R7-Water-Air Separation Turbine
The Air R7 is a high-performance water-air separation turbine featuring a 4-point water spray system, stainless steel construction, and clean head system.
Model: R7. Extremely Durable, Low Maintenance.
The R7 Water-Air Separation Turbine is designed to improve airflow stability and spray performance during dental procedures. By separating water and air more efficiently, the handpiece delivers smoother cutting, more stable rotation, and improved cooling performance during long treatments.
Compared with ordinary turbines, the R7 minimizes nose‑tip deformation resulting from frequent accidental drops. This safeguards internal head components, enhances operational stability, and prolongs the service life of internal parts. Tailored specifically for dentists, it meets daily clinical demands for impact resistance, long‑term durability, and consistent cutting performance.
The R7 Dental Turbine is recommended for:
- Student dentists needing durable and affordable turbines for practice
- Clinics upgrading atomization effect due to insufficient water pressure
- Dental distributors seeking the lower maintenance and affordable turbines
- OEM brands/private-label partners needing to expand their brands
- Markets requiring stainless steel material and 4 water sprays turbines
Why Water-Air Separation Matters？
Equipped with an advanced water‑air separation structure, the R7 effectively isolates atomized water vapor within the turbine head and optimizes internal airflow distribution.
Key performance benefits include:
- Resolving uneven water or air flow when the pressure is unstable
- Resolving blurred clinical vision and excessive water spray
- More stable rotational speed and greater torque
- Enhanced cutting precision and operational consistency
- Effective corrosion‑proof protection for precision internal bearings
- Minimized internal humidity accumulation and microbial residue risks
- Sustained smooth long‑term performance with reduced wear‑and‑tear
This design is especially suitable for clinics with high daily treatment frequency.

Designed for New Dentists and Durable Clinical Performance
100° Angled Head, Ergonomic Design
Considering the physiological curves of the oral cavity, the 100° angled head enables easier access and high-torque cutting for efficient treatment in the oral cavity.Significantly expand the operational field of vision and reduce the fatigue of the wrist due to prolonged work.
Made of Stainless Steel(Head & Handle),Drop-resistant
Constructed with 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.
4-Point Precise Cooling Spray(Water-air separation system)
Independent water and air channels prevent water blockage caused by high air pressure. The 4-point spray creates a perfect mist for superior cooling and patient comfort.
4 points water spray system can help:
- Reduce overheating quickly
- Greatly improve patient’s comfort
- Improve cutting efficiency
- Extend cartridge lifespan
Premium dental turbines commonly highlight multi-spray cooling as a major performance feature.
Anti-Retraction Clean Head System
The anti-retraction structure helps reduce the risk of cross contamination by preventing contaminated fluids from flowing back into the turbine head and tubing system.
Integrated CNC Anti-leakage Head Design
Use an integrated head to avoid water leaking onto the head.Made of stainless steel,which has high hardness and is not easy to deform even when dropped on the ground. This significantly protects the cartridge inside the head.
Ceramic Bearing with Dustproof Structure
High-quality ceramic bearings provide:
- Lower noise
- Reduced vibration
- Longer service life
- Smoother operation
The dustproof design also helps reduce maintenance frequency during long-term use
Low Vibration,Low Noise
Low vibration is achieved through precision dynamic balancing of the rotor, high-tolerance silent bearings, a perfectly symmetrical impeller, strict coaxiality of the handpiece head, and an optimized air channel design that prevents turbulence and axial/radial shaking during high-speed rotation
