Core Advantages: American Technology & Dependable Quality

1. Advanced Technical Support

Adopting mature American Roots blower technology, the ZG Series has been optimized in structure and upgraded in materials to adapt to global operating conditions. The precision-machined rotor and casing are designed with high tightness, effectively reducing internal leakage and ensuring stable air volume output during long-term continuous operation. The high-precision ground and nitrided gear transmission system ensures smooth power transmission, prolonging the service life of key components to more than 8 years.

2. Superior Performance Parameters

The ZG Series covers a full range of specifications to meet diverse industrial requirements:

•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 selection: Standard cast iron structure; stainless steel can be customized for corrosive media, adapting to harsh working environments such as high humidity and mild corrosion.

•Energy-saving and low-noise: Optimized impeller design reduces aerodynamic noise, with operating noise controlled below 85dB(A) under standard conditions. The motor efficiency reaches up to 86%, achieving energy-saving operation.

3. Durable & Easy to Maintain

•Integrated casting structure ensures high rigidity and vibration resistance, suitable for complex industrial sites with unstable foundations.

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

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

Wide Applications: Powering Various Industries

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

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

•Chemical industry: Inert gas transportation and process gas circulation

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

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