Engineered for unmatched performance, operational longevity, and optimized power consumption across demanding industrial ecosystems.
Founded originally as Shandong Zhangqiu Blower Works, Shandong Zhangqiu Blower Co., Ltd. (ZCBC) has spent over half a century pioneering advanced flow dynamics, aerodynamic design, and precision manufacturing. As a listed enterprise on the Shenzhen Stock Exchange (Stock Code: 002598) since July 2011, we have built a stellar reputation as a formidable leader in global turbomachinery and industrial blower development.
Our overall strategic directive is to "Develop main business, pioneer new fields and innovate, cooperate to be a great company." This philosophy drives us to continuously refine our production of Roots blowers, centrifugal blowers, industrial pumps, and advanced waste water treatment engineering platforms.
Understanding the physics, aerodynamics, and structural mechanisms that make Single Width Single Inlet (SWSI) blowers the primary choice for high-pressure, heavy-duty processing.
Single Inlet Centrifugal Blowers direct process air or gas through a single axial inlet directly into the center of the rotating impeller. This configuration optimizes performance in high-static-pressure, lower-volume applications. It enables the use of specialized shaft seals, gas-tight casings, and heavy insulation, which are harder to deploy in double-inlet fans.
Our blowers employ airfoil-shaped backward-curved impellers, custom-designed using advanced Computational Fluid Dynamics (CFD). This design yields static efficiency ratings exceeding 85%, significantly lowering power requirements and minimizing structural vibration at elevated rotational speeds.
For chemical and power applications, our single-inlet blowers are constructed with premium structural alloys. Options include duplex stainless steels, Hastelloy, or protective wear-resistant coatings (e.g., tungsten carbide spray), enabling operation in gas temperatures up to 800°C.

Demonstrating unmatched flexibility and engineering adaptation in major global processing facilities.
Our single-inlet centrifugal blowers provide the constant, high-volume flow needed for biological wastewater basins. Their robust pressure profiles easily overcome hydro-static backpressure at the diffusers, ensuring optimal oxygen transfer while lowering energy costs.
Widely deployed in cement, alumina, and food processing plants, these blowers deliver the high pressure required to move dry bulk materials. They support both positive and negative pressure systems, ensuring steady conveying velocities and preventing pipe blockages.
In thermal power plant desulfurization plants, single-inlet blowers inject oxidation air into absorber towers. Built with corrosion-resistant steels and advanced shaft seals, they stand up to wet, acidic environments and run continuously with minimal downtime.
How our vertically integrated production hubs and advanced computational systems guarantee rapid dispatch and uncompromising quality control.
Spread across a massive 430,000 m² high-standard modern industrial park, ZCBC leverages massive scale, streamlined logistics, and localized vendor ecosystems to buffer against global supply chain disruptions. With additional manufacturing nodes in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, we easily maintain a steady output of custom blower assemblies year-round.
Our design team utilizes the Product Lifecycle Management (PLM) system, Computer-Aided Process Design (CAPP), and CAM technology to compress the standard product development cycle. We can deliver complete, detailed 3D CAD models and performance drawings within 24 hours of customer confirmation, accelerating field installation timelines.
At ZCBC, we believe our engineering expertise is our greatest asset. Our R&D division is staffed by senior turbomachinery experts, doctoral researchers introduced through Jinan City's prestigious '5150' project, and specialists receiving state council subsidies. A dedicated postgraduate workstation maintains close research ties with top-tier universities, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University.
This academic foundation has produced major innovations, including countercurrent cooling systems, dynamic fan noise reduction, anti-wear impellers, two-stage tandem configurations, grease-lubricated bearing designs, and smart, cloud-connected blower monitoring systems.
Every single inlet centrifugal blower and slurry pump we manufacture is built to meet international compliance frameworks. ZCBC is certified under:
A look at how we are incorporating next-generation digital and mechanical features to meet the global demand for sustainable industrial machinery.
Our R&D division is integrating electromagnetic bearing technology into our higher-speed centrifugal blower series. Magnetic bearings eliminate physical contact, meaning zero wear, zero lubrication oil, and drastically reduced maintenance overhead for plants pursuing complete process purity.
Future iterations of our centrifugal systems will feature integrated cloud-monitoring sensors. These systems track vibration frequencies, bearing temperatures, and pressure fluctuations in real-time, forecasting maintenance requirements and preventing unplanned outages.
Transitioning from traditional belt drives and induction motors to high-speed PMSM direct drive systems lets us eliminate mechanical transmission losses. This change reduces package footprints and boosts overall system efficiency by up to 15%.
