bodies by bolts; two impeller barrels are welded on the lower panel; two ends of the back guide vane are connected to the lower surface and the electric motor by bolts respectively; and the aluminum casting axial flow type impeller is arranged on a shaft head of the electric motor. The axial flow type ventilator with the four air-out station platforms has the advantages of stable and quiet running, large air amount, low energy consumption, and far flow path.
