    • A clean room is supplied with air at a controllable velocity from a blower with a variable damper mechanism. The ceiling of the clean room is comprised of a plurality of panels of particulate filter material. Associated with at least some of said panels are air dampers comprised of first and second adjacent perforated plates. The first plate is fixed and the second plate is mounted for translational movement relative to the first. By moving the second plate relative to the first, the perforations therein are selectably opened or occluded, permitting the air passing through each panel to be regulated. Air flow through the room as a whole is controlled by the variable air flow feature of the blower.
    • 洁净室以可变阻尼机构从鼓风机以可控的速度供应空气。 洁净室的天花板由多个微粒过滤材料板组成。 与至少一些所述面板相关联的是由第一和第二相邻多孔板构成的空气阻尼器。 第一板固定,第二板安装成相对于第一板平移运动。 通过相对于第一板移动第二板,其中的穿孔可选地打开或闭塞,允许通过每个板的空气被调节。 整个房间的气流通过鼓风机的可变气流特征来控制。
