The Venturi valve is a core airflow control device in HVAC and ventilation/purification systems, widely used in environments with stringent air quality requirements—such as hospital operating rooms, precision laboratories, pharmaceutical cleanrooms, and semiconductor manufacturing plants. Featuring excellent adaptive airflow regulation capabilities, it effectively addresses common industry challenges associated with traditional dampers, including poor adaptability to air pressure variations, low control precision, and airflow turbulence caused by system fluctuations; it serves as a specialized airflow control solution for high-end clean environments and precision ventilation systems.

Laboratory benches serve as core infrastructure for physicochemical laboratories and scientific research and testing institutions. Among the various types available, steel-wood and all-steel benches have become the mainstream choice due to their high adaptability, cost-effectiveness, and structural stability. The condition of components—such as work surfaces, cabinetry, steel frameworks, and hardware—directly impacts operational safety, data accuracy, and equipment longevity. Given the challenging laboratory environment—characterized by exposure to acidic and alkaline reagents, organic solvents, high-temperature equipment, and corrosive gases—these benches are prone to issues such as surface corrosion, paint peeling, cabinet deformation, hardware malfunctions, and the deterioration of piping. Standardizing equipment operation and maintenance is essential to delay aging, reduce failure rates, and ensure safe laboratory operations.
