Forwarding the good news: The Zhonghang Huaqiang air-bearing blower has received an authoritative recommendation from the China Association for Electronic Energy-Saving Technology!

Guizhou Zhonghang Huaqiang Technology Co., Ltd., established in 2009, is located in the Economic Development Zone of Guiyang City, Guizhou Province. Adhering to military-industrial technology, the company adopts a core business model of R&D based in Shanghai and manufacturing in Guiyang. It is dedicated to the production, manufacturing, and sales of air suspension main units and complete machines, as well as the production and sale of non-core military components and high-end precision parts. At its R&D center in Shanghai, the company boasts an R&D team comprising 10 doctors and masters, continuously driving technological innovation. At its manufacturing base in Guiyang, the company is equipped with 80 CNC machining centers of various types, including five-axis linkage machining centers, as well as a fully automated dynamic balancing testing machine made by Germany’s “Schenk.” Meanwhile, its quality inspection center is outfitted with advanced testing equipment such as three-coordinate measuring machines and image analyzers. Zhonghang Huaqiang will continue to expand its commitment to technological innovation, constantly enhancing product quality and technical standards, and contributing to China’s transition from “Made in China” to “Smart Manufacturing in China.”

The air-bearing centrifugal blower (single-stage high-speed centrifugal fan) is a blower of an entirely new concept. It leverages three core cutting-edge technologies—“ultra-high-speed direct-drive motor,” “air-bearing technology,” and “high-precision single-stage centrifugal impeller”—to usher in a new era of high-efficiency, high-performance, low-noise, and low-energy-consumption blowers. This next-generation, high-tech civilian product has been meticulously developed based on aerospace turbomachinery design expertise.

The air-bearing double-suction high-speed centrifugal blower is an efficient, energy-saving, and environmentally friendly product. It features a simple mechanical structure, few moving parts, robust control performance, and convenient maintenance. It employs automotive-grade, oil-free, highly reliable hydrodynamic air bearings that operate with zero friction and minimal mechanical losses. Leveraging advanced permanent-magnet synchronous motor technology, the blower can reach a maximum speed of 200,000 rpm and achieve full-speed operation in just 5 seconds. The motor efficiency is as high as 97%, meeting the stringent Tier 1 energy efficiency standards. The air-bearing double-suction high-speed centrifugal blower is equipped with a wide-range, highly efficient three-dimensional impeller that overcomes key technical challenges associated with low specific speed designs, ensuring exceptional efficiency. The integrated, specialized design of the main unit ensures noise levels below 80 decibels and vibration levels below 12 μm. With stepless speed regulation, the blower can be rapidly started and stopped, with a continuous start-stop cycle life exceeding 150,000 times.
