The V-DTN range has a connecting thread on the pressure side and a silencer 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 compressor is in a plastic sound cover. Inside the sound cover is
also a fan that cools the V-DTN. The compressed air in sizes 15, 25 and 40 is cooled by a cooling segment
with a greater motor output.
The pressure regulating valve (Fig. 2/D) is used to set the pressure to the required values with an upper limit.
4.3. Areas of application
These dry running rotary vane compressors, V-DTN 6 to V-DTN 40, are suitable for creating excess pressure
between 0 and the maximum limit (in bars) given on the data plate (Fig. 2/N). Constant operation is permissible.
The compressors have a nominal fl ow rate of 6, 10, 15, 25 and 40 m
3
/h at 50 Hz. The load limits (bars) on the
pressure side are given on the data plate (N). Data sheet D 380 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 follow-
ing 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 compressor volume fl ow is reduced if the
pressure pipe is too narrow and/or too long.
b) Check to ensure the pressure line is 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 valve
The required pressure ranges can be set with the
pressure regulating valve (Fig. 2/D) as shown on the
symbol plate affi xed to the rotary knob.
NOTICE
Do not operate without the standard control
and relief valve.
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 must only be done by a
qualifi ed 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 the plug connection or
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 may occur when
the machine is started cold.
NOTICE
Power supply
The conditions at the installation location must match
the information on the motor data plate. Without
derating the following is permissible:
May lead to severe or fatal injuries. Therefore be
sure to obey the safety instructions.
CAUTION
Noise emission
The highest noise pressure levels measured as
per EN ISO 3744 are given in Section 9.
When spending a long time in the vicinity of the
running machine use ear protectors to avoid permanent damage to your hearing.
NOTICE
Wait until the machine stops
The machine must only be switched on again
after it stops.
check the direction of rotation. When looking at
the motor fan, it must rotate clockwise.
The pressure pipe must not be connected
when starting up like this.
NOTICE
Incorrect direction of rotation
Running the machine in reverse for a long time may
cause damage to the blades which may lead to the
blades breaking. Use a phase sequence indicator
to check the direction of rotation (anti-clockwise
rotating fi eld).
6.2 Decommissioning/ storing
Stop the machine
a) Switch the machine off.
b) If available close the cut off device in the suction
and pressure pipe.
c) Disconnect the machine from the electricity
source.
d) Depressurise the machine: Open the pipes
slowly.
The pressure reduces slowly.
e) Remove the pipes and hoses.
f) Seal the connections for suction and discharge
nozzles with adhesive foil.

seated properly and if necessary seal again or tighten up.
monthlyCheck the terminal box and cable inlet holes for leaks and if
—
necessary re-seal.
monthlyClean the regulating valve and ventilation slots on the machi-
—
ne and the motor cooling ribs.
If there is a great deal of dust in the spaces on the cooling
ribs and cooling pipes after removing the inlet grating (Fig. 2/
G) clean by blowing through.
—
The machine‘s bearings are permanently lubricated and do
—
not require re-lubricating.
monthly / every 6 monthsClean or replace fi lter cartridges7.2.1
The power of the machine lessens and damage may
occur to the machine.
The fi lter cartridges for incoming air (Fig. 4/e) and
blowing air (Fig. 4/f ➝ accessory) must be cleaned
by blowing through from the inside out once a
month or more often depending on the level of contamination. In spite of cleaning the filters their separation efficiency will continue to deteriorate. Therefore the fi lters should be replaced every six months.
Changing fi lters:
Unscrew the outlet grid (Fig. 4/G). Undo the screw
cap (Fig. 4/s) and the knurled knob (Fig. 4/m). Remove and clean or replace fi lter cartridges (e) and (f).
Reassemble in reverse order.
