Advantage of 3 lobes' rotor design

Owing to new 3 lobes' rotor design , 
the reverse flow pressure variation period is only 2/3 of that of a conventional 2 lobes' rotor, the peak pressure is also lower. So the noise and pressure pulsation are greatly limited.
  • Less back flow, steady air flow rate, lower vibration and noise.
  • Discharge pressure pulsation are reduced, so lighter loading of bearings and timing gears ensures the long servicing life.
  • Adequate clearance between the rotors and the rotors with the casing ensure no contact during operation, and this make the efficiency even higher.
  • The rotors are dynamically balanced in the fabrication stage already, so these rotor are almost free from vibration.
