PURPOSE: An industrial bladeless fan is provided to save energy without using an additional power source for driving a fan, and to simplify cleaning work for cleaning and removing foreign materials stuck on the fan. CONSTITUTION: An industrial bladeless fan comprises a base(10), a stand(12), a lever(28), and a head part. The lever is mounted on the stand to open and close a first passage, and controls the flow of compressive air moving along the first passage. The head part is a cylindrical shape of which both sides are open; is mounted on the stand; and comprises an inner plate, an outer plate, and a compressive air outlet. The inner and outer plates are arranged to form an annular second passage where the compressive air entered by the first passage passes. The compressive air outlet discharges forward the compressive air inside the second passage. |
