Product Features
The impeller uses an advanced three-lobe design with a high area utilization coefficient and integral shaft structure for rigidity and balance. This ensures the blower maintains high pressure and large flow at high speed with minimal vibration. The optimized aerodynamic design also enhances energy efficiency while reducing operational noise. Coupled with a Roots Vacuum Pump, the system provides stable vacuum generation and consistent airflow for demanding industrial applications. The combination of advanced impeller design and integrated rotor technology maximizes output, reduces energy consumption, and ensures reliable performance under continuous operation.
Transmission & Drive
The ZQG series employs a proprietary permanent magnet direct-drive technology, integrating the motor and blower rotor on a single shaft. This eliminates the need for belts or couplings, achieving 100% transmission efficiency. The design improves overall reliability, reduces maintenance requirements, and enhances operational stability. This direct-drive configuration, combined with a Roots Vacuum Pump, ensures seamless operation in vacuum or pressure systems while minimizing energy losses. Its innovative “blower-motor integration” approach delivers precise performance control, smooth operation, and long-term durability, making it ideal for modern industrial processes requiring high-efficiency air or vacuum generation.
