(Type of backing pump look at max. pumping speed). When using 2-stage backing pumps the ultimate pressures will be
correspondingly lower.
3) Applicable for ratio up to 1 : 10 between backing pump and Roots vacuum pump at 3000 rpm

Authoriative, however, is the oil level at the oil-level glass
5)
After a complete disassembly
6) At an operating pressure below < 10 -1 mbar (< 0.75 x 10 -1 Torr)
8) Motor voltage and current may deviate depending on the type of motor.
Please always note the information on the nameplate.
