I. Breakthroughs in Core Technologies
• Magnetic Levitation Centrifugal Fans Achieve a Leap in Energy Efficiency
Shandong Huadong Fan's magnetically levitated high-speed centrifugal blowers eliminate mechanical friction losses through non-contact transmission, and when paired with a three-dimensional impeller design, deliver a 30%-40% improvement in operational efficiency compared to conventional equipment. For instance, a 150-horsepower model can save over 200,000 kWh of electricity annually per unit.
• Multi-Blade Centrifugal Fan Impeller Patent
Guangdong Xinfeng Fan has obtained a new patent for its impeller, featuring an asymmetric blade design with a leading-edge radius larger than the trailing-edge radius. This innovative design effectively suppresses flow separation, enhancing aerodynamic performance and improving system stability.
• Modular Repair Technology Innovation
Zhejiang Juying Fan Co. has launched a centrifugal fan specifically designed for new-energy street sweepers, featuring an innovative, flipable air intake box structure that allows for maintenance and repairs without requiring complete disassembly—boosting maintenance efficiency by 50%.

II. Market Dynamics and Capacity Expansion
• Leading companies consolidate their market share
Infineon's ventilation fans have maintained the No. 1 market share in China's ventilation and air exchange fan sector for three consecutive years, and in 2025, the company was recognized as a "Shanghai Manufacturing Single Champion Enterprise," further solidifying its technological barriers.
• Differentiated Competition Amidst Overcapacity
Industry online data shows that in 2024, sales of centrifugal fans across the three major application areas—FFUs, EFUs, and AHUs—declined by 1.8% year-on-year. Meanwhile, domestic brands such as Xiangming and Dunli are accelerating their penetration into the mid-to-low-end market, thanks to their strong cost control and ability to adapt technologically.
• Global AC centrifugal fans experience steady growth.
According to QYResearch's forecast, the global AC centrifugal fan market is expected to grow at a compound annual growth rate of 4.0% from 2025 to 2031, surpassing $307 million by 2031. Key drivers behind this growth include increasing intelligence and lightweight design features.

III. Policies and the Green Transition
• The dual-carbon goals are driving demand for wind power infrastructure.
The National Development and Reform Commission's policies are once again driving a surge in wind power installations. In the first quarter of 2025, domestic wind turbine equipment bidding reached 36.1 GW—up 112% year-on-year—spurring the increased adoption of high-power centrifugal wind turbines in wind energy systems.
• Building Energy Efficiency Regulations Upgraded
The 2025 Kitchen & Bath China (KBC) exhibition is focusing on energy-efficient ventilation systems, with electronically commutated (EC) centrifugal fans emerging as a popular solution for green building certifications—thanks to their compatibility with smart control and dynamic pressure regulation features.

4. Industry Trend Outlook
Intelligent Integration: The IoT platform enables dynamic optimization of fan operating parameters, while boosting the response speed for remote fault diagnosis in maglev models by 80%.
Material lightweighting: Commercial adoption of carbon-fiber-ceramic composite rotor materials is accelerating, with penetration expected to exceed 40% by 2030. As a result, centrifugal fan power density is projected to triple.
In summary, the centrifugal fan industry in 2025 is poised for dual-driven growth—driven by technological breakthroughs that propel energy efficiency gains, and spurred by policy mandates pushing for a green transition. Leading companies continue to take the lead, leveraging innovative patents and strategic investments in intelligent technologies.
