4.2 Description
The V-KTA /4 range has two connecting threads on the suction side and one 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 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 60/4 to V-KTA 140/4 are suitable for
creating pressure and two different vacuum levels 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).
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).
