2 Safety The NTK are intended for generating linear vibrations.
General applications are: loosening, conveying, sorting, compacting, sepa-
rating bulk materials and reducing friction. NTK are used for emptying
bunkers, as drives for conveyor troughs, sieves and vibrating tables.
The NTK are designed for installation in machines and may only be put
into operation, if it has been assured that the complete machine complies
with the regulations of the machinery directive.
The NTK may also be used outdoors and in dusty and humid environ-
ments. The NTK may not be submerged in bulk materials or in liquids.
Any other use is considered improper.
Installation, commissioning, maintenance and troubleshooting of the NTK
may only be performed by authorised qualified personnel.
All handling of the NTK is the responsibility of the operator.
WARNING
Falling parts
The NTK, construction parts as well as fastening screws can
come loose due to vibration. Falling parts lead to severe
personal injuries.
➢For mounting the NTK use only suitable fastening
screws.
➢Use only self-locking washers, self-locking nuts or suita-
ble screw safety agent to secure the NTK.
➢Check the fastening screws after one hour of operation
and thereafter at regular intervals (generally monthly).
➢If necessary, tighten the fastening screws with a torque
wrench.
➢Appropriate safety measures are compulsory for critical
installation situations.

WARNING
Compressed air
A loosened hose which is under pressure can lead to personal injuries.
➢Screw the hose lines on carefully.
➢Check the hose lines and connections after one hour of operation and
thereafter regularly (generally monthly).
➢Retighten the hose lines, if necessary.
➢Ensure that the compressed air is disconnected from the supply lines
during all work on the NTK.
➢Prevent the NTK from being switched back on during all work.
WARNING
Moving parts
NTK have moving parts which can cause injury.
➢The direct contact of a vibrating part must be prevented on site by con-
structive measures, eg. by a screen.
NOTICE
Operation of the NTK with silencers is mandatory.
Silencers reduce the noise level and protect the NTK from contamination
entering.

These data are comparative values and can vary depending on the application. Further data on request.
By changing the weight of the freely oscillating part (e.g. by attaching an
additional oscillating weight to the piston or housing), the oscillation band-
width and the unbalance change. This means that by selecting the freely
oscillating part, the unbalance can be preselected.

Chamber B
The NTK generate linear vibrations.
The vibration is generated by a freely oscillating, self-reversing piston.
Both weights, the piston (5) with an additional oscillating weight (6) on the
one hand, the housing (2) and the weight to which it is attached on the
other, oscillate in relation to their total weights against each other. If the
vibration amplitude of the weight to be vibrated should be higher, then a
larger additional oscillating weight (6) is simply screwed to the piston (5).
To keep the weight to be vibrated low, the piston can be connected to it (in
the case of steel housings), in which case the housing (2) oscillates freely,
if necessary with an additional oscillating weight.
The compressed air enters chamber A via the air inlet (3). The piston is
pressed by the air in the direction of the cover (1). When the piston ex-
ceeds a defined position, then compressed air reaches chamber B via
control bores in the piston. As the piston surface of chamber B is greater
than that of chamber A, the piston is pressed in the opposite direction.
When another control bore reaches the air outlet (4), then chamber B is
vented and the process begins again.
As the piston always reverses again before the end stop, the exhaust air
only produces a slight noise, which is minimized by a silencer (4).

5 Transport and storage
Special conditions of transport are not required.
Use suitable lifting equipment to move the NTK 85 E and the NTK 110 E.
A transport lug can be screwed into
the piston or into the housing (M 20
thread) when lifting.
Note:The piston moves out of the
housing when lifted and into the
housing when lowered.
Be careful
when lifting and lowering
The NTK are packed and ready for assembly. Accessories and add-on
parts are delivered unmounted, unless otherwise agreed upon.
The packaging protects the NTK from transport damage. The packaging
material has been selected from an environmentally safe and technically
disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and
reduces the amount of waste.
•Store the NTK in a dry and clean environment.
•Protect the NTK from UV-exposures, weather and ozone.
•The storage temperature is between -20 °C and +60 °C.
•Close all openings when re-storing.
•Preserve the NTK with steel housing before storing:
1. Put anti-corrosion oil into the air in- and outlet of the NTK.
2. Pull the piston of the NTK in and out while turning it several times.
3. Close the air supply connections of the NTK.

