Efficiency Rotary Air Blower: American Tech-Infused, The Global Benchmark for Reliable Gas Transmission

As the flagship product line of Shandong Zhangqiu Blower Co., Ltd. (Stock Code: 002598) — a listed enterprise with more than 50 years of professional blower manufacturing experience — the ZG Series Roots Blowers are built on advanced American technology and integrated with decades of localized optimization. Boasting stable performance, wide applicability and easy maintenance, this series has become the preferred choice for gas transmission across multiple industries worldwide, and maintains a leading market share in the domestic sector with its outstanding strength.

Core Advantages: American Technology, Premium Quality You Can Trust

1. Cutting-Edge Technical Foundation

Based on mature American Roots blower technology, the ZG Series has undergone rigorous structural optimization and material upgrades to adapt to global working conditions. The precision-manufactured rotor and casing adopt a high-tightness fitting design, which effectively reduces internal leakage and ensures stable air volume output even during long-term continuous operation. The high-precision ground and nitrided gear transmission system enables smooth power transmission, extending the service life of key components to more than 8 years.

2. Excellent Performance Parameters

The ZG Series covers a comprehensive range of specifications to meet diverse industrial needs:

•Flow capacity: 0.43~184.4 m³/min (blower) / 0.52~183.9 m³/min (vacuum pump)

•Pressure range: 9.8~98 kPa (blower)

•Vacuum degree: -9.8~-50 kPa (vacuum pump)

•Material options: Standard cast iron structure; stainless steel customization is available for corrosive medium scenarios, making it adaptable to harsh working environments such as high humidity and mild corrosion.

•Energy-saving & low-noise: The optimized impeller profile design reduces aerodynamic noise, with the operating noise controlled below 85dB(A) under standard working conditions. Meanwhile, the motor efficiency reaches up to 86%, realizing energy-saving operation.

3. Durable & Easy-Maintenance Design

•The integrated casting structure ensures high rigidity and vibration resistance, making it suitable for complex industrial sites with unstable foundations.

•Key wearing parts are standardized and universally compatible, allowing quick replacement without professional tools, thus minimizing maintenance downtime.

•No special lubrication system is required for daily operation; regular inspection of seals and bearings is sufficient to maintain stable performance, reducing operational costs effectively.

Wide Application Fields: Empowering Multiple Industries Globally

With its reliable gas transmission capacity, the ZG Series Roots Blowers are widely applied in various industries:

•Sewage treatment: Aeration systems in municipal and industrial wastewater treatment plants

•Chemical industry: Transportation of inert gases and circulation of process gases

•Metallurgy: Auxiliary ventilation for smelting processes and gas conveying in blast furnaces

•Food & pharmaceutical: Drying, vacuum packaging, and clean gas transmission

•Environmental protection: Biogas collection and auxiliary systems for flue gas treatment

•Building materials: Ventilation in cement production processes and powder conveying
