FEATURE:
1.Patented Anti-reaction design, protect hose and changer of dental units from pollutant.
2. Powerful Torque; Quiet Operation
3. Single-port spray with improved water atomization, better spray coverage.
4.Patented Anti-retraction device, saves disinfection costs.

DESCIPTION:
1.Back-flow Resistance Device, protects the hose and exchanger, of dental units, from back-flow pollutants,caused by negative pressure.
2.By designing and installing our original one-way in-line main back-flow resistance device.It not only achieves the anti-suction , but also protects the rear hose and the gas circuit exchanger from contamination. Really achieves the goal of effectively preventing back suction, thereby preventing cross infection.

ADVANTAGES:
Convenient for doctors
- Doctors no longer use regular handpiece, but use new handpiece every day.
-No longer use high temperature vacuum sterilization equipment, reduce cleaning, packaging, maintenance handpiece costs and labor input costs.
- Don't worry about sterilization and the infection caused by incomplete cleaning.
- Protect the dental treatment machine from contamination, and completely solve the problem of dental handpiece cross infection.
- Convenient for house visits and special use
