Explore our foundational range of heavy-duty centrifugal blowers, roots blowers, and specialized slurry pump systems designed for demanding industrial operations.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is a premium global manufacturer with over 50 years of blower design and manufacturing technology. With our continuous technological innovation, we have established two Sino-Japanese joint ventures and an overseas branch in the United States, pioneering global collaboration inside China's blower industry.
As the leading enterprise in the Zhangqiu industrial sector, we have secured the top position in China's domestic market for Roots Blowers. Our overall development strategy focuses on "developing our main business, pioneering new fields and innovating, and cooperating to build a great company." Powered by our commitment to "Do the best," we operate as a modern enterprise integrating design, production, and sales of Roots Blowers, Centrifugal Blowers, Industrial Fans, Slurry Pumps, Pneumatic Conveying Systems, Electrical Equipment, and MVR Evaporation systems.
In modern process industries, procuring a centrifugal blower fan is not simply about immediate purchase costs—it is about aerodynamic efficiency, duty cycles, and optimizing Total Cost of Ownership (TCO).
Mismatched pressure and flow values can cause compressor surge or stone walling conditions, which can lead to vibration and structural damage. Our engineering team uses advanced 3D aerodynamic software to model airflow, ensuring your centrifugal blower operates at peak efficiency.
Energy consumption accounts for over 80% of a blower's lifecycle cost. By utilizing Permanent Magnet Synchronous Motors (PMSM), variable frequency controls, and precision cast/welded impellers, we reduce daily power consumption, helping your facility achieve payback on capital investment.
For corrosive chemical applications, high-wear slurry environments, or high-temperature operations, our blowers feature specialized materials like cast iron, welded steel, and ceramic coatings to extend performance life in challenging conditions.
Industrial processing is shifting toward automation and energy conservation. We are focusing on developing high-efficiency centrifugal systems, smart blowers integrated with IoT diagnostics, and advanced magnetic levitation technologies. These designs help eliminate mechanical wear, oil contamination, and thermal losses, improving overall operation reliability.
Providing heavy-duty aeration, fluid handling, and gas compression systems across diverse industrial sectors.
Our provincial technology center supports the research, production, and sale of Roots Blowers, Roots Vacuum Pumps, Multi-Stage Centrifugal Blowers, Single-Stage High-Speed Centrifugal Blowers, Centrifugal Ventilators, and Slurry Pumps. We also provide desulfurization pumps, rotary feeders, splitter valves, and complete pneumatic conveying systems.
We supply turnkey systems engineering, including MVR mechanical vapor recompression plants, industrial wastewater treatment facilities, and complete pneumatic conveying systems. These integrated solutions help clients reduce project complexity and ensure reliable start-up operations.
Biological wastewater processes require reliable aeration blowers to keep dissolved oxygen levels stable. Our blowers run continuously in large municipal and industrial treatment facilities to maintain biological activity.
In flotation and mineral processing applications, slurries can be abrasive and highly frothy. Our high-efficiency slurry pumps, including foam pumps and ceramic lined pumps, are engineered to handle dense mixtures, reduce maintenance downtime, and increase overall mineral extraction yields.
Operating four manufacturing bases in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, supported by dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Our production facilities feature advanced processing and testing equipment, including CNC machining centers, five-axis machining centers, three-axis measuring coordinate systems, and imported ultrasonic flaw detectors. We utilize integrated PLM (Product Lifecycle Management), CAM (Computer-Aided Manufacturing), CAPP (Computer-Aided Process Planning), and CAT testing systems to maintain high manufacturing precision and shorten development times.
We work in collaboration with research universities, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University, to keep our engineering processes aligned with modern technology.
Our engineering design holds 69 authorized patents (including 5 invention patents) and 2 software copyrights. We operate under third-party certified ISO9001, ISO14001, ISO50001, and ISO10012 management systems. Our product lines meet global regulatory standards, including CE certification, Mining Products Safety Marks, and energy efficiency ratings.
Our corporate culture drives our commitment to engineering quality and global partnership.
We believe that corporate culture supports the development of large scale enterprises. We value the input and development of our workforce, creating a collaborative environment centered on engineering excellence. Our work concept is simple: "Do the best" to deliver high performance systems, prompt engineering drawings, and reliable technical support.
Providing technical answers to common queries raised by mechanical engineers, procurement directors, and plant managers.
Multi-stage centrifugal blowers use series-mounted impellers on a shared shaft to progressively increase pressure, making them suitable for variable flow demands. Turbo blowers, particularly those featuring Air Foil or Magnetic Bearings, are single-stage, high-speed units optimized for constant, high-volume flow applications. Turbo blowers offer high energy efficiency but require steady operating parameters to avoid surging.
Our centrifugal impellers undergo double-sided dynamic balancing according to ISO G2.5 standards. This minimizes radial and axial vibration during operation, protecting the bearings from premature wear, reducing noise levels, and ensuring structural integrity during continuous high-speed runs.
Welded blowers allow for custom aerodynamic geometry and material selections (such as stainless steel or specialty alloys) to handle corrosive gases or high temperatures. Cast iron blowers are durable, cost-effective, and suitable for standard industrial air processes and pneumatic conveying applications.
Air foil bearing systems use the surrounding gas to create a fluid film, separating the rotating shaft from the bearing surface during operation. This non-contact design eliminates mechanical wear, grease lubrication requirements, and associated maintenance cycles, ensuring an oil-free air discharge.
To design your blower system, we require the inlet flow rate (or mass flow), design discharge pressure, ambient operating temperature, altitude, relative humidity, and the composition of the gas to be processed. This data ensures our engineering team selects the correct impeller profile and motor sizing.
Each unit undergoes factory testing according to ASME PTC 10 or ISO 5389 standards. We conduct mechanical run tests, vibration analysis, temperature checks, and aerodynamic performance verification to ensure the equipment meets design parameters before dispatch.
