技术特点
Technical characteristics
( 1 )进入室内的层流空气已经过高效过滤器滤过，达到无菌要求;
(1) the laminar air entering the room has been filtered through the efficient filter to meet the aseptic requirements.
( 2 )空气呈层流形式运动，使得室内所有悬浮粒子均在层流层中运动，则可避免悬浮粒子聚结成大粒子;
(2) the air is laminar movement, which makes all the suspended particles moving in the laminar layer, so that the suspended particles can be avoided into large particles.
( 3 )室内新产生的污染物能很快被层流空气带走，排到室外;
(3) the indoor new pollutants can be quickly taken away by laminar air and discharged to the outdoor.
( 4 )空气流速相对提高，使粒子在空气中浮动，而不会积聚沉降下来，同时室内空气也不会出现停滞状态，可避免药物粉末交叉污染;
(4) the relative velocity of air increases, which makes particles floating in the air without accumulating and settling. At the same time, indoor air will not stagnate, so that the cross contamination of powder can be avoided.
( 5 )洁净空气没有涡流，灰尘或附着在灰尘上的细菌都不易向别处扩散转移，而只能就地被排除掉。层流可达到 1 万级，甚至 100 级。
(5) clean air has no swirl, dust or bacteria attached to the dust are not easy to spread elsewhere, but can only be removed to the ground. The laminar flow can reach level 10 thousand or even 100.
