Class 10,000 (Partial Class 100) Clean Laboratory

QQ截图20211105160436

The clean room differs in airflow design according to different grades. Generally, it can be divided into vertical laminar flow (Class1-100), horizontal laminar flow (Class1-1,000), and turbulent flow (Class1,000-100,000). The detailed distinction is as follows:

Airflow method Cleanliness Wind velocity
(/s)
Air change rate (/h) Air inlet Advantage Disadvantage
Vertical laminar flow Class1-  Class100 0.25- 0.40 200- 60 Blow out: more than 80% of the ceiling. Inhalation: more than 40% of the wall panel, also from the side panel. The effect is complete,Not easily affected by operators and operating status,It becomes stable immediately after starting operation,There is very little dust accumulation and re-floating,Easy to manage.  Pay attention to the void space in the ceiling (lighting, etc.)It is troublesome to change the filter,The equipment cost is very high,The expansion of the house is more difficult.
Horizontal laminar flow Class1- Class1,000 0.45- 0.50 200-600
100-200
Blow out: more than 80% of the siding. Inhalation: more than 40% of the siding, also from the ceiling. It becomes stable immediately after the operation starts, and the structure is simple. The upstream influence will appear downstream,Attention must be paid to the configuration and management of personnel and machines,The equipment cost is very high,The expansion of the house is more difficult.
Turbulent flow (traditional) Class1,000-
Class100,000
  30-60 Blow out: the filter has a better outlet. Inhalation: from near the floor. Simple structure,Low equipment cost,The expansion of the house is easier,If you add a dust-free table, you can ensure high cleanliness. Pollution particles may circulate indoors due to the turbulence of the airflowIt takes a while to reach a stable state,Attention must be paid to the configuration and management of personnel and machines.
