Premium 700S non-optic high-speed air-turbine with hygiene head
Premium 700S non-optic high-speed air-turbine with hygiene head-QD
The Premium 700S is a non-optic high-speed air-turbine designed for daily restorative preparation, featuring high-torque, low-noise operation and a hygiene-focused, anti-retraction sealed head that helps block oral fluids from entering the head and tubing. A single water spray reduces water block issues, while thoughtful air exhaust control maintains speed even when input pressure is high.

Why Choose Premium 700S (Comfort, Hygiene, Uptime)

  • Ergonomics & visibility: Standard head (Ø12.5 × H13.2 mm) for comfort and precise results.

  • Anti-retraction sealed head: Combined with a non-return valve to help prevent intraoral fluid ingress—supports hygiene and bearing life.

  • Fewer spray stoppages: The single water spray design helps reduce water blockage issues.

Performance & Handling (High-Torque, Low Noise, Speed Control)

  • High-speed range: 320,000–380,000 min⁻¹ idle. Quick bur stop (~2–3 s).

  • Whisper-quiet: ≤57 dB(A) to improve the patient and operator experience.

  • Overspeed protection: Self-venting governor bleeds excess pressure to hold max speed at 380,000 min⁻¹.
     

Specifications & Connections

  • Head/Chuck: Push-button chuck; robust system up to 30 N holding force; FG Ø1.6 mm burs (short-shank up to 21 mm).

  • Bearings & longevity: Premium ceramic bearings, precision balancing, heat-treated spindles, EDM collet, stainless bur guide bushing for concentricity, and extended chuck life.

  • Backends: Fixed M4 (4-hole) or B2 (2-hole), or swivel connection (NSK® QDJ-type).

Sterilization & Maintenance
