Future Trends in the Centrifugal Fan Industry
2021-11-12
1. A Leap Forward in Highly Efficient and Energy-Saving Technologies
• Magnetic levitation leads the energy efficiency revolution
The penetration rate of magnetic levitation centrifugal blowers is accelerating, with non-contact transmission technology combined with a three-dimensional impeller design delivering 30%-40% energy savings compared to conventional equipment. By 2030, the market share is expected to exceed 35%.
• Aerodynamic breakthrough in impellers
The asymmetric blade design (with a leading-edge radius larger than the trailing-edge radius) effectively suppresses flow separation, boosting aerodynamic efficiency by 12% to 15%, and has become a key focus in technological competition among industry leaders.
2. Intelligentization and IoT Integration
• Widespread adoption of predictive maintenance
Built-in vibration and temperature sensors, combined with AI algorithms, achieve a fault prediction accuracy of over 95%, reducing maintenance costs by 40%.
• Dynamic voltage regulation now standard
The combination of electronically commutated (EC) motors and variable-frequency control accounts for over 60%, enabling stepless speed adjustment from 20 Hz to 50 Hz and delivering a 35% energy savings in building ventilation applications.
3. Strong Impetus from Green Policies
• Upgraded Energy Efficiency Regulations
In 2025, the mandatory "Energy Efficiency Limit Values for Fire-Rescue Ventilation Equipment" require that the overall equipment efficiency meet or exceed 82%, accelerating the phase-out of low-efficiency products.
• Mandatory energy-efficient building requirements
Buildings with centralized air conditioning systems exceeding 20,000㎡ must be equipped with equipment monitoring systems, sharply boosting demand for smart centrifugal fans.
• Wind power industry chain surges
In Q1 2025, wind turbine tender volumes reached 36.1 GW (up 112% year-on-year), with demand for high-power centrifugal wind turbines exceeding expectations.
4. Materials and Manufacturing Innovation
| Innovation Direction | Technical Solution | Performance improvement |
| Lightweight structure | Carbon-fiber-ceramic composite rotor | Power density increased threefold, with a 40% penetration rate by 2030. |
| Modular Repair | Reversible air intake box design | Maintenance efficiency improved by 50% |
| Corrosion-resistant upgrade | 304 Stainless Steel Impeller + Nano Coating | Chemical process scenario lifespan extended by 2x, model 511 |
5. Evolution of Market Dynamics
• Enhanced Head Effect
Infineon continues to hold the No. 1 market share, with its technological barriers creating a strong competitive moat.
• Competition in the mid-to-low-end market
Against the backdrop of overcapacity (with 2024 sales down 1.8%), local brands like Xiangming and Dunli are seizing market share by leveraging their cost advantages.
• Steady global growth
The AC centrifugal fan market is expected to achieve a CAGR of 4.0% from 2025 to 2031, with the market size surpassing $307 million by 2031.
