ZG Series Roots Blowers

ZG Series Roots Blowers: American Technology-Driven, Reliable Core for Global Gas Transmission

As a flagship product line of Shandong Zhangqiu Blower Co., Ltd. (Stock Code: 002598) – a listed enterprise with over 50 years of blower manufacturing heritage – the ZG Series Roots Blowers inherit advanced American technology and integrate decades of localized optimization experience. With its stable performance, wide applicability and easy maintenance, it has become the trusted choice for gas transmission in multiple industries worldwide, standing out in the domestic market with a leading market share.

Core Advantages: American Technology, Reassuring Quality

1. Advanced Technical Foundation

Derived from mature American Roots blower technology, the ZG Series undergoes rigorous structural optimization and material upgrades for global working conditions. The precision-manufactured rotor and casing adopt a high-tightness fit design, effectively reducing internal leakage and ensuring stable air volume output even under long-term continuous operation. The gear transmission system with high-precision grinding and nitriding treatment achieves smooth power transmission, extending the service life of key components to over 8 years.

2. Excellent Performance Parameters

Covering a comprehensive application range 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, with stainless steel customization available for corrosive medium scenarios, adapting to harsh working environments such as high humidity and mild corrosion.

Energy-saving & low-noise: Optimized impeller profile design reduces aerodynamic noise, with operating noise controlled below 85dB(A) (standard working conditions), and motor efficiency up to 86% to achieve energy-saving operation.

3. Robust & Easy-Maintenance Design

The integrated cast structure ensures high rigidity and resistance to vibration, suitable for complex industrial sites with unstable foundations.

Key wearing parts are standardized and universally applicable, enabling quick replacement without professional tools, minimizing maintenance downtime.

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

Wide Application Fields: Empowering Multiple Industries

With its reliable gas transmission capabilities, the ZG Series Roots Blowers are widely used in:

Sewage treatment: Aeration systems for municipal and industrial wastewater treatment plants

Chemical industry: Transportation of inert gases, process gas circulation

Metallurgy: Auxiliary ventilation for smelting processes, gas conveying in blast furnaces
