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 (01 ➝ 06) and (08 ➝ 10) 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 pressure to be set to the required values which have an upper limit.
The compressed air is cooled by a cooling segment in versions (03), (06), (09) and (10).
The V-KTN (13) is located in a tin cover. It is cooled by the motor fan. The V-KTN (13) has a vacuum safety
valve on the suction side (Fig. 3/C
) and a pressure relief valve on the pressure side (Fig. 3/D1).

4.3. Areas of application
These dry running rotary vane pressure vacuum pumps models V-KTN 15 to V-KTN 40 are suitable for creating 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 480 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).
• Suffi cient room for installing and removing pipes
and for maintenance work, particularly for installing and dismantling the machine
• No external vibration effects
• Do not suck any hot exhaust air from other machines into the cooling system.
To remove the outlet grid (Fig. 2/G), the inlet grating (Fig. 2/G
) and the housing lid (b) at least
1
30 cm of space must be available for maintenance work. You must also ensure that the cooling air
inlets (Fig. 2/E) and cooling air outlets (Fig. 2/F) must be at least 10 cm away from the nearest wall
(outgoing cooling air must not be sucked in again).
5.2 Installation
NOTICE
The machine may only be operated when it is
set up horizontally.
Material damage resulting from the machine
tipping over and falling.
When installed at more than 1000 m above sea
level a reduction in power is noticeable. In this
case we would ask you to contact us.
Ensure that the foundation complies with the following conditions:
• Level and straight
• The bearing surface must be able to bear the
weight of the machine
It must be possible to install the machine on a fi rm foundation without anchoring. When installing
on a substructure we recommend fi xing with fl exible buffers.
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
screw pipes in by hand.
The machine output is reduced if the pipes are
too narrow and/or too long.
b) Check to ensure the intake line and pressure line
are connected correctly.
NOTICE
Length of the connection pipes
With connection pipes that have the same pipe
cross section as the machine connection and are
more than 3m long, a non-return valve especially
for the purpose must be installed in order to avoid
reverse operation when the machine has stopped
5.4 Control and relief valves
The required pressure and vacuum ranges can be
set with the pressure regulating valve (Fig. 2/D) and
the vacuum regulating valve (Fig. 2/C) as shown on
the symbol plate attached to the rotary knob.
NOTICE
Do not operate without the standard control
and relief valves.
If the permissible fi nal compression pressure is
exceeded (see data plate) the machine may be
damaged.
Danger of death if the electrical installation has
not been done professionally.
The electrical installation may only be done by a specialist electrician observing EN 60204. The operating
company has to provide the main switch.
a) The electrical motor data can be found on the
data plate (Fig. 2/N) or the motor data plate. The
motors comply with DIN EN 60034 and are in
protection class IP 55 and insulation class F. The
appropriate connection diagram is located in the
motor‘s terminal box (not for the plug connection version). The motor data must be compared
with the data of the existing mains network (current type, voltage, network frequency, permitted
current value).
b) Connect the motor via plug-connector (Fig. 2/J)
if fi tted or via the motor protection switch (for
safety reasons, a motor protection switch is
required and the connecting cable must be installed via a cable fi tting to provide strain relief).
We recommend using motor protection switches
with delayed switch off, depending on possible
excess current. Temporary excess current can
occur when the machine is started cold.
NOTICE
