Air Class Requirements for Class 100,000 Cleanrooms


The 100,000-level dust-free workshop indicates that the number of dust particles with a diameter of 0.5um or more per cubic meter of air is less than 100,000. The so-called 100,000 level means that the number of 0.5 micron dust particles allowed in one foot of space is within 100,000.
In order to ensure the air purification cleanliness required by the 100,000-level dust-free workshop of the product production environment or other uses, a variety of comprehensive technical measures can be taken to meet the requirements.
These comprehensive technical measures include adopting production processes and equipment that generate less pollutants, or adopting necessary isolation and negative pressure measures to prevent the pollutants produced by the production process from spreading to the surroundings, and using interior decoration materials that generate less dust and are not prone to breeding microorganisms And tools to reduce the amount of pollutants brought into the room by personnel and materials, and maintain a positive pressure in the production environment relative to outdoor or adjacent rooms with low air cleanliness requirements, preventing air in the outdoor or adjacent rooms from carrying pollutants through doors and windows Intrusion of other gaps and holes, strengthening the management of the clean room, cleaning and sterilization according to regulations.
In addition to the above-mentioned technical measures, in order to control the indoor environment of a 100,000-level dust-free workshop in the production environment or other uses to the required level of air cleanliness, an important technical measure is to send a sufficient amount of processed cleaning The air is used to replace or dilute the air contaminated by pollutants generated during normal work in the room. The air purification treatment in the clean room is sent to the treated volume in different ways according to the different cleanliness requirements of the room. Clean the air, and at the same time remove the corresponding amount of dirty air that is polluted with pollutants generated indoors. By this dynamic balance, the indoor environment is maintained at the required level of air cleanliness.
