Swirling local exhaust

A swirl-type local ventilator is provided to prevent noise and power consumption by inclining a blade attached to a swirler and to discharge an amount of contaminated air by enlarging a discharge area. A swirler(100) is installed in a suction port of a discharge pipe and rotates about a discharge pipe(10) by power supplied from a driver(50). The swirler includes a rotational plate(20) installed in the suction port of the discharge pipe and a plurality of blades(30) attached to the rotational plate radially outward. The rotational plate rotates by a bearing or an additional driving device installed at a front end of the suction port of the discharge pipe. The rotational plate has a cylindrical shape. The rotational plate has a hole corresponding to an internal diameter of the discharge pipe.
