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°C 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 — mounting the vibrator to an uneven surface may distort the vibrator body and cause the turbine to give less than designed performance.