NTK
Special circuit diagrams are available on request.
Information regarding tightening torques for screws as well as cross sec-
tions for valves and hoses can be found in Ch. Technical data, page 7.
When installing the NTK, carry out the following steps in succession:
1. Notice: The NTK must rest fully so that no tension in the housing oc-
curs when tightening the fastening screw, which could cause mechan-
ical damage. Mount the NTK with the central fastening screw and a
suitable lock washer on a clean and even surface (±0,1 mm flatness)
without any paint residues or burn-ins.
Depending on the intended use, NTK can be screwed on either with
the housing or with the piston.
Types from size NTK 55 E up have additional
mounting holes (4) in the housing.
If necessary, use all additional mounting holes
and the corresponding number of lock washers
to additionally secure the housing to the mass
to be vibrated.

2. Observe the recommended values for screw sizes and tightening tor-
ques.
3. In addition, use a medium-strength liquid safety agent to secure the
screw connections.
4. Observe the recommended cross-sections for valves and hoses. For
the air supply, preferably use screw connections with integrated seals

or liquid sealant. Notice: Do not use sealing tape for the screw con-
nections. Do not use longer screw threads for the air supply than in-
tended (e.g. no pipes with external thread). Otherwise, the housing
may become deformed and the piston may jam.
5. Fasten the compressed air supply securely.
6. Mount the silencer/silencers.
The loss of pressure increases with hose length. The nominal diameters in
Ch. Technical data, from page 7 on, apply to hose lengths up to 3 m.
Longer supply lines require larger cross-sections.
If necessary, the escaping air is diverted through a hose, which must be
installed as follows:
1. Remove the silencer.
2. Fasten the exhaust air hose directly to the exhaust air connection.
3. Mount the silencer at the free end of the exhaust hose.
If the NTK is to achieve full performance, then the exhaust hose must have
a larger nominal size than the supply hose.
Notice: In dusty environment or with oil-free operation the NTK must be
operated with bellows or other suitable dust protection.
How to assemble the optional Netter bellows NFB:
1. Clean (degrease) the contact surfaces on the NTK and on the addi-
tional oscillating weight.
2. Remove the protective foil from an adhesive surface on the bellows.
3. Slide the bellows over the piston and glue the bellows to the body of
the NTK.
4. Hold the piston by the wrench flats with a wrench. Attach the addition-
al oscillating weight to the piston with a screw with a medium-strength
screw locking agent. If no additional oscillating weight is used with
freely oscillating piston, a sheet metal disk with the diameter of the vi-
brator housing must be screwed onto the piston.
5. Remove the protective film from the free adhesive surface of the bel-
lows and press the adhesive surface onto the additional oscillating
weight or the sheet metal disc.
With the easy-to-release Velcro fasteners on the bellows, the wrench flats
on the piston remain accessible.

Using the NTK as impactor is possible.
A prior consultation with Netter Vibration is recommended.
The piston must strike against a surface
standing vertically to the NTK.
For this application lubricated com-
pressed air is mandatory.
Warning: NTK have moving parts which can cause injuries. Direct contact
with an oscillating part must be prevented on site by structural measures,
for example by shielding.
For the NTK 8 AL type a cover sleeve can be supplied.

7 Start-up and operation
Observe the safety instructions in chap. Safety, from page 5 on.
Please refer to chap. Technical data, page 7 for permissible operating
conditions.
The frequency of the NTK should be set with the pressure regulator of the
maintenance unit.
The frequency is reduced by lowering the air pressure before the NTK.
The centrifugal force is hereby also reduced. At the same time the ampli-
tude remains almost constant.
If required, install a throttle valve in the exhaust air line in order to adjust
the amplitude of the NTK by throttling the exhaust air. By throttling the ex-
haust air, the centrifugal force is reduced. The frequency hereby remains
almost constant.
Important: Reduced cross-sections already throttle (observe the nominal
diameter).
Reduce the amplitude only up to approx. 50 %. This can cause start-up
problems if below.
Depending on the vibration mass attached to the piston, the amplitude and
frequency change.
A smaller vibration mass increases the frequency and reduces the ampli-
tude. A larger vibration mass increases the amplitude and reduces the fre-
quency.
Set the mist lubricator to the smallest safely adjustable number of drops
while the NTK is running. Notice: The NTK is ready for operation only af-
ter adjustment and correct functioning of the mist lubricator.
Netter Vibration recommends setting the following number of drops, de-
pending on the type of NTK, on the mist lubricators:
NTK
Number of drops
8 AL, 15 X, 16, 18 AL, 18 AL M1, 25, 25 AL, 28 AL
1-2 drops/min
