空气过滤器的选择、布置和安装应符合以下要求：第一效果空气过滤器不得浸入油中；中效空气过滤器应设置在净化空调系统的正压段；高效空气过滤器或亚高效空气过滤器应设置在净化空调系统的末端，高效空气过滤器的安装方法应简单可靠、泄漏检测和更换；应根据额定风量选择中效、亚高效空气过滤器；在同一净化车间中设置具有相似阻力和效率的高效空气过滤器。
The selection, arrangement and installation of air filter shall be in accordance with the following requirements: the first effect air filter shall not be oil immersed; the medium effect air filter shall be set in the positive pressure section of purified
air conditioning system; the high efficiency air filter or sub high efficiency air filter shall be set at the end of purified air conditioning system, and the installation method of high efficiency air filter shall be simple and reliable, leakage
detection and Replacement; medium efficiency, sub high efficiency and high efficiency air filters should be selected according to the rated air volume; high efficiency air filters with similar resistance and efficiency should be set in the same purification
workshop.
在确定集中式或分散式净化空调系统时，应综合考虑生产过程的特点以及净化车间空气的洁净度、面积和位置等因素。生产过程连续、洁净室或净化车间面积较大的，对位置集中、噪声控制、振动控制要求严格的洁净室，应采用集中净化空调系统。
When determining the centralized or decentralized purified air conditioning system, the characteristics of the production process and factors such as the cleanliness level, area and location of the air in the purification workshop should be considered
comprehensively. Where the production process is continuous and the clean room or purification workshop has a large area, the centralized purified air conditioning system should be used for the clean room with centralized location, strict noise control
and vibration control requirements.
净化空气调节系统如需电加热时，应选用管状电加热器，位置应布置在空气过滤器的上风侧，并应有防火安全措施。
If the purified air conditioning system needs electric heating, the tubular electric heater shall be selected, which shall be arranged on the windward side of the high-efficiency air filter, and fire safety measures shall be taken.
送风机可按净化空气调节系统的总送风量和总阻力值进行选择，中效、空气过滤器的阻力宜按其初阻力的两倍计算。
The supply fan can be selected according to the total supply air volume and total resistance value of the purified air conditioning system, and the resistance of medium efficiency and high efficiency air filter should be calculated as twice of its initial
resistance.
净化工程中净化空气调节系统除直流式系统和设置值班风机的系统外，应采取防止室外污染空气通过新风口参入净化车间内的防灌倒措施。
In addition to the DC system and the system with duty fan, the anti pouring measures shall be taken to prevent the outdoor polluted air from entering the purification workshop through the new air inlet.
净化空气调节系统设计应合理利用回风，凡工艺过程产生大量有害物质且局部处理不能满足卫生要求，或对其他工序有危害时，则不应用回风。
The design of the purified air conditioning system shall make reasonable use of the return air. Where a large number of harmful substances are produced in the process and local treatment cannot meet the health requirements, or there is harm to other processes,
the return air shall not be used.
