RW type: WATER-JACKET TO PASS THROUGH GEARBOX AND BEARINGS FOR COOLING.

We produce robust, heavy-duty tri-lobe designs roots blower (2″ – 12″) that deliver reliable performance for low noise, low pulsation compression.

CHARACTERISTICS

  • Produce a constant flow of gas at different pressures.

  • No Contamination: The pumped gas does not get contaminated as there are no lubricants in the area where the compression occurs.

  • Gear Box, Front Bearing and Rear Bearing: Oil Lubrication and Water-Jacket Cooling Feature.

  • Front Bearing: Grease Lubrication and Water-Jacket Cooling Feature

ADVANTAGE OF TRI-LOBE' ROTOR DESIGN

Owing to the new tri-lobe’ rotor design in our roots blower, the reverse flow pressure variation period is only 2/3 of that of a conventional bi-lobe’ rotor, the peak pressure is also lower. So the noise and pressure pulsation is greatly limited.
  • Less backflow, steady air flow rate, lower vibration, and noise.

  • Long Servicing Life: With reduced discharged pressure pulsation, it leads to lighter loading of bearings and timing gears for longer operation life.

  • Large Air Flow: On the same operating speed, the tri-lobe roots blower can deliver large airflow and volume than the conventional 2 lobes type.

  • High Efficiency: Adequate clearance between the rotors and the casing ensures no contact during operation, and this makes even higher efficiency.

  • High Precision in rotors: The precision of rotors is fully controlled by the CNC machine and variation of precision between blowers is almost nil.

  • Free From Vibration: The rotors are dynamically balanced in the fabrication stage already, so rotors are almost free from vibration.
