Clean Rooms Classification Of Air Filters
Clean Rooms Classification Of Air Filters There are many types of air filters for clean rooms. According to their structural forms, they are:
1. Flat filter
2. pleated filter
3.bag filter
4. Pleated filter with partitions
5. Pleated filter without partitions
Classification by filtration efficiency is the most common method; according to the national standards GB/T14295-93 "Air Filter" and GB13554-92 "High Efficiency Air Filter", under the rated air volume, there are:
2. Coarse filter
3.Medium efficiency filter
4. High efficiency filter
5. Sub-high efficiency filter
6. High efficiency filter filter h11

A filter that meets the h11 hepa filter specification has an efficiency of 99.998% for 0.1 microns and 0.3 microns. The characteristic of the HEPA network is that air can pass through, but fine particles cannot. Filter material: glass fiber filter material or polyester fiber (PP) filter material
It can remove more than 99.7% of particles with a diameter of 0.3 microns (1/200 of the diameter of a hair) and is the most effective filtering medium for pollutants such as smoke, dust, and bacteria. (The diameter of smoke particles produced by smoking is 0.5 microns)
Clean Rooms Classification Of Air Filters include: (acrylic), ordinary polyester fiber (PET) needle felt, high-strength polyester fiber (PET) needle felt, polyester fiber (PET) antistatic filter material (strip type), polyester fiber (PET) ) antistatic filter material (blended), polyester fiber (PET) needle felt-coated filter material, Meteflon medium-temperature filter material, polyphenylene sulfide (PPS) needle felt, PPS water-repellent and oil-proof filter material, aromatic Polyamide (METAMAX) needle felt, METAMAX coated filter material, METAMAX fiberglass composite filter material, polyimide (P84) needle felt, Metalon (PTFE) composite needle felt , Meters glass fiber composite filter material
