An air-bearing centrifugal blower is a type of equipment that features an air-floating bearing and a high-speed permanent-magnet motor. During operation, it virtually eliminates mechanical friction, resulting in high efficiency. Consequently, it also delivers excellent environmental performance. However, dust and high humidity can affect the equipment's operation. Now, let us introduce you to the key features of the air-bearing centrifugal blower.
An air-bearing centrifugal blower is a type of air-bearing, high-speed permanent-magnet motor that operates with virtually no mechanical friction. It boasts high efficiency and, consequently, excellent environmental performance. However, dust and high humidity can affect the equipment's operation. Now, let me introduce it to you. Air-suspended centrifugal fan The characteristics.
Air-suspended centrifugal fan Featuring air bearings, direct-drive technology, an impeller, and a permanent-magnet brushless DC motor, this fan operates with zero additional friction. The fan automatically adjusts its power consumption based on the required output (airflow range: 40–100%), ensuring optimal operational efficiency of the air-bearing centrifugal fan. In fact, it integrates both local control and variable-frequency drive systems into one unit, eliminating the need for separate frequency converter cabinets and operator control panels. Through the fan’s built-in control panel, users can easily set various parameters—including fluid temperature, motor speed, outlet pressure, airflow rate, and power consumption—and access real-time data. High-efficiency filters, cooling systems, automatic anti-surge systems, as well as power failure and fault protection systems are all centrally housed within the fan cabinet, providing operators with convenience and significantly reducing the likelihood of operational accidents. Moreover, this equipment is vibration-free and produces low noise levels. Thanks to its air-bearing and direct-drive technologies, the air-bearing centrifugal fan generates no vibrations, negating the need for soundproofing measures. It is lightweight, requires no special foundation, and is easy and flexible to install.
The air-bearing centrifugal fan employs air bearing technology, eliminating the need for a lubrication system. This makes it ideal for providing clean air in specialized industries such as electronics, pharmaceuticals, and food processing. The air bearings can withstand temperatures up to 600 degrees Celsius. All the drawbacks associated with oil-lubricated bearing systems have been successfully addressed. Consequently, no maintenance is required over the fan’s lifespan. Unlike conventional fans that rely on gearboxes and oil-lubricated bearings, this fan features a series of high-tech impellers and motors, operates without couplings, and connects directly via intelligent control systems. Key components are manufactured using AL7075 (aircraft-grade aluminum) technology. These design features ensure that the air-bearing centrifugal fan is virtually maintenance-free, significantly reducing users’ maintenance costs and enhancing operational stability. Moreover, the device is easy to operate and control; its speed, pressure, temperature, and flow rate can be automatically monitored and adjusted via a personal computer. The fan operates under constant-pressure, load/no-load, and overload control modes, and can perform unattended operations thanks to surge protection. The fan regulates airflow by adjusting the rotational speed of the impeller. This speed adjustment allows for effortless adaptation of the airflow in response to changes in inlet temperature and pressure. Both automatic and manual adjustments of airflow are supported. The air-bearing centrifugal fan features a direct connection between the impeller and the motor—no gearbox for speed increase, no mechanical contact whatsoever, no lubrication system, and thus no wear or energy loss. As a result, maintenance costs are minimized, and the power transmission efficiency exceeds 95%.
By telling everyone Air-suspended centrifugal fan You should be aware of these advantages when you start using them in the future. If you’re not yet familiar with them, you’ll definitely want to read carefully. Alright, that’s all for today’s key points—hopefully, this has been helpful to everyone.
