Engineered for extreme environments, delivering optimal thermodynamic efficiency, low noise emission, and high structural reliability.
Formerly known as Shandong Zhangqiu Blower Works, we represent more than 50 years of specialized history in blower design, engineering, and manufacturing. Having established two Sino-Japanese Joint-ventures and a dedicated branch office in the USA, we stand as the first enterprise in China's blower industry to expand its physical operations overseas. As the leading enterprise in the Zhangqiu industrial region, our primary Roots Blower systems consistently rank first in domestic market occupancy.
Our core development blueprint centers on: "Develop main business, pioneer new fields and innovate, cooperate to be a great company", backed by our fundamental working philosophy: "Do the best". Today, we stand as a highly diversified, modern enterprise integrating advanced research and development, smart manufacturing, and comprehensive global sales. Our expansive portfolio spans Roots Blowers, Centrifugal Blowers, Heavy-Duty Industrial Fans, Slurry and Desulfurization Industrial Pumps, Pneumatic Conveying Systems, Electrical Equipment, and full-scale MVR Evaporation, Concentration, and Crystallization systems.
In 2005, the company relocated to a newly built, high-standard modern industrial park. This expansive campus covers 430,000 square meters and features cutting-edge processing centers and comprehensive administrative offices. This facility laid the foundation for our rapid growth and seamless global joint ventures.
On July 7th, 2011, our enterprise reached a major milestone by listing on the Shenzhen Stock Exchange (Stock Code: 002598). This capital infusion accelerated our engineering research and expanded our production capabilities.
By 2020, our parent company achieved an annual operating revenue of 1.5 billion yuan, with a profit of 150 million yuan (including our direct holdings and subsidiaries). Today, we operate 20 holding companies with dedicated production bases in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, supported by four state-of-the-art R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
As the executive director unit of the China General Machinery Industry Association's Fan Branch, we lead the national standardization committee in drafting the official standards for Roots Blowers.
We continuously drive technological innovation by establishing the first provincial-level enterprise technology center in Zhangqiu. Our production capabilities include:
We leverage a professional research team comprising experts receiving State Council special allowances, senior engineering researchers, and doctoral specialists.
Our development center utilizes high-precision processing and inspection equipment that set industry standards:

A Comprehensive Analysis of Modern Compressed Air and Heavy Fluid Machinery Technologies.
The industry is rapidly transitioning from traditional belt-driven and geared assemblies to high-frequency Permanent Magnet Synchronous Motors (PMSM) and Active Magnetic Bearing (AMB) systems. By eliminating physical bearings and lubricating oil, magnetic levitation blowers achieve mechanical efficiencies above 95%, reduce maintenance costs, and supply 100% oil-free compressed air. Our engineering team continues to advance these motor controls for extreme high-altitude and high-temperature environments.
Using Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA), we optimize the shape of our tri-lobe Roots rotors and centrifugal impellers. Designing 3D twisted impellers reduces internal return leakage and gas pulsation, lowering overall noise levels. This profile optimization enables higher compression ratios per stage, allowing our single-stage high-speed centrifugal systems to match the performance of older, multi-stage configurations.
Future industrial plants require smart, interconnected devices. We integrate real-time sensor arrays into our blowers to monitor temperature, vibration, dynamic pressure, and oil quality. This data feeds into PLC cabinets and cloud platforms, where machine learning algorithms predict bearing wear and thermal strain. This predictive maintenance system helps prevent unplanned downtime in critical processes.
Supporting major municipal, chemical, energy, and material-handling infrastructures worldwide.
Aeration tanks are the largest energy consumers in municipal sewage plants. Our PMSM direct-drive turbo blowers and ZG tri-lobe Roots packages provide continuous, energy-efficient airflow. They adapt to fluctuating chemical oxygen demand (COD) levels, reducing plant energy costs by up to 30%.
For handling bulk powders, plastic pellets, fly ash, and granular chemicals, our high-volume roots blowers (like the TRK6008A series for dry bulk trucks) supply constant volume against varying pipe resistance. This ensures smooth, plug-free pneumatic conveying across long distances.
Our VR series Roots steam compressors serve as the heart of modern zero-liquid-discharge (ZLD) systems. By compressing secondary steam to raise its thermal energy, our systems allow industrial waste heat to be recycled, reducing boiler fuel consumption in chemical plants.
Our manufacturing base operates under Industry 4.0 principles, ensuring high quality and reliable delivery.
By integrating PLM database systems, computer-aided process planning (CAPP), and computerized testing (CAT), we ensure consistent, high-precision machining. Our 5-axis CNC centers machine complex impellers with tight tolerances, minimizing balancing issues and vibration.
This vertical integration enables us to manage raw material casting, dynamic balancing, assembly, and testing in-house. We maintain a stable supply chain that minimizes global component delays, helping us deliver custom-configured blowers on schedule.
We support global engineering projects with equipment designed to meet local international standards.
Our branch in the United States and our global service networks provide technical consultation, spare parts, and commissioning support.
Whether replacing drop-in equipment in a North American wastewater plant with our imperial-dimensioned ZZ series Roots blowers or supplying CE-compliant high-volume centrifugal fans to European chemical projects, we offer compliant, reliable solutions.
Detailed technical answers to common queries from procurement specialists and utility engineers.
Heavy industrial steam compressors, large-volume Roots blowers, and specialized truck-mounted conveying units.
"Cohesion produces strength, unity brings glory."
Our business strategy focuses on three industrial platforms: intelligent manufacturing, environmental protection/water treatment, and advanced materials development.
By prioritizing staff development, we foster a collaborative, results-oriented workspace. This human-centric approach drives team engagement and supports our focus on product quality and technical innovation.
Building long-term growth through collaboration and engineering expertise.
