Rotary Pneumatic Ring Vibrators DR Series offer superior performance in applications where ball vibrators don't last. Because of their unique yet simple design the Rotary Pneumatic Ring Vibrators give years of trouble free efficient operation. They are maintenance free and require no lubrication.
Rotary Pneumatic Ring Vibrators DR Series generate very high frequencies and centrifugal forces with low air consumption. The high centrifugal forces and frequencies are generated by a high strength alloy steel ring which makes an eccentric movement around a hardened alloy steel center post. This design eliminates accumulated build up from air particles where other vibrators would clog or stop running. The Rotary Pneumatic Ring Vibrators DR Series are used as flow aid devices on bins and hoppers to avoid bridging or rat holing, as well as for screening, compacting, molding dies, and for sorting and separation.

The DR series vibrators offer low cost operation for those who have been disappointed with a ball vibrator performance in the past.
