Briefly describe the static pressure difference that the clean workshop needs to have

Maintaining the corresponding positive pressure in the clean workshop is one of the important conditions to ensure that it is not polluted or less polluted, so as to maintain the design cleanliness level. Even if it is a negative pressure clean room modular, it must have an adjacent clean room modular or suite that is not lower than its cleanliness level to maintain a corresponding positive pressure, so that the cleanliness of the negative pressure room can be maintained.

Positive pressure value refers to the value that the indoor static pressure is greater than the outdoor static pressure when the doors and windows are closed. It is achieved by the method that the air supply volume of the purification system is greater than the return air volume and the exhaust air volume. In order to ensure the positive pressure value of the clean workshop, it is recommended to interlock the supply air, return air and exhaust fan. When the system is turned on, start the supply fan first, and then start the return fan and exhaust fan; To avoid contamination when the system is turned on and off.

The air volume required to maintain the positive pressure of the clean workshop is mainly determined according to the airtightness of the maintenance structure.

At the same time, as the recent research of PHARMA shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
