These roller and turbine rotary vibrators produce an omnidirectional centrifugal force at a speed and amplitude that enable them to transmit energy waves over a large surface area. This power, when combined with their quick-change cradle lug mount, means that each job requires fewer vibrators and less manpower to provide ideal consolidation and surface finish. Add the low maintenance because of their simple, yet rugged, design, and you have an ROI investment solution that can’t be beat. These vibrators usually operate at speeds (frequencies) of 6,000 to 12,000 vibrations per minute (VPM) based on the model selected and the air pressure, and volume supplied.
