Multi-Stage Roots Type Dry Vacuum Pump

LR Series

LR

アルバック

Uniformity of low temperature distribution. The optimum pump for the evacuation of LL chamber, in addition to the PVD processes, in which reduction of exhaust time is important to up the throughput.

Features

  • 'Low temparature pump(LR series)
    'The LR series pump is designed to shorten the pumping time for load lock, PVD processes and etc.
  • Excellent helium pumping capability
    Canned motor for safety and ease of maintenance
  • Power failure protection
    Pump withstands power interruptions of up to 500ms duration.
  • Superior resistance for corrosive gas(HR/UR series)
    Internal components are specially treated providing a high degree of surface hardness and corrosion resistance. This prevents wear and corrosion of internal pump parts when exposed to corrosive gasses.
  • Communication function
    Pump data including warnings and alarms are able to be exported. Extensive pump control is available.

Applications

  • Sputtering equipment、Vapor deposition equipment、etc.
  • Shorten the pumping time of load lock chamber
  • Backing pump for turbo-molecular pumps and mechanical booster pumps
