VIBCO Model CCF-5000 Silent Pneumatic Turbine Vibrators were installed to replace the noisy piston vibrators. Designed with graphite bearings, the VIBCO CCF-5000s can withstand high heat environments. They are also pre-lubricated for life, so the customer no longer had to deal with a difficult maintenance issue. The special mounting plate designed by VIBCO engineers for high temperature environments increased the effectiveness and longevity of the vibrators.
