PURPOSE: A rainwater inflow preventing device for a turbo blower or a turbo compressor is provided to collect rainwater with a rainwater collecting unit of an air flow passage forming plate, to form a vortex with the collected rainwater, to make the rainwater flow to a vertical direction, and to discharge the rainwater to a gap between a backflow prevention horizontal members, thereby efficiently preventing the inflow of the rainwater. CONSTITUTION: A rainwater inflow preventing device for a turbo blower or a turbo compressor comprises a body unit, a plurality of air flow passage forming plates(80), a flow passage(S), and a discharge hole. The body unit includes an opening, and external air flows into the body unit through the opening as negative pressure is generated inside the body unit. The air flow passage forming plates are separately installed at a position, where the air flows by the negative pressure, inside the body unit. The air flow passage forming plate includes a guide unit, a connection unit, and a rainwater collecting unit. |
