HEPA is High Efficiency Particulate Air, so a HEPA filter is a High Efficiency Particulate Air Filter, also known as high-efficiency particulate absorbing filter and high-efficiency particulate arrestance filter,is an efficiency standard of air filter.
Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards require that a HEPA air filter must remove-from the air that passes through-at least 99.95% (ISO, European Standard) or 99.97% (ASME, U.S. DOE) of particles whose diameter is equal to 0.3 μm, with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm.[8] HEPA filters capture pollen, dirt, dust, moisture, bacteria (0.2-2.0 μm), virus (0.02-0.3 μm), and submicron liquid aerosol (0.02-0.5 μm).[11] Some microorganisms, for example, Aspergillus niger, Penicillium citrinum, Staphylococcus epidermidis, and Bacillus subtilis are captured by HEPA filters with photocatalytic oxidation (PCO). HEPA is also able to capture some viruses and bacteria which are ≤0.3 μm. HEPA is also able to capture floor dust which contains Bacteroidia, Clostridia, and Bacilli. HEPA was commercialized in the 1950s, and the original term became a registered trademark and later a generic trademark for highly efficient filters. HEPA filters are used in applications that require contamination control, such as the manufacturing of hard disk drives, medical devices, semiconductors, nuclear, food and pharmaceutical products, as well as in hospitals, homes, and vehicles.
HEPA Filter is divided intoDeep-pleated HEPA filter and Mini-pleated HEPA filter.
Deep-pleated HEPA filter
Specialty:
* Collecting 0.3 Micron or below particles and used as the terminal filtration.
* Deep-Pleated HEPA filter is processed by super fine fiberglass media or PP media separated by sized paper or aluminum foil with new polyurethane gasket, there is MDF, galvanized steel, stainless steel, aluminum frame available.
* Each HEPA Filter is individually tested via PSL particle, Using MPPS (DOP Test) laser particle counting device to measure overall efficiency of the filter.
* It is featured with high efficiency, low resistance, high dust holding, long working life, easy installation.
* Temperature resistance: 80℃, relative humidity is 80%.
Application:
It is widely used as terminal filter in top grade purifying equipments of Electronics Factory, semiconductor, precision, mechanism, pharmaceutical factory, hospital, food sanitation etc.
Mini-pleated HEPA filter
Specialty:
* Mini-pleated HEPA filter can collect 0.3 Micron or below particles and used as the terminal filtration.
* It is processed by super fine fiberglass media separated by hot-melt adhesive with double polyurethane gasket. Inside sponge can avoid any leakage. Injection molding mesh can protect the inside media very good.
* The pleated type can form a ventilation channel, increase filtration area and airflow, decrease the resistance.
* It is featured with high efficiency and dust holding, low resistance, uniform airflow, easy installation.
* It is individually tested via PSL particle, Using MPPS (DOP Test) laser particle counting device to measure overall efficiency of the filter.
* Temperature resistance: 80℃, relative humidity is 80%.
Application:
Mini-pleated HEPA filter is widely used as terminal filter in top grade purifying equipments of Electronics Factory, semiconductor, precision mechanism, pharmaceutical factory, hospital, food sanitation etc.
