The Silent Power Turbines are powerful yet remarkably silent instruments for Dentists. It has multiple irrigation with separate nozzles, a click-wheel control for per irrigation flow adjustment, LED lighting and a button-operated release for bur change. Thanks to cutting-edge ball bearing technology, precise rotation and study of fluid-dynamic airflows, turbine noise emissions have been more than halved and contained within an average of 57 dB(A), which is imperceptible against normal background noise. The two separate nozzles, one for water and one for air at each irrigation point ensure that fluids are not mixed inside the turbine and prevent cross-contamination of circuits. Two and four spray irrigators in between ensure optimal cooling and maximum visibility within the operating area whatever the treatment scenario.
