The blower adopts a newly designed three-lobe impeller profile (patent applied), which significantly improves air tightness and reduces internal leakage compared to traditional two-lobe types. This ensures higher volumetric efficiency and stable flow output under various working conditions.
The 3H Roots Blower is engineered with a noise-reducing casing structure (patent: Multi-blade impeller inlet casing), high-precision machined components, and dynamic rotor balancing. These features contribute to a dramatic reduction in noise and vibration, making it suitable for noise-sensitive environments.
Thanks to its precision-machined rotors and optimized internal clearances, the blower produces less airflow pulsation, resulting in quieter, smoother, and more stable operation even at high pressure and flow.
With all major components—such as the casing, impellers, and shafts—processed through CNC machining and strict quality control, the blower offers superior durability and long service life, even in harsh industrial environments.
The 3H series maintains a 100% oil-free gas path, ensuring clean air output with no risk of contamination, which is especially important for environmental, aquaculture, and chemical processing applications.
