SF(G) Series Duct-type Axial Flow Fan
The SF(G) series features low noise, high airflow, energy-efficient performance, and a well-designed, structurally sound construction. Its blades are engineered based on the three-dimensional flow theory, making it the ideal complementary equipment for applications in chemical plants, light industries, residential buildings, and upscale hotels. This series of fans is perfectly suited for heat protection, cooling, ventilation, and air exchange in industrial and mining facilities, workshops, warehouses, and other similar environments. Additionally, they can be used for general industrial duct pressurization, as well as for supplying or exhausting air and providing rooftop ventilation. Customized options include the SF-I fixed-position unit, the SF-II adjustable-position unit, and the SF-III mobile adjustable-position unit, tailored to meet specific operational needs.
