1. 气流模式:30%外排，70%循环。
2. 内部尺寸(W×D×H): 1200×630×780 mm或大小相当尺寸
3. 外部尺寸(W×D×H): 1300×802×1520 mm或大小相当尺寸
4. 前窗工作开口高度≥250mm; 前窗最大开口高度≥500mm。
5. 过滤效率:最易穿透颗粒（MPPS）过滤效率高于 99.995%; 对0.3微米颗粒过滤效率高于99.999%。
6. 工作台面材料: 防眩目涂层分体式内壁。
7. 噪音:≤70dB。
8. 照度：≥1200lux。
9. 独立双风机系统
10. 具有风速测定及风速变化量≥20%时报警系统。
11. 具有低速节能模式：前窗完全关闭后，风机可继续工作，并自动降低下降风速至少30%。
12. UV灯管可定时操作（0-24小时定时控制）。
13. 前窗玻璃具为防紫外线防爆玻璃，即使发生破裂，玻璃碎片将吸附在贴膜上不会发生飞溅，防止人身伤害。
14. 前窗玻璃可下滑到人手臂位置上，操作者可站在安全柜外的无污染区，无需将头探入安全柜就能彻底清洗安全柜。
15. 前窗具有倾角斜面，防止眩光产生，影响操作。
16. 控制面板有时间显示，风速显示(下降风速,进风风速)，总工作时间显示，定时器，UV灯工作时间，实时显示整个柜体的状态（包括运行是否安全，是否需要检修）。可直观显示安全柜总体运行状态：如绿灯正常使用，黄灯需要注意，红灯需要等待，长时间红灯需要维护。 1. Air flow mode: 30% external exhaust, 70% circulation.
2. Internal dimensions (W×D×H): 1200×630×780 mm or equivalent
3. External dimensions (W×D×H): 1300×802×1520 mm or equivalent size
4. The working opening height of the front window is ≥250mm; the maximum opening height of the front window is ≥500mm.
5. Filtration efficiency: The filtration efficiency of the most penetrating particles (MPPS) is higher than 99.995%; the filtration efficiency of 0.3 micron particles is higher than 99.999%.
6. Work surface material: anti-glare coating split inner wall.
7. Noise: ≤70dB.
8. Illumination: ≥1200lux.
9. Independent double fan system
10. Equipped with wind speed measurement and alarm system when the wind speed change is ≥20%.
11. With low-speed energy-saving mode: after the front window is completely closed, the fan can continue to work and automatically reduce the downward wind speed by at least 30%.
12. The UV lamp can be operated regularly (0-24 hours timing control).
13. The front window glass is UV-proof and explosion-proof glass. Even if it breaks, the glass fragments will be adsorbed on the film and will not splash, preventing personal injury.
14. The front window glass can slide down to the position of the human arm, and the operator can stand in the pollution-free area outside the safety cabinet, and can thoroughly clean the safety cabinet without poking his head into the safety cabinet.
15. The front window has an inclined surface to prevent glare and affect operation.
16. The control panel has time display, wind speed display (downwind speed, inlet wind speed), total working time display, timer, UV lamp working time, and real-time display of the status of the entire cabinet (including whether the operation is safe and whether maintenance is required). It can visually display the overall operating status of the safety cabinet: if the green light is in normal use, the yellow light needs attention, the red light needs to wait, and the red light needs maintenance for a long time.
