Compressor Pump
High Efficiency & Performance
The ZG series Roots blower delivers reliable high-pressure operation with large flow capacity and smooth performance. Its integrated impeller-shaft structure ensures rigidity, while precision hardened gears guarantee efficiency, low noise, and long service life.
Durable & Low Maintenance
Built with an aluminum alloy air-cooled oil tank, it operates at single-stage pressure up to 98 kPa without cooling water. The compact unit design with a self-tensioning belt tensioner makes operation and maintenance easy.
Versatile Applications
With flow rates of 0.6–113 m³/min, the ZG series is suitable for blower and vacuum applications. Its dual vertical/horizontal installation design makes it a convenient replacement for international models.
The ZG series Roots blower is a next-generation solution developed with our proprietary technology, based on imported American blower designs. As a leading industrial blower manufacturer, we deliver products with an outstanding price-performance ratio. The specially engineered casing ensures stable operation at high pressures while reducing operating noise. The impeller and shaft are fully integrated, providing superior rigidity for large airflow, strong pressure, and smooth high-speed operation. These advantages make the ZG blower and its Roots Vacuum Pump series widely recognized for world-class efficiency, durability, and performance across global industries.
