Screw Type Dry Vacuum Pump

LS Series



High pumping speed and Low power consumption. Model is selectable with the optimum pumping speed according to the application.


  • High pumping speed at near atmospheric pressure, and pumping down time can be drastically reduced
  • ECO-SHOCK technology realizes low power consumption. (C Type)
     Power consumption at the ultimate pressure is the industry-leading 0.6kW or less.(LS120A-C)
  • Built-in silencer achieves the noise level 61dB(A) or less.
  • Low running-cost
     No shaft sealing gas.
     ※Purge gas is available with L Type.
  • 4 Pumping speed120~1200m3/h Class ※With mecanical booster pump
     Model is selectable with the optimum pumping speed according to the application.
