DIS/DISL scroll vacuum pump is a double wrap type which consists of 1 orbiting and 2 fixed scrolls. Operation from atmospheric pressure is possible. High ultimate pressure level is attainable. Low vibration and noise. Maintenance cycle can be controlled by hour meter.


  • Compact size with large displacement.
  • The highest level of ultimate pressure for dry vacuum pumps.
  • Safety design with built-in automatic reset type thermal protector.
  • Suppresses moisture condensation by air flush.


  • Analytical equipment.
  • Gas recovery system.
  • Coating equipment.
  • Back pump for TMP.
  • Helium leak detector.
  • Manufacturing process for semiconductor.


※1:Actual pumping speed is about 1.2 times the Actual pumping speed when a gas at atmospheric pressure is sucked.
※2:Power supply plug and Power supply code are not included.
※3:AF=Air flush 
The air flush operation not only discharges the water remaining in the pump, but also has the effect of recovering the Ultimate pressure.
