General Industrial 30% Energy Saving 132kw 175 HP Oil Free Screw Air Blower for Water Treatment

Product Details

Features and Advantages

1. High Efficiency and Energy Saving: A core advantage. Utilizing permanent magnet variable frequency technology

and internal compression principle, it saves approximately 30% more energy than traditional Roots blowers.

2. Absolutely Oil-Free: Delivers pure gas, meeting the needs of industries with stringent air quality requirements.

3. Low Noise and Vibration: Smooth operation with noise levels typically below 75 decibels, providing a more

comfortable working environment.

4. Intelligent Control: Integrated intelligent controller for real-time monitoring and easy maintenance.

5. Long Lifespan and Low Maintenance: The main unit is designed for a long lifespan; the main maintenance task is

replacing the filter element.
