What are the performance characteristics of the filters used in cleanrooms?

I. Structure of the design

To ensure that the airflow in the room is not disturbed, the structure must be rigorously designed to prevent the accumulation of dust anywhere in the room.

II. Cleanliness and number of air changes

The cleanliness of the room depends on the number of air changes of the equipment, so the nature of the indoor work, production processes, etc. must be carefully considered before deciding on the technical parameters used in the purification system.

III. Choice of materials

The materials used for the roof, walls, and floor of the clean room must also be chosen so that they do not break easily and stain the dust.

IV. The design of the scheme

Before determining the design scheme must take into account the nature of the work of the clean room and the airflow conditions, etc., in these aspects of comprehensive consideration after making a decision, for example, the amount of dust is not suitable for the workshop using the form of ground air supply; cleanliness requirements are relatively high workshop should be as far away from other workshops, etc.

V. System design

Clean room air purification system can be generally divided into horizontal laminar flow, vertical laminar flow, and chaotic flow of these three, the choice is made concerning the practice, or depending on the various parameters of the room.

VI. People and objects

The people and objects entering and leaving the clean room are the dominant ones and the main source of pollution, so strict control must be carried out, for example, by stipulating that all people must be blown through the air shower room before entering the clean room and changing special work clothes, etc.

VII. Drainage system

According to the different work requirements of the clean room need to provide the necessary water supply and drainage devices, air supply devices, and power supply, these devices and equipment must be easy to use, while not interfering with the operation of the air purification system.

VIII. Auxiliary facilities

In the design of the clean room, some auxiliary equipment can be installed when necessary, such as air indicators for the new air outlet, transfer windows on partitions, etc. The choice of these devices must also be in line with the clean requirements of the room.
