PURPOSE: A vortex ventilation using a vortex is provided to rapidly discharge polluted air to outside by using a plurality of suction impellers formed inside a suction fan because the polluted air in a ventilation area is inhaled inside the suction fan by forming a vortex around a suction hole due to a plurality of vortex impellers in the lower part of a vortex fan. CONSTITUTION: A vortex ventilation using a vortex comprises a fixed bearing(21), a vortex fan(10), a suction fan(13), a rotary gear(17), a rotary bearing(22), and an exhaust pipe(15). The fixed bearing is fixed in the suction hole. A plurality of vortex impellers is formed in the vortex fan. The suction fan comprises a plurality of suction impellers. The rotary gear is joined to the exterior surface of the suction fan. The rotary bearing is joined to the upper part of the suction fan. The exhaust pipe is joined to the inner surface of the rotary bearing. A motor(18) is installed in a side of the rotary gear so the vortex fan rotates.
