Anhui Bengbu Electronic Information Industry Park Air Suspension Retrofit Project

In the core area of the Bengbu National Electronic Information Industry Base in Anhui Province, a modern precision manufacturing park is operating at full speed. Here, nanometer-level precision determines the international competitiveness of the products. The air cleanliness per cubic foot and the air supply stability per millisecond in the workshops directly affect the yield of chip packaging and high-end circuit board production. However, the core component powering the entire pneumatic system and clean environment — the traditional Roots blower — has increasingly become a hidden concern restricting the park's lean and green development. A power revolution aimed at addressing the dual challenges of “stable air supply” and “extreme energy efficiency” has thus quietly begun.

When Traditional Power Meets Precision Manufacturing

Bengbu Electronic Information Industry Park carries the mission of regional industrial upgrading. Its production workshops have extremely demanding requirements for the compressed air system. Processes such as pneumatic components, spraying equipment, and environmental positive pressure maintenance require minimal air pressure fluctuation (typically controlled within ±0.1%), as any pulsation or fluctuation could directly cause assembly deviations of precision electronic components or surface treatment defects. The potential oil contamination risk of traditional oil-lubricated blowers poses a threat to the clean workshop environment; the high temperature and excess heat generated during operation increase the load on the air conditioning system, affecting overall environmental temperature control precision.

At the same time, the intense noise and structural vibration generated by traditional blowers not only affect the employee working environment but may also create hidden interference with high-precision inspection instruments in the workshop. Therefore, the park's original power system could no longer match the future vision of “precision intelligent manufacturing” in the electronic information industry across the four dimensions of reliability, cleanliness, economy, and quietness.

The introduction of Krupp air suspension blowers

After rigorous technical selection and global research, the industrial park ultimately decided to introduce four Krupp high-power air suspension centrifugal blowers as the core equipment of its new air power center. This choice was based on the precise alignment between its technical characteristics and the park's needs.

1.Disruptive core technology

100% oil-free air foil bearings achieve non-contact, friction-free rotor operation, fundamentally eliminating the risk of oil contamination, with air supply quality reaching the highest Class 0 oil-free standard. High-speed permanent magnet synchronous motor and high-efficiency three-flow impeller, with direct drive structure eliminating gearbox losses, combined with an aerodynamically optimized integrated impeller, achieve ultra-high efficiency across a wide range of operating conditions. Fully intelligent variable frequency control system, with built-in advanced algorithms, responds in real time to pipeline network pressure changes, achieving millisecond-level precise linear regulation of supply pressure and flow.

2.Outstanding advantages directly addressing pain points

Non-contact operation and precise variable frequency control, with output air pressure fluctuation range far exceeding ±0.1%, provide a power source as stable as a “Swiss watch” for precision manufacturing, forming a solid foundation for improving product consistency. The fully oil-free design ensures absolute cleanliness of the air source and environment. At the same time, the blower itself generates extremely low heat, significantly reducing the cooling load on the workshop's air conditioning, providing indirect energy savings.

Compared to traditional Roots blowers, Krupp air suspension blowers have a more prominent efficiency advantage under partial load conditions. Their intelligent system can automatically adjust the operating combination and speed of units according to actual air demand, always maintaining operation within the high-efficiency range. Operating noise is below 75 decibels with minimal vibration, creating a quiet working environment for employees and eliminating concerns about vibration interference with precision instruments. No conventional mechanical wear parts, daily maintenance only requires replacement of air filters. Equipped with IoT interfaces, remote monitoring, fault prediction, and energy efficiency analysis are achievable, significantly reducing maintenance workload and costs.

Defining the "Power Standard" for a New Era of Precision Manufacturing

Since the commissioning of the four Krupp air suspension blowers with interlocking control system, their performance has exceeded expectations, delivering comprehensive value enhancement. According to relevant data calculations, under the condition of meeting the same process air volume, the average power saving rate of a single Krupp blower reached 31.8% compared to the original Roots blower. Maintenance costs were reduced by approximately 85%, saving substantial costs on lubricating oil, filter elements, spare parts, and labor hours. At the same time, ambient noise in the work area was reduced by an average of over 15 decibels, and the overall workshop temperature decreased in summer.

For electronic information manufacturing, stability and cleanliness are the lifelines, and energy saving is competitiveness. The successful practice of Bengbu Electronic Information Industry Park clearly demonstrates that in advanced manufacturing pursuing ultimate precision and efficiency, the power system has transformed from a behind-the-scenes auxiliary role to a front-line key player concerning core quality, cost, and environmental protection. With its outstanding features of oil-free cleanliness, extreme stability, high efficiency, energy savings, and intelligent controllability, the Krupp air suspension blower has redefined the standard of air power for the precision electronics industry. As China's manufacturing industry steadily advances toward high-end, intelligent, and green development, this power revolution that began with “breathing” will surely illuminate the path of transformation and upgrading for more industrial parks, driving intelligent manufacturing in China to proceed steadily and far on the journey of high-quality development.
