Shandong Zhanggu 3H Series Roots Blower – Efficiency Enhanced, Reliability Reinforced
The 3H Series Roots Blower from Shandong Zhanggu is a new-generation high-performance product developed based on the proven manufacturing experience of the RR Series. Building on nearly 60 years of design and production expertise, Zhanggu has optimized both structure and rotor design to achieve greater efficiency and smoother operation.
Product Features：
1.Technical Inheritance and Innovative Upgrade
The 3H Series adopts a three-lobe rotor design, replacing the traditional two-lobe structure of the RR Series. This improvement significantly reduces air pulsation at inlet and outlet, minimizes noise and vibration, and ensures more stable airflow — resulting in higher volumetric efficiency and quieter performance.
2.High Efficiency and Energy Saving
With precisely machined rotors and optimized internal clearances, the 3H Series delivers greater air output efficiency under the same operating conditions while lowering energy consumption. Its high-efficiency design makes it ideal for applications in environmental protection, pneumatic conveying, water treatment, metallurgy, and chemical industries.
3.Reliable Manufacturing Quality
Following the philosophy of Precision Manufacturing, Zhanggu uses high-strength materials and advanced CNC machining to ensure superior quality and consistency. Every blower undergoes strict dynamic balancing and assembly control, ensuring long-term reliability and durability in continuous operation.
4.Easy Maintenance and Stable Operation
The 3H Series features a compact structure, user-friendly maintenance, and a well-designed lubrication system for extended service life. The blower runs smoothly with low noise, making it suitable for a wide range of industrial continuous-duty applications.
