    Advantages

    Ultimate Vacuum
    • Optimized clearance and continuous compression ensures 0.0075torr vacuum degree with a single pump
    Corrosion Resistance
    • Coating material provides excellent corrosion resistance
    • Process specific coatings or platings available
    • Enhanced Corrosion Resistance by the gas ballast
    Cooling Effect
    • Hydrodynamic spiral jacket design ensures Excellent
    • heat exchange efficiency
    • Maintains optimum pump-inside temperature
    Utility Saving
    • 30% power saving by the variable pitch screw design
    • No extra cooling gas required

    Characteristics
