The long service life of our vibrators is because they are manufactured with the highest quality construction materials, specially designed oversized bearings using Kluber lubrication to prevent wear and damage, minimize noise and reduce operating and maintenance costs. In addition, our rotary vibrators provide the lowest noise level in the industry – typical noise level averages 60 dbA at 4'. For assistance in choosing the ideal model, size, and mounting location for your application, give us a call - we'll handle it from there with GUARANTEED results!
