2.4.3 Portfolio overview
Pfeiffer Vacuum offers two piston vacuum pumps, the single-stage XtraDry 250-1 and the two-stage XtraDry 150-2. These pumps differ in terms of their pumping speeds and ultimate pressures. In particular, the two-stage XtraDry is characterized by:
- Low base pressure: pb = 0.1 mbar
- Gas ballast
- Automatic speed reduction near base pressure
