Choose appropriate air pressure
If air pressure exceeds the rated value, the speed of the drill will be so fast that the bearing and bearing cage can become prematurely worn and their service lives can be shortened. If the air pressure is too low, the speed can be too slow to properly perform the intended function of the dental equipment.
|Handpiece's type||Appropriate air pressure(Mpa)|
|High speed handpiece with mini head||0.20-0.22|
|High speed handpiece with standard head||0.22-0.25|
|High speed handpiece with big head||0.25-0.30|
|Low speed handpiece||0.30-0.35|
How to guarantee the appropriate air pressure during actual use?
As shown in the figure: When installing the dental chair, the installer will adjust the pressure value to match the high or low speed handpiece. However, the air pressure will fluctuate after changing the handpiece because there are design differences among different brands. Therefore, the users should step on the pedal switch to check the working pressure and adjust air pressure according to the type of handpiece.
Clinic dental chairs are usually in a series, so there may be a situation where air pressure is not enough when multiple devices are working at the same time (even if the user adjusts the pressure valve). In this situation, please wait for a few minutes until the air reservoir's pressure rises.
The air compressor extracts air and compresses it to supply to the dental equipment. Water and other impurities in the air reservoir can cause corrosion, accelerate the aging of the dental chair pipeline as well as shorten the service life of handpiece and other devices. It can even lead to infection if not cleaned properly. Therefore, the users should keep the air pump dry and change the filter regularly.
Most clinics in China use tap water directly while clinics in European and American countries often use filtered/distilled water.
Water quality varies from region to region, and the impurity of water affects the service life of equipment. We advise the users to add filters and use distilled water if the conditions permit. With tap water, it is not recommended to be equipped with a three-hole/multi-hole handpiece.
To ensure the air and water supply is clean, please check air pump and filter before using.
Chose the appropriate bur
The bur is a wearable part, if you need change the bur, please choose the bur which meets ISO international standards.
High speed handpiece's bur diameter: Φ1.59mm- Φ1.60mm
Low speed handpiece's bur diameter: Φ2.350mm
