Looking for a more robust upgrade to our popular Prime 202 Dental Handpiece System? The Prime 221 introduces significant engineering improvements:
Higher Power & Torque: Upgraded from 100W / 4.8 N·cm to a stronger 120W output with 5.8 N·cm torque, preventing bit deceleration under sustained bench load.
Precise Digital RPM Display: Integrated front LED screen provides exact real-time speed monitoring, replacing guess-dial regulation.
Self-Diagnosis Error Feedback: Real-time diagnostic codes alert the operator to overload or thermal protection triggers before component damage occurs.
Ultra-Quiet Brushless Technology: Engineered with advanced electronic commutation to eliminate brush friction, delivering whisper-quiet operation and an extended operational lifespan during all-day bench shifts.
Ceramic Bearing Construction: Fitted with industrial-grade ceramic bearings that resist thermal expansion and wear, maintaining tight concentricity and virtually zero shaft runout up to 50,000 RPM.
Ergonomic Front Control Interface: Independent green rocker switches provide instant toggling between Hand/Foot pedal modes and Forward/Reverse rotation, paired with a tactile analog speed dial.
Slim Contoured Handpiece Grip: The Prime 221HP weighs only 201g and tapers down to 20mm at the front textured sleeve, ensuring steady, fatigue-free pen-grip control.
Industrial Rear Connections: Features a dedicated IEC power cord inlet, quick-release rear fuse holder, master power toggle, and a heavy-duty threaded foot pedal receptacle.
