Key Benefits: Precision, Efficiency, and Safety for Your Lab

Our Class II Type A2 Biological Safety Cabinet is more than just a piece of equipment; it is a solution designed to address the real-world challenges you face daily. We have focused on core features that deliver tangible benefits, enhancing your lab's safety and the reliability of your sensitive work.

• Triple Protection: The 70% recirculation and 30% exhaust airflow ratio, combined with HEPA H14 filtration, provides uncompromising protection for the operator, product, and environment. This directly solves the common pain point of exposure risks and cross-contamination when handling hazardous biological materials.

• Smart DC ECM Motor with Constant Air Volume: The DC ECM motor saves 60% energy and features an intelligent constant air volume compensation system. Even when HEPA filter resistance increases by 50%, the inflow air volume change remains less than 10%, ensuring safe operation throughout the entire life span of the filter.

• Accurate Control and Display: The full-color LCD screen displays downflow and inflow air velocities with extreme precision (0.001 m/s accuracy) using an imported Japan velocity sensor. Filter service life and blower operation status are clearly visible, with built-in alarms for safety.

• Humanized and Ergonomic Design: The compact tabletop design fits into limited spaces. The 10° sloped front, demountable circular-arc armrest, and optimized sliding window lifting system ensure comfortable operation under severe conditions.

• Safe and Reliable Construction: The negative pressure surrounding the double-layer cabinet uses "leakage resistance" and "unobstructed return air" technology. The sliding window is interlocked with the LED light and UV lamp to prevent accidental UV exposure.

• High-Quality Filter Material: Made with imported filter material, the high-efficiency filter achieves a large dust holding capacity and high uniformity. Strict cabinet leak prevention and filter integrity testing guarantee reliable performance.
