1、 Filter leak detection
For the high-efficiency filter installed at the end of air supply and exhaust, the scanning method shall be used for filter installation frame and full section leakage detection. There are two scanning methods: leak detector method (photometer method) and particle counter method with a minimum sampling amount of 1l / min. For ultra-high efficiency filter, there are two scanning methods: condensation nodule counter method and laser particle counter method.

The air enters the clean room from the air-conditioning box through the air duct and the air filter (HEPA) in the clean room, and is returned by the partition wall panels or raised floors on both sides of the clean room. The airflow is in a state of irregular turbulence or eddy current due to non-linear motion. This type is suitable for clean room class 1,000-100,000.

The airflow in the clean room is an important factor affecting the performance of the clean room. Generally, the airflow speed of the clean room is between 0.25~0.5m/s. This airflow speed belongs to the breeze area and is easily disturbed by the actions of people and machines. . Although increasing the wind speed can suppress the influence of this disturbance and maintain cleanliness, the increase in wind speed will affect the increase in operating costs, so when the required cleanliness level i

Clean room refers to a well sealed space that controls air cleanliness, temperature, humidity, pressure, noise and other parameters as required
The development of clean room is closely related to modern industry and cutting-edge technology. Due to the environmental requirements of precision machinery industry (such as gyroscope and micro bearing processing) and semiconductor industry (such as large-scale integrated circuit production), the development of clean room technology is promoted
