Instructions

Concise installation and operating instructions for
pneumatic vibrators series NCB, NCR and NCT
S a f e t y
Make sure that the compressed air is
shut off during installation or during
other work on the vibrator and on the
supply lines. Before starting operation
all hoses must be tightly connected.
A hose coming loose under pressure may
cause injury.
Observe the enclosed drawings.
Alterations to the unit may change
the characteristics of the vibrator or
even damage the unit and will cause
the rejection of any warranty claims.
Screw connections must be checked after 1 hour
and then controlled at regular intervals (normally
each month).
Vibrations can cause loosening of bolted connec-
tions and equipment. This may cause damage to
persons and material.
G e n e r a l N o t e s
The vibrators comply with the EC machine
regulation 2006/42/EC.
The standards DIN EN ISO 12100 part 1 and
part 2 particularly have been observed.
The vibrators produce non-directed vibrations.
They are used for emptying bunkers, to drive
chutes, screens and vibrating tables. Generally
for loosening, conveying and separating of bulk
materials and for the reduction of friction.
When observing the operating instructions of
the customer they may also be used in food
processing or wet environments.
The vibrators may be used outdoors.
The frequency and the dependent centrifugal
force are determined by the operating pressure.
Drive medium: Clean, filtered (filter < 5µm),
compressed air or nitrogen of 2 to 6 bar (30 to
90 PSI) is required.
Non-filtered air will damage the vibrators.
The vibrators are designed for
lubrication-free operation. The life
time of NCB and NCR will be
extended with lubrication
Maximum operating pressure: 6 bar (90 PSI).
Noise level: Depending on the type of vibrator
and air pressure the noise level is 75 to 85
dB(A) (with silencer). If the air pressure is
lower, the noise level is also lower. In order to
avoid unnecessary noise, the vibrators should
not be operated without a silencer.
I n s t a l l a t i o n
The unit must be fastened to a
clean and level surface with two
fastening screws (for screw size
and tightening torque see table).
Use self-locking washers (no spring washers).
Use self-locking nuts or e.g. Loctite 270 against
loosening.
It is strongly recommended to use a stiffening
(U-profile) for the substructure. This stiffening
section should be welded to the object. This
allows optimal transfer of the vibration energy.
The air inlet port is smaller than the
outlet port. Both are marked by
arrows on the front.
Supply line: The air resistance increases with
the hose length. The nominal widths in the table
apply for hose lengths of up to 3 m. Longer
supply lines need bigger cross-sections.
Air discharge: If the out flowing air is
discharged and the vibrator should work with
full power, the discharge hose must have a
bigger nominal width than the supply hose.
Rainwater or other fluids must not enter the
housing when using outside. In case of raining
the exhaust air should be discharged down-
wards.
The compressed air supply line must be fas-
tened securely.
Swapping the air inlet and outlet ports will
cause loss in power.
