Selection, layout and installation of air filters in dust-free workshops
The air purification treatment system in the decoration of all levels of dust-free workshops should generally use three stages of primary, intermediate and high efficiency air filters. The outdoor fresh air must pass through the above three-stage filtering, and the indoor return air can only pass through the medium-efficiency and high-efficiency two-stage filtering. 级乱流无尘车间，经计算能满足洁净度要求的情况下，末级空气过滤器可以采用亚高效过滤器，但应 For a 100,000 -level turbulent dust-free workshop with a well-sealed room and a reasonable layout , it can be calculated that the cleanliness requirements can be met.
～ 20% 。 According to factors such as the concentration of outdoor dust, the number of air changes is increased by 10% to 20% compared to high-efficiency air purification systems . 100000 级的一般洁净房间，末级过滤器可采用亚高效过滤器或高中效过滤器。 For general clean rooms with a cleanliness level below 100,000 , the final filter can be a sub-high efficiency filter or a high-medium efficiency filter.
1 . The primary effect air filter should be a non-woven primary effect filter, or a coarse-cell foam plastic filter. An oil-immersed filter should not be used. The filter can be combined in the air conditioner or installed separately on the fresh air pipe.
2 . Medium-efficiency air filters generally use non-woven fabric medium-efficiency filters and glass fiber medium-efficiency filters, and high-tech or electrostatic filters with synthetic fibers as filter materials can also be used. Medium-efficiency filters are generally installed centrally, taking into account the convenience of maintenance. A gasket is required at the connection between the filter and the frame.
3 ． Most high-efficiency air filters use glass fiber filter paper as the filter material. Should be set at the end of the air supply system of purification air conditioning. The installation of high-efficiency filters requires reliable sealing measures and is easy to detect and replace. When higher education filters are installed on the side (such as side delivery, horizontal laminar flow clean room air supply wall, etc.), the corrugated board should be perpendicular to the ground.
4 . Purification air-conditioning systems using diffuser air supply, high-efficiency filters should be installed centrally, but must be in the positive pressure section of the system.
5 . The design air volume of the primary and intermediate air filters should be selected according to the rated air volume. The design air volume of the sub-efficient, higher education air filter of the turbulent dust-free workshop should be selected according to the value slightly less than the rated air volume. The design air volume of the laminar flow clean room high efficiency filter should be determined according to the requirements of the layout
