Configuration, performance and main features

• Control system: Computer-controlled operating system with a panel of preset function keys (reset, spittoon position, chair up/down, pitch, cold light, mouthwash, heated water, bowl flush and other function keys).
• Cabinet: Injection-molded 100% pure ASA material — airtight, dustproof and easy to clean.
• Frame: High-quality aluminum-alloy die-cast box frame; rust-resistant and dimensionally stable. Chair frame assembled by KUKA robot (accuracy ±0.08 mm).
• Instrument tray: Large injection-molded tray with 12-button operation panel and pressure gauge; instrument rack rotates 90°; integrated water, gas and electrical main switches.
• Assistant four-hand frame: Rotatable, with computerized mechanical buttons to control rinsing bowl, mouthwash and chair lift/tilt.
• Auto spittoon flush and cup filler: Solenoid valve control with adjustable water supply time; mouthwash has automatic constant-temperature heating.
• Saliva suction: Separate strong and weak suction system with external filter and cleaning/filter device for sediment removal.
• Oral lamp: 6-hole LED induction cold light with infrared induction switch; lamp beads configured as 4+2 LED white light; illumination memory; housing and handle disinfectable.
