High flow rates even at vacuum levels approaching ultimate vacuum.
High water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast.
Vacuum-tight at switch-off; external anti-suckback valve not needed.
Large oil volume: Long intervals between oil changes.
Ease of maintenance due to telescopic design.
Max. pumping speed at 50/60 Hz: 2.3/2.8 mbar.
Ultimate vacuum (abs.): 2 x 10^-3 mbar.
Inlet connection: Small flange KF DN 16.
