4.2 Description
The V-KTA range has a connecting thread on the pressure side and on the suction side. The aspirated air
is cleaned by an inbuilt fi ne micro fi lter. The carbon dust caused by the scoring of the discs can also 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 compressed air is cooled by
a cooling segment.
The machines are driven by standard fl anged three-phase motors using a coupling.
Pressure and vacuum can be adjusted to the required levels, however, they are limited to a maximum point.
Versions (01) to (30) have cooling exits from two sides whilst versions (31) to (60) have cooling exits on one
side only.
4.3 Areas of application
These dry running rotary vane pressure vacuum pumps models V-KTA 60/1 to V-KTA 140/3 and V-KTA 80/5
are suitable for creating pressure and vacuum at the same time. Constant operation is permissible.
All models have nominal capacities of 60, 80, 100 and 140 m 3 /hr operating at 50 cycles. The pressure and
vacuum limits (bar) are indicated on the data plate (Fig. 2/N). The tables showing capacity against pressure
and vacuum can be seen in data sheets D 452 and D 453.
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-KTA 60 / 80)
resp. 10 times (V-KTA 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).
