Note:
This specification uses SI measurement units. Conversion to non-SI units is as follows :
Final pressure : 2.7 Pa = 2 x 10-2 torr; Water pressure: 0.3 MPa = 3 kg/cm2
*1 Measured by Pirani vacuum gauge (Approx. 1.5Pa when measured with a McLeod vacuum gauge)
*2 When ordering, specify whether you require a motor, and if you do, specify its type, voltage and frequency. Totally enclosed fan-cooled flange motors, increased safety flange motors, and explosion-proof flange motors are available as options.
*3 Other oil types are available. Contact ULVAC’s Sales Department.
