1. Used in sewage aeration and aquaculture.

2. Roots blower is a volumetric blower, and the output air volume is proportional to the rotation speed. Adopting a spiral structure, the airflow pulsation is small and the load is small.

3. It is equipped with high-precision hard-tooth surface synchronous gears, which are strong and wear-resistant and have a long service life.

4. No need to add engine oil for lubrication.

5. Exclude that air volume is closely related to pressure and motor speed, and adjust the fan speed according to the actual situation.
