1. Overview of Air Suspension Centrifugal Blowers and Traditional Blowers

Blowers are commonly used for air supply in wastewater treatment, aquaculture, industrial production, pneumatic conveying, and other applications. As energy-saving and environmental protection requirements continue to increase, air suspension centrifugal blowers are becoming an upgrade option for some traditional blowers due to their high efficiency, low noise, and easy maintenance.

Traditional blowers mainly include Roots blowers and conventional centrifugal blowers. Air suspension centrifugal blowers, on the other hand, use air bearing technology to support the rotating shaft through an air film, reducing mechanical contact and friction during operation.

2. Main Differences Between Air Suspension Centrifugal Blowers and Traditional Blowers

2.1 Different Operating Principles

Traditional Roots blowers transport gas from the inlet to the outlet through the synchronized rotation of two rotors, while conventional centrifugal blowers use a high-speed impeller to generate centrifugal force and increase gas pressure.

Air suspension centrifugal blowers combine a high-speed motor with a centrifugal impeller and use air bearings to support the high-speed rotor. During operation, a stable air film forms between the bearing and rotating shaft, enabling an operating state with virtually no mechanical contact.

2.2 Different Energy Consumption Levels

Traditional blowers may experience mechanical friction, transmission losses, and other forms of energy loss during operation. When running continuously for long periods, their energy consumption can be relatively high. Air suspension centrifugal blowers use high-speed direct-drive motors and air bearing technology to reduce transmission and mechanical friction losses, providing better energy efficiency under suitable operating conditions.

For applications such as wastewater treatment that require continuous aeration, blowers often operate for long periods, making energy-saving performance an important factor affecting overall operating costs.

2.3 Differences in Noise and Vibration

Traditional blowers may generate mechanical noise and vibration from gear meshing, bearing operation, and mechanical transmission, particularly at high operating speeds.

Because air suspension centrifugal blowers use air bearings and high-speed direct-drive structures, they eliminate or reduce components such as gears and belts. As a result, operating noise and vibration are generally lower, making them suitable for locations with higher requirements for the working environment.

3. Application Advantages of Air Suspension Centrifugal Blowers

3.1 High Energy Efficiency

Air suspension centrifugal blowers use technologies such as high-speed permanent-magnet motors, variable-frequency control, and air bearings. Their operating conditions can be adjusted according to actual requirements. When the required airflow and pressure are achieved, these technologies can help reduce energy consumption during operation.

3.2 Reduced Maintenance Requirements

Traditional blowers generally require regular inspection and maintenance of lubricating oil, gears, belts, bearings, and other components. Air suspension centrifugal blowers reduce certain mechanical contact and transmission components and generally do not require conventional gearbox lubrication, resulting in fewer routine maintenance tasks and potentially lower maintenance workload.

3.3 Flexible Starting and Adjustment

Air suspension centrifugal blowers are typically equipped with intelligent control systems that can adjust airflow and pressure according to actual demand. For systems with significant load variations, proper control can reduce energy waste caused by prolonged full-load operation.

4. Will Traditional Blowers Be Completely Replaced?

4.1 Different Equipment Is Suitable for Different Operating Conditions

Although air suspension centrifugal blowers offer advantages such as energy efficiency and low noise, they cannot completely replace all traditional blowers. Equipment selection should still be based on factors such as actual airflow, pressure, operating hours, environmental conditions, and project budget.

Traditional Roots blowers offer mature designs, a relatively wide pressure range, and reliable operation. They remain suitable for certain applications involving higher pressure, lower airflow, or significant fluctuations in operating conditions.

4.2 Equipment Selection Should Be Based on Actual Requirements

For projects requiring long-term continuous operation, relatively large airflow, and high requirements for energy efficiency and noise control, air suspension centrifugal blowers may be an attractive option. For projects that prioritize pressure stability, mature equipment design, or initial investment costs, traditional blowers can still provide significant application value.

5. Conclusion

Overall, air suspension centrifugal blowers and traditional blowers differ significantly in operating principles, transmission methods, energy consumption, noise levels, and maintenance requirements. Air suspension centrifugal blowers offer advantages in energy efficiency, low noise, and reduced maintenance, while traditional blowers remain widely used in many industrial applications due to their mature design, reliability, and adaptability.

Therefore, equipment selection should not be based solely on blower type. Instead, the specific process requirements should be evaluated comprehensively to achieve an appropriate balance between air supply performance, operating efficiency, and economic benefits.
