Vrn® Wireless Control Ultrasonic Scaler with Auto-water Supply A8 LED Fiber Optic Handpiece

Boost your clinical efficiency with the A8 piezoelectric ultrasonic scaler. Built for precision and reliable performance, it adopts intelligent frequency-tracking technology and supports multiple clinical modes, covering routine scaling, deep periodontal therapy, and root-canal irrigation. It comes with a dual-water-supply system, a detachable LED-equipped autoclavable handpiece, and both wired and wireless foot-pedal options. These practical features simplify your daily workflow while ensuring stable power output, excellent visibility, and improved patient comfort.

 

Features：

1.Intelligent Frequency Tracking Technology：automatically tracks the optimal operating frequency in real-time, maintaining stable output for consistent, efficient calculus removal throughout treatment.

2.Smart Microprocessor Control & Upgraded Piezoelectric Technology: equipped with a built-in intelligent microprocessor chip, the device automatically adjusts power output according to working resistance, enabling smooth operation and effectively preventing tip stalling for enhanced patient comfort. Leveraging advanced piezoelectric ultrasonic vibration, it generates a powerful cavitation effect that efficiently removes dental biofilm and root-canal debris.

3.Three Professional Working Modes:

 ·G Mode (General Scaling): Maximum power output for removing supragingival and interproximal calculus and stains. Compatible with G-series tips (G1, G2, G4).

 ·P Mode (Periodontal): Medium power output optimized for removing subgingival calculus and biofilm within periodontal pockets. Compatible with P-series tips (P1).

 ·E Mode (Endodontic): Low-power ultrasonic activation for root-canal cleaning and irrigation, used together with E1 tip and endodontic files.

4.Detachable High-Brightness LED Handpiece: built-in bright LED lighting illuminates the surgical field, improving visibility inside hard-to-reach oral areas for higher treatment accuracy. Fully detachable for easy maintenance.

5. Antibacterial Internal Water Line: constructed from antimicrobial materials, the internal liquid routing supports safer periodontal and endodontic procedures. Compatible with common clinical solutions such as hydrogen peroxide, chlorhexidine, and sodium hypochlorite to improve disinfection efficacy.

6. Dual Water Supply System：offers flexible clinical operation with support for both a built-in 500ml water bottle and an external water source connection, ensuring uninterrupted treatment efficiency.

7. Wireless & Wired Foot Pedal Control: improve workflow efficiency with remote control options. The system supports both wireless and wired foot pedal modes, allowing you to choose the setup that best fits your operatory layout.

8. Autoclavable Handpiece

Handpiece can be high-temperature-pressure sterilized (135 °C / 0.22 MPa), ensuring strict clinical infection-control requirements.
