Mini Polisher is a kind of dental scaling equipment which is used synthetically with complex treatment method in dental surgery. It is connected to the joint of high speed manual machine of complex treatment unit, the air souse (0.3Mpa-0.4MPa) and water source (0.2MPa-0.4MPa)on complex treatment unit will control air pressure and water pressure of Mini polisher. 
The operating principle of Mini polisher is as follows: The sand blasting powder in case would spurt out from nozzle via pipeline by compressing the air into case at the time of powder spurting out, it mixes with water spurting out from mouth of Mini polisher to form into a foggy mixture. And this mixture would spray on the surface of teeth. 

Design features: 
1. The appearance is handsome and dexterous and the structure is indiscrete. 
2. Directly connecting to complex treatment unit, so it is very handy. 
3. It is easy to replace the working head of Mini Polisher. And it can be sterilized in condition of vacuum with temperature of 135. 
4. Anti-resorption facility in san blasting gun can prevent sand blasting powder to be back-adsorbed into complex treatment unit. 
Technical parameters: 
1. Mini polisher can be divided into two types according to connection mode: Fast connections (NSK) and 4 ways connector . 
2. Water pressure: 0.2Mpa-0.44MPa 
3. Air pressure: 0.3Mpa-0.4MPa 
4. Water spraying amount of working head: 30ml/min 
5. Sand blasting amount of working head 2.4g-3.2g/min
