4.7.4.5 High Efficiency Particulate Arrestance Filters (HEPA) 高效过滤器 High efficiency filters shall be of the absolute type or HEPA. They shall have a guaranteed minimum efficiency of 99.997% to the “HOT DOP” test method in accordance with BS 5750 Part One, (ISO 9001), (EUROVENT 4/5). The filters shall be an approved product by the Project Manager. Filters shall be constructed from class 700-pleated filter paper or fibre glass filters. The filter media shall be mounted in mild steel frames which shall be zinc and dichromate plated. Steel frames shall be

manufactured from material with a minimum thickness of 1.6 mm. The filter media shall be secured in the frames with corrugated aluminium separators and a sealant combination of closed cell polyurethane foam and a rubber based adhesive, or an approved equivalent material.

高效过滤器应是绝对高效过滤器或HEPA。根据BS5750第一部分、（ISO9001）、 (EUROVENT 4/5) 的要求，在“HOT DOP”实验下应保证99.997%的最低效率。过滤器应是经项目经理认可的类型。过滤器应使用700级褶皱的过滤器纸或玻璃纤维。过滤介质应固定在电镀珞的镀锌铁质框架上。该铁质框架的厚度不小于1.6毫米。过滤器介质应牢固装在框架内，并带有波纹曲面的铝制隔离器和由聚亚氨脂泡沫橡胶粘合剂组成的密封剂，或被认可的同等材料。

Supply, return or exhaust air HEPA filter elements shall be removable from within the clean room space. The filter elements shall be contained in an approved standard housing device. Provide 25.0 mm .diameter stainless steel tubes within the mounting frame to allow for the monitoring of the filter condition and to permit DOP testing. The tube shall be permanently fitted with a self-sealing quick release coupling. The installation shall be such as to ensure that there is no leakage past the filter during normal operation.

Ducts shall be provided with a 50-mm diameter port upstream of the HEPA filters to allow for the DOP injection. HEPA filters shall be accompanied by the appropriate test report stating the actual efficiency to the HOP DOP test. Filters shall also carry the BS 5750 Part One, (ISO 9001), (EUROVENT 4/5) compliance mark, or an approved equivalent mark of similar significance.

送风、回风和排风高效过滤器介质应可以从洁净室内拆卸下来。过滤器介质应固定在经认可的标准框架上。在框架上安装直径为25毫米的不锈钢管，以便用于监测过滤器的状态和进行DOP测试。该不锈钢管应为永久固定，带自动密封快速释放接头。安装应确保过滤器在正常运行时没有泄漏。风管应在高效过滤器的下风向处提供直径50毫米的端头，用于进行DOP测试时的注射。高效过滤器上应带有关于HOP DOP测试的实际效果的报告。过滤器也应遵守BS 5750第一部分，(ISO 9001), (EUROVENT 4/5)要求或类似标准。

Type种类 : HEPA/Absolute HEPA/绝对高效 Media介质 : Disposable 用后即可丢弃的

Duty效率 : 99.997% Arrestance to 0.3 micron 捕捉直径等于0.3微米微粒的

效率为99.997%

4.7.5 Filter Testing 过滤器测试

After completion of installation, all Type D and Type E filters shall be tested to confirm their filtration efficiency and integrity. Work shall be completed after all other commissioning and balancing, with all other pre-filters and equipment in place, and after approval to complete work has been granted by the Client.

在完成安装之后，所有种类D和种类E的过滤器应进行测试，以确认其过滤效率和完整性。该工作应在所有其他的试运行和调节完成后，并且所有其他的预过滤器和设备就位后进行，完成后应得到业主的认可。

A certified test report shall be completed and handed to the Client of completion of the testing.

在完成工作后，应完成和提交认证测试报告给业主。

Filters, which are tested and found to be unsatisfactory, shall be reported to the Client immediately. Damaged or leaking filter shall be replaced by the Contractor and retested at the Contractors expense until satisfactory results are achieved. Filters are not to be

repaired by application of silicone on site and will be rejected and replaced at the Contractor’s expense.

不满足测试标准的过滤器应立即向业主报告。损坏或泄漏的过滤器应由承包商进行更换和重新测试，直至达到满意的效果，并且由承包商承担所有费用。过滤器不可以在现场用硅胶修复，将被拒收和更换，由承包商承担所有费用。 4.7.6 Filter Installation 过滤器安装

Filters shall not be installed until the installation cleanliness has been approved by the Client in writing. All ductwork systems shall be thoroughly cleaned and all construction debris removed. The fans shall be operated for a period of not less than 8 hours with temporary dry media filters (Type A) over all return air and fresh air ductwork inlets to flush the system completely.

过滤器应在安装洁净度已经被书面标准认可之后方可安装。所有的风管系统应被完全清洁，同时所有的施工垃圾应被完全清除。在所有的回风口和新风进口都安装临时干介质过滤器（种类A）的情况下，风机应运行至少8个小时以彻底吹扫整个风管系统。

Each filter serial number and locations shall be recorded for future identification. Retain each filter certification sticker from the filter box and submit to the Client with the commissioning documentation.

每个过滤器的编号和位臵必须记录用于以后的识别。保留每个过滤器盒上的合格标签并遵循调试文件中的标准。

Dry media filters shall be delivered in individual plastic covers and kept covered up to the time of installation. Each filter shall be clearly identified with a model/media type. 干过滤介质的过滤器应运送至单独的塑料罩内封闭直至安装。每个过滤器应清楚表 …… 此处隐藏：5206字，全部文档内容请下载后查看。喜欢就下载吧 ……
