Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) represents over 50 years of heavy industrial machinery design, cutting-edge manufacture technology, and rich application experience. Established as a leading enterprise in the local Zhangqiu manufacturing sector, the market occupancy of our core product line—specifically Roots Blowers—has consistently ranked at the very top of China's blower industry.
We are a modern, publicly traded corporation (Stock Code: 002598 on the Shenzhen Stock Exchange since July 7th, 2011) that has successfully integrated system design, high-precision manufacturing, global sales, and extensive operational maintenance services. Our comprehensive portfolio encompasses Roots Blowers, AC Centrifugal Blowers, Industrial Fans, Water Ring Vacuum Pumps, Pneumatic Conveying Systems, Electrical Control Equipment, MVR Evaporative Concentration Systems, and advanced environmental Waste Water Treatment systems.
Guided by our overall developing strategy—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—and our working concept: "Do the best", we have established two Sino-Japanese Joint-ventures and a direct subsidiary in the United States, positioning us as a pioneer in the Chinese blower industry with active international footprints.
Modern industrial operations require aerodynamic design platforms that minimize turbulence and losses. Utilizing 3D CFD modeling, today's impellers feature backward-curved profiles that elevate polytropic efficiency up to 85%, significantly reducing carbon footprints and power costs.
The industry is rapidly shifting from conventional belt-driven AC induction motors to High-Speed Permanent Magnet Synchronous Motors (PMSM). By eliminating gearboxes and pulley systems, these direct-drive structures cut mechanical wear and minimize maintenance demands.
Industrial IoT (IIoT) modules are now standard on export-grade centrifugal blowers. Integrated temperature, vibration, and pressure sensors stream real-time operational data, triggering predictive maintenance alerts long before catastrophic failure occurs.
As a seasoned manufacturer, Shandong Zhangqiu Blower Co., Ltd. stays ahead of these trends. By investing in provincial-level technology research centers and partnering with renowned academic institutions like Tsinghua University and Xi'an Jiaotong University, we continue to engineer next-generation air-handling machinery that meets these evolving parameters.
Purchasing managers and industrial EPC engineers look for reliable, high-performing blower manufacturers who can provide long-term operational guarantees. The modern procurement checklist evaluates the following key dimensions:
Heavy industry demands uninterrupted duty (24/7/365). Procurement favors robust materials like premium cast iron or thick-welded carbon steel housings, combined with dynamically balanced impellers that prevent shaft vibration and bearing wear.
Stricter global noise regulations (OSHA, CE guidelines) require blowers to run with minimal noise. Incorporating advanced countercurrent cooling and acoustic silencers helps operators meet these strict workplace safety standards.
Off-the-shelf machinery rarely fits custom piping designs. Global buyers need engineering teams capable of delivering complete 3D CAD/CAM drawings within 24 hours to match exact footprint requirements.
In 2005, the company relocated to a newly built, high-standard modern industrial park. This facility covers an area of 430,000 square meters, featuring world-class offices and large-scale, climate-controlled manufacturing workshops that accommodate rapid development and strategic joint ventures. Over the years, our operational footprint has expanded across Wuxi, Dongguan, Chenzhou, and Jinchang, supported by dedicated research and development centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Our production floor features nearly 100 sets of imported precision machining equipment, including 5-axis CNC centers, high-accuracy coordinate measuring machines (CMM), ultrasonic flaw detectors, and advanced dynamic balancing stations imported from Japan and Germany. We utilize a Product Lifecycle Management (PLM) system alongside computer-aided process design (CAPP) and computer-aided manufacturing (CAM) to ensure tight tolerances and shorten production lead times.
We provide turn-key blower and pump systems optimized for critical infrastructure and demanding industrial applications:
Our multi-stage and Roots blowers supply continuous oxygen to biological tanks. In MVR (Mechanical Vapor Recompression) evaporator projects, our blowers compress secondary steam to reuse thermal energy, achieving energy-saving water purification and chemical concentration.
For chemical, agricultural, and mineral powder processing, our high-pressure Roots and centrifugal blowers provide steady air volume to transport raw materials via pipeline networks, minimizing product loss and contamination.
Handling harsh fluids requires wear-resistant components. Our slurry and desulfurization pumps, including ceramic variants, offer superior chemical and abrasion resistance in mining sumps and power plant scrubbers.
Our dedication to safety, environmental sustainability, and product performance is validated by our portfolio of 69 authorized patents (including 5 invention patents) and 2 copyrights, alongside certifications from global oversight institutions:
Our quality management systems meet ISO9001, ISO14001 (Environmental Management), ISO50001 (Energy Management), and ISO10012 (Measurement Management) standards. For European and mining markets, our blowers carry full CE Certification and the Safety Mark for Mining Products.
Operating in global heavy machinery industries requires rapid service delivery. Shandong Zhangqiu Blower Co., Ltd. established a dedicated direct branch in the United States and two joint-ventures with leading Japanese manufacturers to provide engineering and localized spare parts support across international markets.
Currently, our machinery operates in over 70 countries and regions—including the USA, Germany, Italy, and Brazil. Our localized export teams ensure compliance with local electrical requirements (such as 60Hz motor winding, NEMA/IEEE motor regulations, and UL certifications) and mechanical specifications, helping operators integrate our equipment into existing process plants without field modifications.
We continue to evolve our products to meet the industrial demands of tomorrow:
We are expanding our high-efficiency magnetic levitation turbo blower series. These oil-free systems eliminate mechanical friction, enabling lower maintenance costs and energy efficiency in aeration systems.
To support clean energy transitions, we are engineering specialized centrifugal gas blowers with advanced non-contact sealing rings and custom alloy impellers designed for handling hydrogen, acidic biogas, and toxic process gases safely.
We are integrating next-generation edge-computing IoT devices onto our blowers. These modules collect structural and thermo-dynamic statistics, communicating directly with DCS platforms via Modbus TCP or OPC UA protocols.
Our company culture serves as the foundation of our manufacturing processes, driving quality standards, customer service, and technical support:
Under a leadership team focused on long-term development, we apply a clear principle: "Do it, do the best". We employ top-tier R&D engineering talent, operate advanced production lines, and maintain dedicated after-sales support teams to meet quality expectations. Our performance data is validated by independent third-party inspection audits.
We build our operations around our engineering teams. Our design department can generate complete 3D CAD/CAM drawings within 24 hours of receiving customer specifications, ensuring that custom requirements are quickly reviewed, finalized, and scheduled for production.
