The filter arrangement in class 100 clean operating room should meet the following requirements:
1. When parallel to the decorative layer or the equalizer layer is arranged on the air supply surface of the lower part of the static pressure box, the full coverage ratio of the filter shall not be less than 0.75.
Net cross section area of filter
Filling ratio of filters =-----------------------------------------------------------------------------------------------------------------------------------
Total area of filter section
2. When placed on the side of the hydrostatic chamber, it should be arranged unilaterally or contralaterally. The full coverage ratio of the filter on the side should not be less than 0.75. The air flow in the hydrostatic chamber should be fully mixed.
3. When the floor height is limited and indoor maintenance is not allowed, the air supply surface with leak-proof function can be used to arrange the filters outside the static pressure box, but the filters should be as close as possible to the static pressure box, the air flow in the static pressure box should be fully mixed, and the clean air flow rate should be less than 0.85.

4. In the clean area below level 100, when centralized air supply outlet is arranged, the final filter in the air supply outlet can be centralized or decentralized, but the equalizing layer must be set on the air supply surface.
5. All clean rooms in the clean operation department should adopt bilateral lower return air. When the distance between the two sides is not more than 3 m, one side of the lower return air can be used, but not the four corners or four sides return air should be used. Upper return air can be used in clean corridors and clean corridors.
6. The upper height of the lower return air outlet should not exceed 0.5m above the ground, and the lower side of the tunnel should not be less than 0.1M above the ground. The return air outlet of Class I clean operating room should be arranged continuously. The air velocity of indoor return air outlet should not be greater than 1.6 m/s, and that of corridor return air outlet should not be greater than 3 m/s.
7. Clean operating room should adopt indoor return air, no residual pressure valve to corridor return air.
8. Clean operating room must be equipped with upper air outlet, which should be located at the top of the patient's head. The blast speed of the exhaust outlet should be no more than 2m/s.
Air purification units should not be added to clean operating rooms of grade 9, I and II.
