Simplest of all rotary models with air pressure forcing a ball to rotate around a hardened steel race.
Body in aluminium or cast steel.
Force outputs from 50 to 6381 newtons.
Low first cost, but can be noisy and not very air efficient.
USE for dry materials.
Ball is replaced by roller to give more rotating mass.
Body in aluminium or cast steel.
Force outputs from 490 to 14130 newtons.
More efficient than ball but can still be noisy and air hungry.
USE for dry material.
Out of balance turbine is held in bearings at each end of the shaft to give the most efficient rotary vibrator.
Body in aluminium.
Force outputs from 294 to 8348 newtons.
Very quiet and air efficient.
USE for dry materials.
