Edwards XDS35i – dry scroll vacuum pump with 35 m³/h
The XDS35i is a hermetically sealed, dry scroll pump with a pumping speed of 35 m³/h and an ultimate pressure of 0.01 mbar. The Enhanced version (E) has bypass valves: it pumps down from atmospheric pressure continuously at full speed, whereas the intelligent control of the standard version reduces power and speed after a short period of peak power.Versions
