NSK Ti-Max Z890 Mini Head LED Airotors (Z890L / Z890KL)

• Titanium body with DURAGRIP coating provides lightweight strength, secure grip, and reduced hand fatigue during extended procedures.

• DYNAMIC POWER SYSTEM optimizes air-to-power conversion to deliver stronger cutting efficiency with a high torque feel.

• Integrated Cellular Glass Optics ensure clear, consistent illumination for enhanced intraoral visibility.

• High-precision ceramic bearings support smooth high-speed rotation and long-term durability.

• Advanced Clean Head System reduces suck-back and prevents contaminants from entering the head for improved hygiene and extended bearing life.

• Simple cartridge change system allows quick and convenient replacement, minimizing clinical downtime.

• Ergonomic push button chuck enables fast and easy bur insertion and removal.

• Quattro Spray cooling system effectively surrounds the bur to reduce heat generation during cutting.

• Built-in microfilter prevents debris from blocking the spray system, ensuring consistent water flow.

• Quick Stop function halts rotation in approximately 1 second, reducing inertial spin and enhancing procedural safety.

• Reinforced DURAPOWER CHUCK maintains strong bur retention for stable cutting and minimized slippage risk.

• Fully sterilizable up to 135°C, ensuring compliance with infection control protocols.

1) What is the practical benefit of the 100° angled head in the Ti-Max Z890 series?

The 100° angled head improves access and visibility in the oral cavity, especially in posterior regions, while supporting efficient high-torque cutting.

2) What is the difference between Z890L and Z890KL?

Z890L connects to NSK coupling while Z890KL connects with Kavo coupling.

3) How fast does the Quick Stop function work and why is it important?

Quick Stop halts high-speed rotation in around 1 second, reducing inertial rotation and lowering the risk of intraoral entrapment and suck-back.

4) What infection-control features are included?

Both variants include the Clean Head System and Quick Stop, which help reduce suck-back and improve hygiene and patient safety.

5) Can these turbines be sterilised and thermodisinfector cleaned?

Yes. Both Z890L and Z890KL are sterilizable up to 135°C and washable in the thermodisinfector.
