Formerly known as Shandong Zhangqiu Blower Works, we represent the peak of rotary lobe and positive displacement engineering in China. Over a continuous 50-year history of technological iteration, we have forged two Sino-Japanese Joint-Ventures and one United States subsidiary, marking our position as the pioneer Chinese blower manufacturer to establish overseas operational bases.
Our overall development strategy dictates a persistent framework: "Develop main business, pioneer new fields and innovate, cooperate to be a great company". Driven by the philosophy to "Do the Best", our modern industrial capabilities integrate full cycle design, simulation, precision machining, performance certification, and life-cycle management.
Our extensive catalog spans Roots Blowers, Centrifugal Blowers, Industrial Fans, Slurry and Vacuum Pumps, Pneumatic Conveying Systems, Electrical Control Equipment, and advanced MVR (Mechanical Vapor Recompression) systems designed for conservation, crystallization, and extreme environmental engineering.
On July 7th, 2011, Shandong Zhangqiu Blower achieved a listing on the Shenzhen Stock Exchange (Stock Code: 002598). This landmark event catalyzed the relocation and creation of our modern high-standard industrial park.
Our base in facts & figures:
Providing high-precision positive displacement equipment for global heavy industries across North America, Europe, and Asia.
To capture shifts in the international markets, Zhangqiu Blower established a dedicated foreign trade corporation and a localized branch in the United States. Today, our products are regularly exported to over 70 countries, including the United States, Germany, and Italy, supporting heavy chemical and water management companies.
As the Executive Director of the China General Machinery Industry Association (CGMA) and the Vice President Unit of the CGMA Fan Branch, we serve as the primary drafter of China's National Standards for Roots Blowers, defining regulatory tolerances and safety boundaries for the industry.
We are executing a strategic transformation plan. The company aligns with national industrial reforms by actively building three platform pillars: Intelligent Manufacturing, Environmental Engineering & Water Treatment, and New Materials Development & Application.
Zhangqiu Blower features domestic testing laboratories, material stress analyzers, and chemical calibration tools. Our facilities include over 100 sets of advanced processing equipment, such as Japanese and German CNC machining centers, five-axis machining centers, three-axis coordinate measuring machines (CMM), and ultrasonic nondestructive flaw detectors.
Using advanced Product Lifecycle Management (PLM) systems and Computer-Aided Manufacturing (CAM) tools, we implement Computer-Aided Process Planning (CAPP) and Computer-Aided Testing (CAT). These digital integrations improve manufacturing accuracy, reduce assembly tolerance stacks to the micron scale, and ensure stable performance curves for every batch.
Our R&D team includes experts supported by Special Allowances from the State Council, alongside senior structural engineers, material scientists, and thermal experts. Additionally, we collaborate with academic institutions like Tsinghua University, Xi'an Jiaotong University, and Shandong University to develop new impellers and energy-saving configurations.
Optimized rotor curves minimize gas backflow losses and dynamic shear friction, increasing mechanical efficiency and decreasing exhaust temperature variance.
Integrated countercurrent cooling systems and structural damping techniques lower radiated noise by 5-10 dB(A) compared to traditional industrial designs.
Custom containment configurations and mechanical seal barriers prevent process gases from leaking or mixing with lubricating oils, which is essential for hazardous environments.
How Zhangqiu Roots Blowers deliver critical performance across various industrial sectors.
In biological wastewater treatment, our ZG Tri-Lobe and SSR-K Roots blowers supply continuous aeration to bioreactors and activated sludge processes. Their stable pressure delivery maintains dissolved oxygen levels, optimizing microbial digestion without overheating under 24/7 duty cycles.
For transporting bulk powders, chemical granules, and materials like fly ash or cement, our high-efficiency positive displacement blowers deliver the velocity and pressure needed to move materials through dense or dilute phase systems without line blockages.
In zero-liquid-discharge (ZLD) installations, food processing, and chemical crystallization, our specialized vapor recompression blowers compress secondary steam, increasing its temperature and enthalpy to recycle thermal energy within the evaporator loop.
Working alongside our blowers, our TZJK-TD series ceramic slurry pumps handle abrasive and corrosive mineral slurries in beneficiation loops. Structural silicon carbide ceramic linings prevent erosion and extend service life compared to alloy parts.
In coal-fired and industrial power generation facilities, oxidation air blowers deliver ambient air into absorption towers, converting calcium sulfite to gypsum (CaSO4·2H2O) to scrub SO2 emissions and meet environmental standards.
For large-scale high-density aquaculture systems, our oil-free three-lobe blowers supply continuous, clean aeration air to ponds and tanks, ensuring dissolved oxygen stability and protecting aquatic livestock.
Located in the industrial manufacturing hub of Shandong Province, Zhangqiu Blower benefits from a robust localized supplier ecosystem. This integration covers high-grade raw casting suppliers, bearing manufacturers, and specialized gear cutting shops, enabling efficient component sourcing and short turnaround times.
Our domestic manufacturing network includes factories in Jiangsu, Guangdong, Hunan, and Gansu, which helps mitigate regional disruptions. Furthermore, we maintain strategic partnerships with domestic and international motor suppliers (such as Siemens, ABB, and WEG) to ensure quick system configuration and delivery.
We offer comprehensive engineering design support, delivering custom 3D CAD models and system configurations within 24 hours of customer request. Our streamlined processes reduce the time from order placement to port shipment, helping to decrease installation downtime for international projects.
Our close ties with local foundries guarantee uniform gray iron and ductile iron castings with minimal porosity.
Rotors are dynamically balanced to ISO G2.5 standards to reduce shaft vibration and protect adjacent bearings.
Automatic CNC machining maintains clearances between the lobes and casing to preserve high volumetric efficiency.
All completed units undergo full mechanical load and aerodynamic run testing prior to export packing.
Systematic verification processes and international standard compliance across our product lines.
Certified compliance with ISO9001 (Quality), ISO14001 (Environmental), ISO50001 (Energy Management), and ISO10012 (Measurement) systems.
Products carry CE markings and are certified for underground mining environments with the Safety Mark for Mining Products.
Supported by 69 authorized patents, including 5 invention patents, and 2 registered software copyrights.
A strong corporate culture is central to managing a large industrial enterprise. At Zhangqiu Blower, we value employee development, individual initiative, and accountability. This helps create alignment and supports continuous operational improvement.
By implementing structured talent development programs, our teams work toward aligned corporate goals, driving innovation in engineering design, quality control, and customer service.
Developing next-generation gas displacement technologies for a low-carbon economy.
