R Series Pneumatic Roller Vibrators are durable, compact, lightweight, and simple in design, and are capable of delivering very high centrifugal forces.  R Series construction features a lightweight machined aluminum body, precision steel roller, and special high impact plastic endplates. For easy mounting, the body has two sets of mounting holes*; one set for horizontal mounting, the other for vertical mounting. Air is supplied to the unit through one of two inlet ports, which are drilled at right angles to one another in the body. This design feature allows easy access to air inlets in various mounting positions. Inlet ports are tapped with a standard pipe thread, and a pipe plug is provided for sealing the unused inlet. Air is exhausted through an air silencer incorporated into the design of the end plates.  R Series Vibrators provide a new approach to the movement of fine materials, and are ideal for many applications, including emptying hoppers, agitating small particles, moving fine powders, and compacting plastic and concrete in molds.
