The core equipment and device of the air filter purification system is air filter.
Air filter refers to the air filter device, which is usually used in clean room, clean workshop, clean laboratory and purification room, or used in electronic and mechanical communication equipment. It is divided into primary efficiency air filter, medium efficiency air filter, HEPA filter . Different models have different standards and application. The main classification and characteristics of air filter and the application principles of high efficiency filter in junior middle school are emphatically described.We mainly introduce the classification and characteristics of air filers, what’s more, the application principles of air filters with primary efficiency, medium efficiency and high efficiency.
The use and replacement cycle of filter media is stipulated by its industry standard. It is also a commonly used industrial accessories and daily necessities. The filter screen resistance increases with the increase of filter screen dust, the resistance to air increases, the resistance to wind decreases, or the filter screen is partially penetrated, when the wind resistance pressure reaches a certain detection pressure value, the filter screen will be scrapped. Therefore, when using filters, we should grasp the appropriate cycle. When the filter screen is not punctured or damaged, its service life generally depends on resistance.
The classification and characteristics of various air filters.
Primary Efficiency Air Filter | Type | Panel filter, folded filter, bag filter. |
Outer Frame | Paper frame,aluminum alloy frame,stainless steel frame | |
Filter Material | Synthetic fiber,nylon mesh, activated carbon cotton, metal mesh | |
Characteristic | Can change the filtermedia, the paper frame is disposable | |
Application | Preliminary efficiency of air-conditioning system, mainly filter particles more than 5μm. | |
Medium Efficiency Air Filter | Type | Panel filter,bag filter |
Outer Frame | aluminum alloy frame,galvanized steel frame, stainless steel frame. | |
Filter Material | Non-woven fabric as main material, glass fiber paper | |
Characteristic | washable filter material, the service life is about 3-6 months. Higher filtering efficiency. | |
Application | Medium efficiency on ventilation system or air-conditioning system, mainly capture the particles more than 1μm. | |
HEPA Filter | Type | Panel filter,box filter |
Outer Frame | stainless steel frame, galvanized plate,aluminum alloy frame | |
Filter Material | glass fiber paper,A/B component glue, aluminum foil, offset paper | |
Characteristic | high filtering efficiency with large dust holding capacity, the service life is more than 1 year. | |
Application | Final filtration on air purification equipment,air ventilation system or air-conditioning system. High efficiency air supply outlet.Mainly capture the particles more than 0.3μm. |
