An air-bearing fan is a new type of blower that is highly efficient, energy-saving, and environmentally friendly. It features energy conservation, low noise, oil-free operation, reliable performance, simple operation and maintenance, and a nearly permanent service life. So, how does an air-bearing fan work?

So, how does an air-bearing blower work?
Principle of the Air-Suspension Fan: The pressure section of the air-suspension fan consists of an impeller and a spindle. Air flows axially along the curved surface of the impeller, accelerates, and then exits radially. After passing through a diffuser, the air expands according to changes in cross-sectional area, causing its velocity to decrease and its pressure to increase, thereby facilitating the process of air transport.
The air-bearing fan employs a high-speed permanent-magnet synchronous motor coupled directly to an advanced three-dimensional flow impeller, utilizing cutting-edge turbomachinery technology. The air-bearing fan features a high-speed permanent-magnet synchronous motor directly connected to a highly efficient three-dimensional flow impeller—resulting in contactless, friction-free operation that requires no lubrication, thereby completely eliminating transmission losses. The three-dimensional flow impeller is made of high-strength aluminum/titanium alloy and has undergone 100% X-ray inspection as well as a 115% overspeed test, ensuring highly efficient and reliable performance. The air-bearing fan supports intelligent variable-frequency control, enabling both local and remote operation. The entire unit adopts a skid-mounted design, featuring a compact layout and easy installation.
Air suspension fan Compared with conventional Roots blowers, it can save approximately 30–35% energy; compared with conventional multistage centrifugal blowers, it can save about 15–20% energy; and compared with conventional gear-driven single-stage high-speed turbine blowers, it can save around 10–15% energy. In the process of wastewater aeration treatment, the use of air-bearing centrifugal blowers offers significant practical value.
