The compact pneumatic vibrators

These compact pneumatic vibrators are simple in design and yet capable of deliverieng very high centrifugal forces. The body is machined from an extruded aluminium section, inside of which a precision steel roller rotates, it is retained by two special high impact plastic end plates. For easy mounting, the body has four holes, two horizontal and two vertical. Air is introduced through one of two inlet ports drilled at right angles to each other in the body. These inlet ports are tapped with a standard polyurethane pipe thread and a pipe plug is provided for sealing the one not used. The air is exhausted through the special high impact plastic end plates whose design incorporates an air silencer.
