DESCRIPTION
A low speed range and large working
moment are combined in these vibrators to produce
a powerful vibration with a high amplitude.
The body is machined from an aluminium extrusion
which is tempered and hard anodized. It is chemically
resistant and suitable for use in the food and
pharmaceutical industries.
The LP-vibrators (Low Pressure) works most economically
between 30 and 60 PSI while the HP-vibrators (High
Pressure) shows the best results between 60 and
80 PSI. In this range the frequency of vibration
can be varied by regulation of the air pressure,
thus enabling the vibrator to be tuned to suit
the application.
These pneumatic turbine vibrators have a low noise
level. The noise measured in the proximity of
the silencer may be reduced to half when an exhaust
hose is used.

Design
The vibration is produced by the
centrifugal force of the rotor which has a large
excentric moment. The rotor is supported on two
heavy duty bearings which ensure a long working
life even when used at maximum speed.
INSTALLATION INSTRUCTIONS
An air line filter and lubricator
must be used to guarantee a long working life
of the bearings. A hydraulic oil ISO VG5 = 5 cSt/40¢XC
must be used, for example SHELL Tellus Oil C5.
The recommended mounting bolts should be grade
5 or better.
The surface into which the vibrator
is to be mounted should be absolutely flat ¡X mounting
the vibrator to an uneven surface may distort
the vibrator body and cause the turbine to give
less than designed performance. |
