Set up and operation

4.3 Areas of application

The VSI pumps are suitable for the evacuation of closed volumes for a continuous vacuum within a pressure
range of: 0.075 to 760 Torr.
They are also suitable for handling humid gas streams due to its high water vapor tolerance.
The maximum pumping capacity is 224 cfm at 60 Hz. Data sheet D832-44-US shows the vacuum versus
capacity performance curve.

If the unit is switched on more frequently (at regular
intervals of > 8 times an hour) or at higher ambient
temperatures and intake temperatures, the excess
temperature limit of the motor winding and the
bearings may be exceeded. Please contact the
manufacturer should the unit be used under such
conditions.
If it is installed outdoors, the pump must be
protected from environmental influences, (e.g. by a
protective roof).
