High-efficiency aerofoil systems and slurry transport machinery designed for the most demanding plant operations.
Innovating the fluid dynamics frontier: From high-volume axial configurations to complex pressure-boosting centrifugal fans.
Utilizing proprietary computational fluid dynamics (CFD) packages to balance volumetric flow rate ($Q$) and total static pressure ($P_s$). Every impeller blade angle, geometry, and shroud contour is optimized for system impedance curves, minimizing turbulent shear loss.
Smart automation controls match flow demands in real-time. By deploying IE4 and IE5 permanent magnet synchronous motors paired with variable frequency drives, our fans eliminate throttling losses and reduce peak energy demand by up to 35%.
Equipped with telemetry arrays measuring temperature, vibration vectors, and pressure differences. Integrating these monitors into cloud-based SCADA systems ensures predictive maintenance cycles, halting sudden breakdowns and extending service lives.
Founded in 1957 and boasting over 50 years of relentless engineering evolution, Shandong Zhangqiu Blower Co., Ltd. (ZCBC) is a prominent leader in the global air handling and fluid transport industry. From our roots as a key machinery manufacturing pioneer, we have evolved into a publicly listed enterprise on the Shenzhen Stock Exchange (Stock Code: 002598).
We pride ourselves on being a multi-faceted manufacturer that handles the design, production, testing, and servicing of Roots blowers, multi-stage centrifugal blowers, single-stage high-speed turbo blowers, industrial fans, slurry pumps, and turn-key mechanical vapor recompression (MVR) evaporation systems.
Our operation is built on our core philosophy: "Do the best". Operating from our massive 430,000 m² high-standard industrial park built in 2005, ZCBC coordinates four advanced production bases across Wuxi, Dongguan, Chenzhou, and Jinchang, supported by four cutting-edge R&D centers in Beijing, Shanghai, Wuxi, and Shijiazhuang.
Our innovation is driven by a deep pool of engineering experts, including researchers receiving special allowances from the State Council. Backed by our dedicated postgraduate research workstations, ZCBC actively collaborates with prestigious academic institutions such as Tsinghua University, Xi'an Jiaotong University, Shandong University, and the China University of Mining and Technology.
This commitment to R&D ensures we continually implement advanced technologies, including countercurrent cooling chambers, smart acoustic dampening housings, anti-sticky wear-resistant impeller coatings, heavy-duty tandem seals, and twisted-leaf rotor geometry designs.
To assure rapid customization, our design team leverages advanced PLM, CAD, and CAPP platforms to supply complete engineering submittals and detailed 3D drawings within 24 hours of customer requests.
Proven capabilities verified by third-party testing agencies and global industrial installations.

Custom engineering solutions tailored for heavy industries, hazardous plants, and municipal facilities.
Deep shaft mining demands rugged air systems. Our high-pressure axial fans deliver fresh air across miles of underground channels. Utilizing spark-resistant aluminum-bronze impellers and explosion-proof (ATEX/IECEx) motor housings, they ensure a safe working environment under extreme operating conditions.
Handling flammable, toxic, and highly corrosive chemical gases requires gas-tight designs. ZCBC provides heavy-duty centrifugal blowers with double mechanical seals, inert gas purging systems, and premium stainless steel or titanium alloys. These units offer long-term chemical resistance, preventing hazardous leaks.
Biological aeration is a major energy consumer in water treatment plants. ZCBC offers a range of high-efficiency blowers, from multi-stage centrifugal systems to advanced air foil bearing and magnetic levitation units. These systems cut plant operating costs by providing oil-free oxygen delivery and flexible flow controls.
Our production facilities utilize modern digital manufacturing systems to guarantee precision and short lead times. Our machining workshops house over 100 sets of imported precision equipment, including five-axis CNC machining centers, automated horizontal lathes, three-axis coordinate measuring machines (CMM), and advanced ultrasonic flaw detection devices imported from Germany and Japan.
By integrating our Product Lifecycle Management (PLM) database with Computer-Aided Manufacturing (CAM) networks, we maintain absolute design consistency from the initial CAD file to the final assembly line. Raw materials are sourced from leading steel mills and casting partners, ensuring high metallurgical stability and fatigue resistance for all impellers, shafts, and casings.
This vertically integrated manufacturing model shields our global customers from supply chain disruptions. By keeping core casting, machining, dynamic balancing, and performance testing in-house, ZCBC guarantees on-time delivery even for complex, custom engineering projects.

Certified under ISO 9001 for quality systems, ISO 14001 for environmental management, and ISO 50001 for energy efficiency standards.
Fully compliant with CE directives, China's 3C safety standards, and specialized safety certificates for underground mining equipment.
Our in-house laboratories and test setups are certified to ISO 10012, ensuring highly accurate measurement and instrumentation data.
Key design considerations to optimize efficiency and minimize total cost of ownership (TCO).
Axial Fans: Best suited for high volumetric flow rates under relatively low static pressures. Air flows straight through parallel to the impeller shaft. Common applications include tunnel ventilation, radiator cooling, and building exhaust.
Centrifugal Fans: Ideal for high static pressures and harsh gas streams. Air enters axially and turns 90 degrees, exiting radially. The impeller adds energy through centrifugal force. Ideal for dust extraction, flue gas desulfurization, and pneumatic conveying.
Selecting the right materials is critical for fan reliability. For high-temperature setups (up to 800°C), specialized stainless steel or nickel alloys prevent thermal creep. In abrasive environments, such as mining ventilation or cement manufacturing, we apply tungsten carbide or chromium carbide coatings to the impeller blades to protect them from erosion.
For corrosive atmospheres, titanium casings, specialized coatings, or composite materials (FRP) prevent chemical corrosion, ensuring long-term structural integrity.
