Traditional fan air compressors rely on gear-based acceleration, with a structure comprising gears, bearings, and a lubrication system. As a result, they inevitably suffer from significant energy losses due to mechanical friction and issues such as noise pollution. So, let’s take a closer look at the core technologies behind air suspension fans!
With the application of three-dimensional flow technology in blowers, Air suspension fan Its development has gradually led to widespread application, while traditional Roots blowers and multistage centrifugal blowers—due to issues such as small capacity, low efficiency, high noise levels, and uneven air supply—are being phased out. Traditional fan air compressors rely on gear-based acceleration, with a structure comprising gears, bearings, and a lubrication system. As a result, they inevitably suffer from significant energy losses caused by mechanical friction and generate substantial noise pollution. So, let’s take a closer look at the core technologies behind air suspension fans!
So, what’s the difference between an air-flotation blower and a conventional root-type blower? Simply put, you pay more upfront but end up spending less in the long run. Although the equipment itself is more expensive, it consumes significantly less electricity during operation—saving over 30% compared to traditional blowers. It’s reported that in wastewater treatment systems, aeration blowers account for as much as 70% of total energy consumption. With the energy-saving advantages of flotation blowers, the savings become evident within just one year—enough to offset the cost of the blower in about a year. At the same time, these blowers eliminate the need for frequent oil changes, manual maintenance, and costly repairs due to breakdowns, thereby helping businesses save substantial expenses.
The air-bearing fan features an integrated design that combines a permanent-magnet high-speed inverter, a PLC control system, air-bearing bearings, and an intelligent control panel into a single unit. It is easy to install and even easier to operate, while also offering advantages such as advanced technology, stable performance, simple structure, convenient operation, and minimal need for manual intervention—all at reduced energy and routine maintenance costs.
Combining Germany's core technology with its own powerful R&D team, the air-bearing fan boasts five core technologies.
I. Ultra-High-Efficiency Permanent-Magnet High-Speed Motor Technology
The Explorer-Series permanent-magnet synchronous motors boast an efficiency exceeding 95%. Unlike other types of motors, they offer exceptionally effective cooling performance. Drawing on 15 years of experience in motor design, we have developed the world’s most efficient motors. The efficiency of our permanent-magnet motors reaches as high as 95%–96%! Based on calculations from real-world application cases, air-bearing blowers can save more than 30% energy compared to roots blowers! The investment cost can be recouped within just one year.
II. Air-Floating Bearing Technology
100% pure oil-free suspended bearing—no mechanical friction, with a virtually permanent service life. It produces no mechanical noise and no mechanical vibration, simply delivering air. Since 2000, it has been widely adopted in industrial machinery. With its simple structure, this bearing can operate stably at high temperatures, even surpassing oil-lubricated bearings. In permanent-magnet high-speed motors, it provides suspension capability without requiring complex sensor systems.
III. Aero-Turbo Technology
To facilitate in Air suspension fan In bearings operating at high speeds, the main duct series features impellers made from high-strength aerospace-grade magnesium-aluminum alloy. The design precision is as fine as 0.001 mm, ensuring optimal operational efficiency. The surface undergoes hard anodizing treatment, enabling the equipment to maintain high efficiency even under harsh environmental conditions. 4. World-unique motor cooling technology.
The Explorer-Series motors feature a two-stage cooling structure: internal air cooling within the motor itself, complemented by effective cooling via the motor’s air bearing assembly. Thanks to this robust two-stage cooling system, our motors do not require separate cooling equipment—such as externally connected forced-cooling fans.
V. Secondary Compression Technology
For pressures below 1.2 kg, first-stage air compression technology is used; for pressures between 1.2 and 4 kg, second-stage air suspension bearing compression technology is employed, both offering exceptionally high efficiency.
