4.2 Description
The V-VTA model range has a connecting thread on the suction side and an exhaust silencer on the pressure
side. The aspirated air is cleaned by an inbuilt fi ne micro fi lter. The carbon dust caused by the scoring of the
blades can be separated by an integral fi lter if necessary. A fan between the compressor housing and the
motor provides intensive air cooling. The compressor housing is located in a sound cover.
The machines are driven by standard fl anged three-phase motors using a coupling.
A vacuum regulating valve (Fig. 2/C) is used to set the vacuum to the required values with an upper limit.
Versions (01) to (30) have cooling exits from two sides whilst versions (31) to (60) have cooling exits on one
side only.

Areas of application
These dry running rotary vane vacuum pumps V-VTA 60, V-VTA 80, V-VTA 100 and V-VTA 140 are suitable
for evacuating closed systems and for a permanent vacuum in the intake pressure range 150 - 1000 mbar
(abs.).
The pumping capacity with unrestricted suction is 60, 80, 100 and 140 m
3
/h at 50 Hz. Data sheet D 250
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 12 times (V-VTA 60 / 80)
resp. 10 times (V-VTA 100 / 140) an hour) or at higher ambient temperatures and intake tempera-
tures, 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).
