Bien Air EVO.15 CLASSIC E-Type CA 1:5L Highspeed Optic Electric System Attachment


ACCURATE: High efficiency and cutting-edge technology come together on the Contra Angle EVO.15. The new Accu-Chuck PreciPlus™ bur-retention and rotation drive mechanism* is a perfect example of that – its vibration-canceling properties not only reduce noise interference, they also authorize perfect stability and accuracy no matter the speed and torque. Due to durability being a key contributor to performance, the Contra-Angle EVO.15 is fitted with a specially-designed rotor’s head that demonstrates significantly longer service life than conventional models.

The most advanced engineering techniques, skilled company know-how, and up to 3 years of warranty put in your hands the quality and reliability our competitors have been trying to match for over 50 years.

PRACTICAL: The size of the Contra-Angle EVO.15 makes you forget that you are handling such a high-performance instrument. Its small, shockproof stainless steel head provides remarkable maneuverability and accessibility to third molars. As part of Bien-Air’s Micro-Series line, the handpiece’s comparatively lighter weight pushes the limits of comfort even further with more balanced manipulation and reduced hand and wrist fatigue.

To maximize user experience, every aspect of the Contra-Angle EVO.15 has been carefully thought-out. The improved Accu-Spray Quattro Mix™ and its dualook™ non-dazzling multi-strand optical glass system support this statement and need to be credited for competent operative field cooling and reliable intraoral visibility.

SAFE: The Contra-Angle EVO.15 expresses itself in multiple ways, and patient safety is unmistakably at the forefront. Bien-Air’s patented* CoolTouch+™ heat-arresting technology brings the handpiece closer to zero risk when it comes to patient burn injuries. Similarly, adverse events linked to bur slippage are prevented, thanks to an extremely efficient fastening system.

When brought together, these combined safety features make the Contra-Angle EVO.15 the safest electric handpiece ever designed.
