Abstract

PURPOSE: A gas discharging fan is provided to mount a cap to a boss at a connection portion between an impeller and a shaft for preventing the corrosion of the connection portion, thereby improving the durability. CONSTITUTION: A gas discharging fan includes a shaft for rotating by the power of a motor, a boss(30) mounted to an end of the shaft, an impeller(20) connected to the boss, a casing, and a cap(40) mounted to a connection portion between the impeller and the boss for preventing the corrosion of the connection portion by waste gas. The cap is formed of FRP in molds and rounded in the center to be naturally protruded, thereby smoothly distributing the flow of a fluid.
