Professional dental laboratory dustproof box designed for sandblasting and precision finishing tasks. Combines effective dust containment, strong suction, clear lighting, and an ergonomic interior to support longer, more accurate work sessions. Key features and benefits Dustproof filter box design: contains and minimizes the spread of dust during sandblasting to keep the work area cleaner and reduce dust accumulation on instruments and surfaces. Double suction system: powerful filtered electronic suction with dual inlets for improved dust collection and consistent airflow to protect nearby precision equipment from dust contamination. Shadowless 5500K LED light: integrated neutral white LED provides even, shadow illumination for clearer visual detail and reduced eye fatigue during detailed work. Ergonomic interior layout: tapered front and wider rear create a roomy workspace while allowing a natural 100degree hand spread to reduce arm strain and prevent fingers from hanging or pressing against the cabinet. Low noise and low vibration: engineered for quieter operation with minimal vibration to support concentration and stable handling. Easy maintenance: smooth interior surfaces and accessible filter components simplify cleaning and routine upkeep. Applications and use scenarios Sandblasting ceramic crowns and bridges where controlled dust containment and clear illumination improve finishing accuracy. Abrasive finishing and polishing of dentures, prosthetics, and small restorations to limit dust transfer to surrounding instruments. Trimming, cleaning, and preparing small dental components or models in a dedicated, dustmanaged workspace. Performance and compatibility Designed for dental laboratory environments and sandblasting workflows that require reliable dust extraction, consistent lighting, and an ergonomic working posture. Suitable for use alongside common dental lab equipment and precision instruments where dust control and clear vision are important. This dustproof box is intended to improve workspace cleanliness, visual comfort, and operator ergonomics during routine dental lab sandblasting and finishing tasks.
