Oil Rotary Vacuum Pump
- High efficiency (IE3) multiple voltage motor fully developed by ULVAC
A single motor can cover a wide range voltage, 200 to 240V / 380 to 460V.
- Forced oil circulation system
Pumping speed is stable even around atmospheric pressure. It is suitable for repeat and continuous running between atmospheric pressure and vacuum.
- Various options are available for special application
3 types, type A, B and H, are available in addition to standard type for special application.
- Evaporation, sputtering, and ion plating
- Analytical instrument and leak test system
- Gas exchange, liquid filling
- Vacuum dry, freeze dry, vacuum deaeration, and vacuum insulation
- Vacuum chuck and vacuum molding
- Other vacuum equipments
