4.2 Description
The V-VTN model range has a connecting thread on the suction side and an exhaust silencer on the pres-
sure side. The aspirated air is cleaned by an inbuilt fi ne micro fi lter.
The motor and the pump have a common shaft.
The vacuum pumps V-VTN are located in a plastic sound cover.
Inside the sound cover is also a fan that
provides cooling.
The V-VTN (02) has a vacuum regulating valve fi tted as standard (Fig. 2/C) that enables the vacuum to be set
to the required values which have an upper limit.
4.3 Areas of application
These dry running rotary vane vacuum pumps V-VTN 16 to V-VTN 41 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 15, 25 and 40 m 3 /h at 50 Hz. Data sheet D 281 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).
