Recently the move to improve work environments is creating a large demand for quieter vacuum pumps. Developed to meet this demand, the VD series are oil rotary vacuum pumps with low-noise direct-coupled motors. Designed for easy maintenance, the VD series makes daily maintenance and inspection extremely simple.Series models can be used in a wide range of applications
on sites ranging from research labs (where silence is indispensable)to production lines.

[su_tab title=”Features”]

  • Optimized design achieved quiet-running
  • Easy maintenance
  • Forced oil circulation system ensures stable pumping speed
    below atmospheric pressure
  • Totally enclosed fan cooled 3 phase AC motor:
    Multiple voltage motor is equipped on the VD151 and VD201.
    Either 200V class or multiple voltage type is selectable for the VD301 to VD901. 
    All model are complied with high efficiency regulation (GB3/IE2/EPAct)

[su_tab title=”Applications”]

  • Evaporation, sputtering, ion plating
  • Analysis devices, leak test equipment
  • Gas substitution/supply, vacuum insulation
  • Vacuum drying, freeze-drying, vacuum degassing, vacuum packing,
    vacuum chuck, vacuum molding, etc.
