Description
The J2-SU high speed dental handpiece makes less noise when working, thus providing a comfortable treatment environment for both the dentist and patient. It features a hygienic head inside, and utilizes push button burr changing and single point water spraying. Users can choose between two hole or four hole types, and a dental cartridge that is compatible with NSK PANA MAX2 handpieces is used.

• A hygienic head system is installed inside the turbine handpiece in order to prevent the suction of blood, viruses, and skin particles caused by a negative pressure produced when the handpiece operation stops, thus, preventing cross infection. This also protects the dental drill cartridge to avoid damaging the bearing with foreign matter, significantly improving the service life of the hand piece.

• The top of cartridge features a movable structure to improve the balance of upper and lower bearings, thus avoiding friction on the back cover while the movement shell is rotating at a high speed. This decreases noise and vibration levels of the handpiece, extending its service life.

• It is designed with special structure that features 4 grooves for added movement. This allows for excess gas inside to flow out smoothly, contributing to a lower noise and lower vibration efficiency, while also ensuring the revolutions needed for normal cutting.
