Engineered for extreme workloads, chemical process reliability, and significant energy savings across heavy industries.
Shandong Zhangqiu Blower Co., Ltd. (formerly Shandong Zhangqiu Blower Works)
With over 50 years of dedicated blower design, manufacturing technology, and process refinement, ZCBC stands as an industry pioneer. As the first enterprise in China's blower sector to establish an overseas division, we operate two Sino-Japanese Joint-ventures and a direct branch in the United States. We maintain dominant market occupancy in the Roots Blower space, steering the industry toward automated, low-emission, and energy-conserving operations.
Guided by our corporate strategic vision—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—and our uncompromised work concept—"Do the best"—we have structured a multi-disciplinary manufacturing ecosystem that includes Roots Blowers, Centrifugal Blowers, Industrial Fans, Specialized Slurry & Vacuum Pumps, Pneumatic Conveying Systems, Electrical Control Systems, MVR Evaporative Systems, and Waste Water Treatment solutions.
Mapping the transition of pneumatic machinery from high-consumption mechanical systems to smart, high-frequency, oil-free designs.
Strict environmental policies demand absolute avoidance of lubricant contamination in aeration channels. Magnetic suspension and air foil bearing centrifugal technologies are rapidly replacing standard mechanical systems, providing completely oil-free airflow while eliminating wear components.
Fixed-speed ventilation systems are being replaced by VFD-driven dynamic loops. By modulating impeller speed based on instantaneous pipeline demands, industrial sites routinely experience energy consumption reductions of 20% to 40%.
Advanced Computational Fluid Dynamics (CFD) modeling allows the production of multi-dimensional twisted-leaf impellers. These optimized curves reduce aerodynamic drag, minimize localized air-shear noise, and extend mechanical lifespan under harsh conditions.
These shifts define the design philosophy at ZCBC. In an era where energy usage determines industrial profitability, our R&D aligns directly with global decarbonization initiatives, introducing high-speed direct-drive models, acoustic-attenuated shrouds, and active magnetic suspension control.
Balancing capital expenditure (CAPEX) with long-term operational efficiency (OPEX) in pneumatic systems procurement.
Global EPC contractors and procurement managers require rapid engineering response times to ensure smooth execution of infrastructure projects. At ZCBC, we address these detailed planning needs by providing:
Whether sourcing for a high-volume aeration facility, a chemical crystallization loop, or a mining process system, ZCBC provides clear technical specifications and robust compliance profiles to simplify site installations.

| Multistage Centrifugal (C Series) | 20 to 150 kPa | 15 to 400 m³/min | High (at design point) | Coal Washing, Floatation, Smelting, Large Gas Distribution |
| Air Foil Bearing Turbo Blower | 30 to 120 kPa | 10 to 300 m³/min | Excellent (up to 35% savings) | Municipal Wastewater Aeration, Fermentation, Clean Rooms |
| Magnetic Suspension Centrifugal | 30 to 200 kPa | 20 to 450 m³/min | Premium (30-40% savings) | Ultra-scale Treatment, Heavy Process Gas Handling |
High-performance engineering solutions for complex processing environments and resource recovery setups.
Continuous biological treatment demands steady oxygen delivery. ZCBC supplies highly efficient Roots and Centrifugal blowers equipped with robust sealing and noise-control options, designed to deliver steady oxygen flows while reducing operating costs.
Coarse ore processing and coal preparation plants require heavy-duty slurry pumps. Our TZJ and ceramic slurry pumps feature hard metal casings and chemical-resistant polyurethane wet ends, providing reliable service life when handling aggressive media.
Mechanical Vapor Recompression loops require high performance and precise temperature management. ZCBC designs specialized centrifugal vapor compressors that recompress low-pressure waste steam, significantly reducing energy footprint on site.
ZCBC maintains a robust technological infrastructure. Our machining floors are equipped with nearly 100 sets of imported high-precision equipment, including CNC machining centers, five-axis machining centers, three-axis measuring systems, and non-destructive ultrasonic flaw detectors from Japan and Germany.
Leveraging our Product Lifecycle Management (PLM) systems and Computer-Aided Manufacturing (CAM) tools, we shorten the design-to-delivery pipeline while maintaining consistent build tolerances for our complex rotor profiles.
Managing local regulations, certification standards, and supply chain logistics for international deliveries.
ZCBC is fully certified under ISO9001 (Quality Management), ISO14001 (Environmental Protection), ISO50001 (Energy Management), and ISO10012 (Measurement Systems). This system-level alignment ensures repeatable quality and tracebility for every manufactured unit.
Our products carry all key industrial approvals, including CE marking for European markets, 3C mandatory safety certifications, and specific safety markings required for deep mining applications.
With an established subsidiary in the United States, joint ventures, and distribution networks in over 70 countries, we provide reliable shipping, localization support, and field service across key regions.
To ensure continued technological development, ZCBC collaborates closely with leading universities and research institutes, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University.
Answers to common technical queries regarding configuration, deployment, and performance of our process air systems.
"Cohesion produces strength, unity brings glory."
At ZCBC, our culture focuses on continuous improvement and taking responsibility. We believe that professional management starts with respecting and cultivating our workforce. Under the leadership of Chairman Fang Rungang (serving since 1997), we promote independent problem-solving alongside unified corporate goals.
By supporting our engineering and design teams with postgraduate workstations and close academic ties, we translate individual expertise into high-performance product developments that serve our customers globally.
