The technological evolution direction of multi-stage centrifugal blowers has fully transitioned from traditional mechanical drive to high efficiency, contactless, intelligent, and system integration. The core breakthroughs are concentrated in four cutting-edge fields:
1、 Bearing Technology Revolution: Magnetic Suspension and Air Suspension Fully Replace Mechanical Bearings
Magnetic levitation bearings: achieve complete non-contact suspension of the spindle through electromagnetic force, completely eliminate mechanical friction and lubrication requirements, reduce vibration amplitude by more than 80%, and have a lifespan of over 100000 hours. They are suitable for high cleanliness scenarios such as food, medicine, and semiconductors.
Air suspension bearing: using the air film formed by high-speed rotation to support the rotor, the structure is simpler and the cost is lower, with a comprehensive efficiency of over 87%. It has become the mainstream choice for medium and large-scale industrial scenarios such as sewage treatment aeration, printing and dyeing, and papermaking.
Localization breakthrough: Shandong Yuqi Tongcheng, Aizhen Machinery and other enterprises have achieved large-scale production of magnetic levitation and air suspension fans. From 2025 to 2026, multiple domestic models can be seen on the AiGou platform, with prices 40-60% lower than imported brands, promoting the upgrading of environmental protection equipment in the southern Shandong region.

2、 Pneumatic design intelligence: AI driven optimization of ternary flow impeller enters the engineering implementation stage
AI+CFD collaborative design: The Xi'an Jiaotong University team took the lead in applying RandLA Net 3D point cloud recognition technology to optimize the full surface of centrifugal impellers, expanding the control parameters from traditional 40 to 114, achieving precise suppression of secondary flow and separation vortices in the channel, and improving efficiency by over 3%.
Upgrade of Three Element Flow Impeller: The North Glass Three Element Flow Fan adopts an automated simulation platform, which shortens the research and development cycle to 2 weeks. The efficiency of the new generation product has exceeded 92%, and it has been selected for the "Recommended Catalogue of Energy saving and Carbon Reduction Technology Equipment in the National Industrial and Information Technology Field (2025 Edition)".
Lightweight material application: High strength aluminum alloy and titanium alloy impellers are gradually replacing traditional cast iron, reducing weight by 10-15%, while improving fatigue resistance and adapting to high-speed (≥ 4000 rpm) operation requirements.
3、 Digitalization of operation and maintenance system: digital twin and predictive maintenance build a closed-loop management system for the entire lifecycle
Digital twin platform: Based on real-time sensor data (vibration, temperature, pressure, flow), a high fidelity virtual model is constructed to achieve 1:1 mapping of equipment operating status, supporting fault simulation and performance optimization.
AI predictive maintenance: By integrating mechanistic models and deep learning algorithms, the remaining life (RUL) prediction accuracy of key components such as bearings and impellers can reach over 90%. The warning lead time can be extended to 7-30 days, and unplanned downtime can be reduced by more than 50%.
Industrial Internet integration: equipment is connected to platforms such as Hailcaos and Roots Interconnection, supporting remote monitoring, energy consumption analysis, automatic start stop and multi machine coordinated scheduling, and realizing the "unattended+intelligent operation and maintenance" mode.
4、 Upgrading Energy Efficiency Standards and Green Collaboration: From Single Machine Energy Saving to System Carbon Footprint Optimization
Mandatory energy efficiency threshold: According to GB 19762-2023, the overall energy efficiency of newly produced equipment must not be lower than 82%, with a specific power of ≤ 4.8 kW/(m 3/min), forcing the industry to phase out 41.7% of low efficiency in-service equipment, with an annual energy saving potential of 4.83 billion kWh.
New energy coupling application:
As a supporting air compressor for green hydrogen electrolysis cells, it supports current densities of 2 A/cm 2 or higher, improving the overall efficiency of the hydrogen production system;
Coordinated operation with wind/photovoltaic power to achieve a zero carbon gas supply system of "wind and solar power+blower", applied in fields such as chemical engineering and energy storage (CAES).
Full lifecycle green design: Recyclable titanium substrate, oil-free operation, and low noise (≤ 75 dB) have become mandatory requirements of the new national standard, promoting the transformation of the industry from "manufacturing" to "green services".
