Explore our elite range of high-efficiency roots blowers, centrifugal fans, turbo blowers, and heavy-duty slurry pumps engineered for harsh industrial environments.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) represents over five decades of absolute dedication to blower design, custom fan engineering, and global manufacturing technology. As the pioneer of the Chinese blower industry, we established the first domestic enterprise to form two Sino-Japanese Joint-ventures and launch a dedicated USA branch. We operate as the leading enterprise in the Zhangqiu local industrial landscape, where our dominant product lines—particularly our high-capacity Roots Blowers and customized Dust Centrifugal Fans—maintain top-ranked market occupancy across China and key international industrial regions.
Our overall developing strategy is clear: "Develop main business, pioneer new fields and innovate, cooperate to be a great company." Combined with our strict working concept, "Do the best," we have transformed into a highly diversified, modern enterprise. Today, our engineering capacities seamlessly integrate design, manufacture, and sales across multiple core product disciplines including Roots Blowers, Centrifugal Blowers, Dust Centrifugal Fans, heavy-duty Industrial Slurry Pumps, advanced Pneumatic Conveying Systems, Electrical Control Equipment, and cutting-edge MVR Evaporation, Concentration, and Crystallization systems.
Moving forward with rapid global industrial shifts, we relocated to our high-standard, modern industrial park in 2005. Spanning a magnificent footprint of 430,000 square meters, this high-tech manufacturing hub features complete CNC processing facilities, test beds, and an administrative complex designed to support close collaboration with overseas companies and fast-track product innovations.
This path of sustainable expansion reached a critical milestone on July 7, 2011, when the company officially listed on the Shenzhen Stock Exchange (Stock Code: 002598). By 2020, our parent company realized an operating income of 1.5 billion yuan and a profit of 150 million yuan. Today, Zhang Drum operates 20 holding companies and has established four massive manufacturing bases across China in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, supported by dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Understating the fluid dynamics, wear resistance, and thermodynamic optimization behind industrial dust centrifugal fans.
Dust-laden airflows require specialized impeller configurations. We manufacture backward-curved, backward-inclined, and radial-tip impellers. Backward-curved impellers offer up to 88% static efficiency while preventing severe dust accumulation thanks to optimized gas velocity distribution curves across the blade chord.
To combat abrasive dust (such as fly ash, cement particles, and quartz), our impellers are treated with thermal-sprayed Tungsten Carbide (WC-Co) or Chromium Carbide overlays. In highly corrosive environments, advanced ceramic tile linings are applied to prevent premature rotor failure, reducing wear by up to 10x.
Operating at high tip speeds requires extreme rotor balance. Every impeller undergoes double-plane dynamic balancing in our ISO 1940 G2.5 class testing chambers. This reduces residual imbalance, eliminates vibration transmission to the bearings, and significantly extends the operational lifespan of the direct-drive or V-belt shaft assemblies.
The technical roadmap for our dust centrifugal fans focuses heavily on matching high flow-rate demands with energy conservation metrics. Industrial ventilation systems account for up to 40% of standard plant power consumption. By implementing Computational Fluid Dynamics (CFD) simulation tools alongside Finite Element Analysis (FEA), our R&D centers optimize the volute casing spiral and inlet cone geometry. This minimizes turbulence, prevents localized recirculation zones, and ensures the lowest possible pressure drop across the fan housing.
Why leading procurement divisions choose Shandong Zhangqiu Blower for high-scale, heavy industrial ventilating projects.
Global procurement specialists are tasked with minimizing Total Cost of Ownership (TCO) while ensuring maximum plant uptime. A "cheap" dust centrifugal fan is not simply one with a low purchase price, but one that provides unmatched energy efficiency, minimal maintenance demands, and readily available replacement parts over a 20-year operating life.
Engineered to deliver continuous, high-volume fluid movement under the most severe industrial parameters.
Our SSR-K and ZG Series Roots Blowers supply stable, oil-free aeration to biological treatment tanks, maintaining optimal dissolved oxygen levels for microbiological activity while drastically reducing energy consumption compared to traditional multi-stage fans.
For mineral flotation, pneumatic conveying of tailings, and furnace combustion air supply, our high-pressure geared turbo blowers and ceramic slurry pumps withstand high particulate density and continuous duty cycles.
Mechanical Vapor Recompression (MVR) systems demand precise pressure boosts under elevated temperatures. Our custom single and multi-stage centrifugal blowers handle corrosive vapors with special shaft seals and corrosion-resistant alloys.
By focusing on dust centrifugal fan technology, we support heavy industries like cement manufacturing and coal-fired power plants. These systems generate massive quantities of abrasive particulate matter that must be extracted efficiently to meet environmental emission standards. Our heavy-duty fans are placed downstream of electrostatic precipitators or baghouse filters, handling gas temperatures exceeding 250°C and dust loads that would destroy standard commercial fans within weeks.
