- 1) To DIN 28 400 and subsequent numbers
- 2) With double-stage rotary vane vacuum pump TRIVAC, resp. single-stage rotary vane vacuum pump SOGEVAC (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
- 4) Authoriative, however, is the oil level at the oil-level glass
- 5) After a complete disassembly
- 6) US models ANSI flanges
- 7) At an operating pressure below < 10-1 mbar (< 0.75 x 10-1 Torr)
