• Ergonomic & Durable Construction: Built with a solid steel frame featuring anticorrosive treatment and coated in high-impact polystyrene for maximum security and longevity. The upholstery is made of high-resistance injected polyurethane, offering seamless, non-toxic, and anti-flame properties.
• Advanced Lifting System: Equipped with an electro-mechanical driven gearmotor for smooth, soft-start movements. This system eliminates the sensation of bumps, ensuring patient comfort and increasing engine life.
• Integrated Electronic System: Operates on a safe, low-voltage (24V) system that allows full interface with reflectors, equipment, and the Salvo electronic water unit. This ensures safety for both patient and professional while maximizing component durability.
• Precision Control: Features a joystick foot control with three work schedules, return-to-zero position, spit position, and chair movement locking. The PAD control panel allows easy management of chair positioning, reflector performance, and water flow.
• Hygiene & Maintenance: The Easy-Fix System allows for the practical removal of the backrest for quick cleaning and disinfection. The water unit includes a debris filter and a proximity sensor that automatically triggers water flow, enhancing hygiene and saving water.
• Complete Clinical Setup: Comes standard with a pneumatic lock arm, 1 triple syringe, 2 terminals for high rotation, 1 terminal for pneumatic micromotor, and 2 large instrument trays. The articulable arm offers freedom of movement with pneumatic locking.
• Optional Upgrades: Available with leather upholstery in 5 colors, water heating for the triple syringe, and advanced lighting options like the Sirius Sensor 3 LEDs or Sirius Sensor 3×2 LEDs (Yellow Light Technology) to inhibit early polymerization of composites.
