Series PRV Pneumatic Roller Vibrators have a high vibration frequency feature that
can prevent mater ial jams in pipe delivery. It can also be applied for bridge-break or
concrete injection operation conditions. The special aluminum body is equipped with a
roller and ring with multi-nozzles. It is tightly closed by plastic side covers. Vibration is
caused when the roller pushed by compressed air runs in a rotary motion to produce
centrifugal force.
