Stainless steel centrifugal fans are ventilation equipment that uses stainless steel (mainstream grades such as 304 and 316L) as the core structural material (including key contact components such as the casing and impeller), and achieves gas transport through aerodynamic optimization design and precision manufacturing processes. Their core advantages stem from the inherent properties of stainless steel and targeted structural optimization. Compared to ordinary cast iron and carbon steel fans, they are irreplaceable in special working conditions such as corrosion, high temperatures, and high cleanliness, and are widely used in industrial and civil fields with stringent requirements for equipment stability, safety, and environmental adaptability.
