  • W&H - Primea Advanced Air turbine

    With the Primea Advanced Air you can perform this sensitive step with a constantly low bur speed of just 60,000 rpm. This allows you to profile the preparation surface even more minimally invasively and finish the preparation margins with even more control than with a classic turbine handpiece.

  • Characterizing the performance of dental air-turbine ...

    2008-1-1 · In general, flow is unaffected by handpiece load (i.e. turbine speed) and, in most cases, it is essentially unaffected by stalling the rotor. In a few cases, a small reduction (0.1–0.3 L/min) occurs in specific rotor positions (i.e. with a rotor blade adjacent to the supply nozzle, effectively blocking it), although slow rotation (>1/s) causes the effect to become undetectable and thus of …

  • W&H - Dental Handpieces - What should you look for

    With turbines the bur is directly driven by a rotor. The rotor has an impeller powered by compressed air. Turbines reach an idle speed of up to 400,000 min-1. The working speed depends on the pressure exerted and is approximately half the idle speed - i.e. approx. 150,000 to 250,000 min-1. The maximum power of 10-26 W is also reached in this speed range.
