Choosing the correct aerodynamic equipment is critical to industrial operation efficiencies. Axial fans and centrifugal fans operate on two fundamentally different physical principles, making each suitable for specific industrial processes.
Axial fans force air to move parallel to the shaft around which the blades rotate. This design is highly efficient for transferring large volumes of air under low static pressure conditions. They are commonly employed in general ventilation, cooling towers, and radiator heat dissipation due to their high volumetric flow rate and straightforward space requirements.
Conversely, centrifugal fans pull air into the fan inlet and accelerate it radially through a 90-degree angle change, utilizing centrifugal force. This mechanism generates substantial static pressure, allowing them to push air through restrictive duct networks, industrial scrubbers, baghouse filters, and high-impedance material processing pipelines. Whether for clean air venting, heavy particulate transportation, or high-temperature gases, centrifugal blowers are the backbone of process manufacturing.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is a prestigious state-level machinery manufacture enterprise with over 50 years of blower design, manufacturing technology, and field application experience. We stand at the forefront of China's heavy machinery industry as the executive director unit of the China General Machinery Industry Association, the vice president unit of the Association's Fan Branch, and the executive director unit of the China International Turbomachinery Industry Alliance Council. Our reputation as the primary drafting unit of national standards for Roots Blowers solidifies our authority within the industry.
"In July 7th, 2011, the company was officially listed on the Shenzhen Stock Exchange (Stock Code: 002598), representing a monumental development milestone in our history of delivering reliable industrial ventilation products."
To serve international customers and meet localized application demands, we established two Sino-Japanese Joint-Ventures and one USA-based branch. This made us the first company in China's blower industry to establish an overseas operational branch. Our corporate network spans 20 holding companies with four specialized domestic manufacturing bases situated in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu). To maintain our technological edge, we drive continuous innovation through four independent R&D centers in Beijing, Shanghai, Wuxi, and Shijiazhuang.
Our primary industrial facility, inaugurated in 2005, is a high-standard modern industrial park spanning an impressive 430,000 square meters. In 2020, our parent company realized an operating income of 1.5 billion yuan and a profit of 150 million yuan (inclusive of participating holding companies), proving our financial reliability and robust operations to our worldwide partners.
Operating a modernized factory allows us to offer exceptional lead times, strict tolerances, and highly competitive cost-to-performance ratios. We maintain nearly 100 sets of advanced processing and inspection equipment, including CNC machining centers, five-axis machining centers, three-coordinate measuring instruments, and CNC machine tools imported from Japan and Germany. Additionally, ultrasonic flaw detectors protect structural integrity at every stage of the manufacturing process.
By implementing the world's most advanced product lifecycle management (PLM) system alongside computer-aided manufacturing (CAM), computer-aided process design (CAPP), and computer-aided testing (CAT) technologies, we successfully shorten design-to-delivery cycles while elevating dimensional accuracy to aerospace standards.
From municipal water works to high-demand chemical refining, our ventilation products are customized to match local operational demands.
Our high-efficiency Roots blowers and multi-stage centrifugal blowers provide continuous, low-maintenance oxygen aeration for activated sludge processes in industrial and municipal wastewater plants.
Designed for chemical, agricultural, and mineral processing facilities, our vacuum pumps and high-pressure roots blowers facilitate dense or dilute-phase pneumatic conveying of bulk materials across long distances.
We deliver comprehensive technical layout designs and industrial equipment packages for Mechanical Vapor Recompression (MVR) evaporation, crystallization, and energy-recovery concentration loops.
Our scientific research team comprises experts receiving State Council special allowances, municipal engineering specialists, and doctorate researchers introduced via the Jinan "5150" program. We host an official "Postgraduate Workstation" and employ over 10 domestic and foreign experts to lead academic advancements.
To keep our fluid mechanical designs ahead of market needs, we maintain active R&D partnerships with leading academic institutions, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University.
By leveraging proprietary technologies such as countercurrent cooling, fan noise reduction, anti-stick wear coatings, special seals, and twisted-leaf impellers, we hold 69 patents (including 5 invention patents) and 2 software copyrights.
At Shandong Zhangqiu Blower Co., Ltd., corporate culture is the foundation of our management. We recognize that industrial machinery is only as reliable as the people who design, build, and inspect it. Under the guiding principle of "Do it, and do the best," our work culture champions personal responsibility, innovative thinking, and continuous improvement.
Since 1997, our leadership team under Chairman Fang Rungang has pursued a clear growth strategy: "stretching the main business, embarking on new innovations, joint ventures and cooperation, and developing chapters."
