Features
1.Four-point water & air spray – Dual cooling efficiency
The powerful 4-point water spray combined with a 4-point air cooling system effectively maintains the treatment area temperature below 15°C during high-speed operations, preventing discomfort and tissue damage caused by overheating. Compared to traditional single water spray systems, this design improves cooling efficiency by 35%, ensuring each procedure is completed under optimal temperature conditions, significantly enhancing the patient’s treatment experience.
2.Made of stainless steel – High hardness, drop resistant
Constructed with full stainless steel, its impact resistance is increased by 30%, and the lifespan is extended by 1.5 times compared to conventional alloy products. This material is highly resistant to corrosion, maintaining its integrity and smooth surface even after frequent disinfection and high-temperature sterilization. For dental distributors, this means offering a high-quality and durable air-driven turbine, reducing after-sales issues.
3.One-piece molding CNC head – Precison and stability
The CNC precision-machined one-piece head has a roundness tolerance of up to 0.002mm, significantly reducing vibration and the risk of water or air leakage due to head wear. The high precision achieved through this manufacturing process results in improved stability, lowering maintenance costs by 15%, and providing a more comfortable and accurate handling experience for dentists during long procedures.
4.Powerful performacne – Superior cutting force
Equipped with a 20W high-power torque and a rotational speed of 360,000-390,000min-1, it delivers strong cutting force, easily tackling various dental materials. Even when handling hard restorative materials, it performs cutting tasks swiftly. Compared to standard 15W handpieces, this model achieves a 25% increase in cutting speed, saving dentists up to 15 minutes per day, allowing them to serve 120 more patients annually, thereby significantly boosting the clinic’s efficiency.
