ISO 14644 Dust Free Clean Room HEPA ACR Electronic Clean Room

Yijing Dust-Free Cleanrooms

E-Clean builds and designs dust-free cleanrooms ranging from FS209E levels 100
to 100,000, which equate to ISO 14644 levels 5 to 8. For 300,000-level
cleanrooms, a sub HEPA filter may be used. For levels 100-100,000, we recommend
installation of a system of primary, secondary, and high-efficiency HEPA
filters. The airflow rates of the secondary and high-efficiency filters should
be less than or equal to the specified airflow rate of the cleanroom. Secondary
filters should be concentrated around the barotropic section of the air
handling system, while the high-efficiency filters should be concentrated
around the end of the air handling system





Additional Considerations for Dust-Free Cleanrooms

Dust-free cleanrooms maintain a positive pressure environment and control the
number of dust particles in the air via an advanced filtration system. In
addition to the filtration system, the level of cleanliness in a cleanroom is
determined by internal and external environmental factors, such as the amount
of people and equipment contained within the cleanroom and the amount of
traffic passing through the room. The amount of air changes per hour (air
change rate or ACR), air velocity, method of airflow, fan size and fan speed
are just some of the variables that we consider when designing a world-class
cleanroom solution for your enterprise.
