摘要： A pre-assembled, self-contained clean room module having everything necessary for maintaining the cleanliness, temperature, humidity and pressurization required for the work space within the room. Because the module is factory built rather than built on site, precise quality control can be achieved and each module can be thoroughly tested before shipment. The module is provided with its own sealed base unit which permits it to be moved or relocated without having to be disassembled, and also insures that the module will have a completely sealed sump area beneath its floor. The module is also provided with its own self-contained air conditioning unit which has two independent air systems or paths whereby only a portion of the recirculating air need be conditioned.
摘要翻译：一个预组装的，独立的洁净室模块，具有维护室内工作空间所需的清洁度，温度，湿度和加压所需的一切。由于该模块是工厂内置而不是现场构建，因此可以实现精确的质量控制，并在出货前对每个模块进行彻底测试。该模块设置有自己的密封基座单元，允许其移动或重新定位而不必拆卸，并且还确保模块将在其底部下方具有完全密封的储槽区域。该模块还设有自己独立的空调单元，该单元具有两个独立的空气系统或路径，由此只有一部分循环空气需要调节。

摘要： This device is for balancing air flow and the dispersion of air around duct throats, and is particularly adapted for already manufactured filter modules and ceiling air conditioning diffusers, where concern for spreading fire through the openings is involved. Primarily, it consists of a core assembly for the filter module hood. The assembly includes a mounted bolt and a pair of perforate discs, which will serve as a flame barrier automatically, when fire is present, and the assembly further includes a low melting point solder for its automatic operation.
摘要翻译：该装置用于平衡气流和管道喉管周围空气的分散，并且特别适用于已经制造的过滤器模块和天花板空调扩散器，其中涉及通过开口扩散火焰。主要由滤芯组件罩组成。组件包括安装的螺栓和一对穿孔盘，当存在火灾时，其将自动地用作阻火挡板，并且组件还包括用于其自动操作的低熔点焊料。
