advantage of RH roots blower

Advantagesof RH roots blower:

1. The inlet of RH roots blower adopts a spiral type. When the impeller is rotating, the top boss is cut into the casing through a spiral line to form a cavity that opens and closes sequentially, thereby reducing the pulsation of the blower.

2.  The rotor adopts a more advanced profile,the volumetric efficiency is increased by 5% to 8% when the pressure is boosted to 98kPa, and the noise is reduced by about 5dB (A).

3. The rotors are all produced by precision CNC special equipment (CNC bidirectional curved surface planer), and are quality-checked by the three-coordinate measuring center, so there is no performance error between each blower. The rotor part undergoes dynamic and static balance tests before assembly, thus the vibration is extremely small.

4. High-precision grinding gears are used to reduce mechanical noise. The gear accuracy is level 5 required by the national standard GB/T 10095-2008.

5. The new fully enclosed oil tank and lubrication system ensure that the fan does not spray or leak oil, and eliminate the on-site pollution caused by the oil injection and oil leakage of the old Roots blower
