4.2 Description
The V-VTE model range are complete with a pipe connection on the inlet and an exhaust silencer on the outlet.
All the air handled is fi ltered by a built-in micro-fi ne fi lter. The motor fan cools the motor and pump housing.
Both the motor and pump have a common shaft.
4.3 Areas of application
These dry running rotary vane vacuum pumps V-VTE 3 to V-VTE 10 are suitable for evacuating closed sys-
tems and for a permanent vacuum in the intake pressure range 150 - 1000 mbars (abs.).
The pumping capacity with unrestricted suction is 3.5, 6, 8 and 10 m 3 /h at 50 Hz. Data sheet D 187 shows
the dependency of the pumping capacity on the intake pressure.
These dry running machines are suitable for conveying air with a relative humidity of 30 - 90 %.
If the unit is switched on more frequently (at regular intervals of about 10 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 in the open air the unit must be protected from environmental infl uences, (e.g. by a
protective roof).
