The four major technical elements of a clean room are: coarse, medium and high-efficiency three-stage filtration, sufficient purification air supply volume, the establishment and maintenance of indoor positive pressure, and the setting of terminal high-efficiency or ultra-high-efficiency filters. The clean room high-efficiency filtration membrane material is used here.
High-EfficiencyParticulateAir, a high-efficiency air particle filter, or HEPA for short.
HEPA-compliant filters are used in a wide range of applications, from medical equipment to automobiles, aircraft and homes.
The filter standard is set by the U.S. Department of Energy. For particles with a particle size of 0.3μm, the filtration effect is approximately DOP99.97% or above.
The commonly used high-efficiency filter can achieve an interception efficiency of 99.99%.
HEPA filters have complete classification, retaining coarse-efficiency filters, medium-efficiency filters, sub-efficiency filters and ultra-efficiency filters.
According to the different scope of use, it can also be divided into medical and other related classifications.
In terms of manufacturing materials, HEPA manufacturing also includes glass (830, -3.00, -0.36%) fiber and plastic (8000, 195.00, 2.50%) fiber and other materials.
Clean room high-efficiency filtration membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can be up to 50%-80%. It is suitable for various clean rooms from level 1 to level 100000.
It is a clean room high-efficiency filtration membrane manufacturer specializing in R&D, production and sales.
It is also a provider specializing in technology development, transfer, consulting, and services in the field of new materials; R&D, production, sales, and customization; and high-efficiency separation and filtration material design solutions.
