Product Advantages Product Features

The SF Series of axial-flow fans features smooth, streamlined surfaces, stable operation, high efficiency, low noise levels, and energy-saving performance.
Based on application requirements, the SF Series fans are classified into three types: duct-mounted, fixed-mount, and pedestal-mounted; they are further categorized into 12 distinct model sizes based on impeller diameter.
This product series is widely utilized in industrial and mining enterprises, as well as in civil buildings, for applications such as wall-mounted exhaust, localized air supply, and duct ventilation. They are also employed in the ventilation and air conditioning systems of various workplaces—including those in the chemical, light industry, food processing, pharmaceutical, metallurgy, power generation, and transportation sectors—as well as in warehousing facilities. (Operating temperature must not exceed 60°C.)
