The handpiece includes universal tip no.1. Optional removable tip no.2 and no.3 expand its use. Body of handpiece is produced from stainless-steel to minimize the weight of this dental instrument. The hygiene of pneumatic scaler OZK93N is secured by sterilisation at 135°C. The scaler is connected to dental unit via special quick coupling Chirana 420N-4-ISO Midwest without light (quick-coupling 420N) Advantages: The advantage of pneumatic scaler OZK 93N is its reliability and wide range of possible applications, allowing usage for patients with cardiac pacemaker as well. For its full functionality doesn’t require an electrical source or any special module/control PCB. The advantage of the application of pneumatic scaler is especially in achieving of quality and efficiency of treatment. The ergonomic connection to pneumatic hose via quick coupling Chirana allows the connection of a quick-coupling turbine (range 637) together with Chirana pneumatic scaler OZK93N to the same instrument hose.
