wages.
2. The offer for a single host price, excluding motor.
3. Special work requirements can be corrosion, sealing, high-pressure, intensive and other forms.For further details, please contact customer service.
| Product Application |
In terms of application, most of roots blower for the use of air blower. Their use in building materials, electric power, metallurgy, paper making, aquaculture and so on many fields.
| Blower working principle |
With the mutual engagement of the two gears, the inlet and outlet of the blower are not communicated directly. The impeller and the casing and the wall plate are enclosed into the base unit volume, so as to achieve the effect of conveying gas.

i, High-pressure Roots Blower Low noise
Hot-Sale Roots Air Blower for Reverse Cleaning of Filter Bags with adoption of helical tri-lobe roots rotors and the discharge port of special geometry, the airflow noise is much lower compared to typical straight-lobe roots blower. The noise level can be reduced by 8db in the band of low frequency; hence the noise in the surroundings of blower can be significantly improved.

ii, High adiabatic efficiency
High-pressure Roots Blower with design of helical tri-lobe roots rotors, Hot-Sale Roots Air Blower for Reverse Cleaning of Filter Bags the airflow pulsation is less and the air streamline would be more stable. Therefore the fluctuation in airflow is less and then the energy waste can be reduced. Additionally, the instantaneous backflow of discharge is lower by the design of special discharge port. Compared to straight-lobe roots blower, the adiabatic efficiency can be raised up to 20%.
