Master Series High Speed Air Handpiece
The most powerful and amazingly quiet high-speed premium air handpieces designed.
The newest addition to KaVo’s high-speed collection, the GENTLEmini LUX 4500BR, is designed to complement KaVo’s best-selling handpiece, the GENTLEsilence LUX 6500BR, only with a smaller head. to further address the issues of patients who have difficulty opening their mouth wide for full oral access.
Our Master Series premium air handpieces operate at a very low frequency range; in fact, GENTLEsilence LUX 6500BR and GENTLEmini LUX 4500BR are two of the quietest high-speed air handpieces around. An extremely well-balanced turbine reduces acoustic pressure and high-frequency peaks to protect your hearing and helps create a relaxing environment for all. The unique ball-bearing technology guarantees quiet and virtually vibration-free operation.

There is now a market leading 2 1/2 year warranty now on all high-speed air handpieces to guarantee worry-free performance when maintained with a KaVo QUATTROcare. Standard warranty is two years.
KaVo high-speed premium air handpieces are unmatched in delivering everything on the list… and more. Our newly designed GENTLEsilence LUX 6500BR is the highest torque ever achieved by a high-speed air handpiece.
Sound reduction that sets a new standard

The 6500BR precision balanced turbine substantially reduces operating noise to only 57dB for a relaxed and safe working environment. (The human ear senses a reduction of 8-10 decibels as a 50% reduction in loudness). The 4500BR operates at a very quiet 59dB.
The 6500BR operates at a very low frequency range and the extremely well balanced turbine reduces acoustic pressure and high-frequency peaks to protect your hearing. (The human ear senses high frequencies at high decibel levels as unpleasant or painful).
With an optimized power output of 19 watts, the 6500BR provides the perfect balance of speed and torque for faster and more consistent preparations.
Best Access and Freedom of movement
- Unsurpassed motor region access with the shortest head of any high speed handpiece using a standard 19mm bur.
- Offers unprecedented visibility and accessibility unimpeded by the anterior teeth.
- Patented head and knee angle
- Smooth, compact handpiece design provides greater mobility and access for faster and easier preparations
- Exact preparations and gentler treatment
Slip free, comfortable control

Unique surface technology: The new 6500B features a unique Plasmatec surface that actually works with the innate gripping power of the glove for slip-free, comfortable control. And since there are no grooves or edges to harbor debris, the 6500B provides a durable grip.
Air Pressure Regulator
Unique integrated air pressure regulator extends handpiece life and assures optimized performance.
Multiple port spray cooling

Multiple spray ports are an important feature that:
- Provide faster cutting (SIEGEL, S., VON FRAUNHOFER, A.: The effect of handpiece spray patterns on cutting efficiency. JADA (Vol. 133, 02/02), p. 184f)
- Improves visibility
- Avoids overheating
- Extends bur life
- Provide better patient comfort
- Reduces risk of damage to the tooth structure
Outstanding visibility
KaVo cellular optics represent third-generation technology that is light years ahead of anything else. In fact, KaVo was the first to introduce glass rod technology in 1989. And since then, we've refined this technology to state-of-the-optical-art.
KaVo's 3rd generation cellular optic glass rods are 25% brighter than conventional optics, withstand sterilization with virtually no light degradation and are backed by a 5-year warranty on the glass rod.
Eliminates clogged water ports

A replaceable microfilter in spray-water channel guarantees efficient and reliable spray-cooling at all times
Anti return system

The new cartridge design incorporates an anti-suck-back system, which prevents contaminated particles from entering the turbine and head housing.
