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.




Our dust-free cleanroom series can be designed and built to suit clients who
require high-quality air filtration in the electronics, semiconductor, precision
fabrication, LCD manufacturing, optics, circuitry, and other related industries.
