Quiet type vertical-type roots blower

Key Features
The mini-size of re-circulated and cooling vertical-type roots blower.


SUPER QUIET!!!Hot Deal to Europe!!!!


Quite type re-circulated and cooling vertical-type roots blower:

•Low Noise: The two-stage muffling and the soundproof room of the inlet and the erect silencer of the outlet will low down the noise effectively.
•High Efficiency: The symmetrical design of the lobe with the CNC manufacturing will make the roots blower more efficiency.
•To cool down the bearing compulsively by the cold air: Making the cold air from the inlet around the bearing to avoid the high temperature damaging and the lubrication deteriorating. Therefore, the duration to replace the oil will be extended.
•Small Vibration & Long Durability: Due to the vertical design of the blower, the lobe with the precise calibrating and the fixed of the special disk- shape leaf spring, the vibration of the blower is under 15μm.
•Save space: This blower connects with the vertical motor and the inlet and outlet silencers are erect designed, so it is no need to occupy much space to fix the machine.
•Reverse Protected Device: The reverse protected device will prevent the blower damage from motor reversing.
•Self Adjustment of Air Flow: You can choose the unit to adjust the capacity. (Optional accessory)
•Adoption of Full Close Outdoor Motor: Even if the blower is placed outdoors, it won’t suffer from weather. (For blower to be installed in outdoor)
•No need to replace belt permanently: The blower works via coupling rotating directly, so it’s no need to use belt and it will prevent the air pollution from the belt powder.
•No need to fix: The blower is stable with the special anti-vibration device, so it is no need to pipe and the installation is easy.

i, High-pressure Roots Blower Low noise
Quiet type vertical-type 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, Quiet type vertical-type 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 typicalQuiet type vertical-type 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.
