4.2 Description
The V-KTN 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 blades can also be
separated by an integral fi lter.
The motor and the pump have a common shaft.
The V-KTN are in a plastic sound cover. Inside the sound cover is also a fan that provides cooling. The
vacuum regulating valve (Fig. 2/C) and the pressure regulating valve (Fig. 2/D) enable the vacuum and pres-
sure to be set to the required values which have an upper limit.
The compressed air is cooled by a cooling segment in versions (02) and (03).
4.3. Areas of application
These dry running rotary vane pressure vacuum pumps models V-KTN 16 to V-KTN 41 are suitable for creat-
ing pressure and vacuum at the same time. Constant operation is permissible.
The nominal fl ow rate is 15, 25 and 40 m 3 /h at 50 Hz. The load limits (bars) on the intake and pressure sides
are specifi ed on the data plate (Fig. 2/N). Data sheet D 481 shows the dependency of the fl ow rate on the
excess pressures.
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).
