i, High-pressure Roots Blower Low noise
High quality Wellna brand 2WN740-7GH47 oxygen making use high pressure roots blower 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, High quality Wellna brand 2WN740-7GH47 oxygen making use high pressure roots blower 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%.

iii, High-pressure Roots Blower Super Energy saving
Compared to the typicalHigh quality Wellna brand 2WN740-7GH47 oxygen making use high pressure roots blower under the same operation conditions of discharge pressure and airflow volume, the power consumption of helical tri-lobe roots blower will be lower by 20.
