The direct drive heavy duty shutter exhaust fan employs motor to directly drive blades, by reducing intermediate transmission parts, effectively reducing the fan's running fault rate as well as use cost at later stages in life. The fan operates wtih low noise, large air volume, less power consumption and notable cooling effects. Through heavy duty swung drop hammer mechanism to realize automatic opening and closing of the shutter, it achieves the effects of dust proof, water proof and beautiful appearance. The direct drive heavy duty shutter exhaust fan is an ideal ventilation and cooling equipment for animal husbandry industry, greenhouse industry and industrial workshops.
