The life of HEPA filter
Synonymous with so-called HEPA filter is efficient filtration equipment, especially the HEPA filter which is subject to the warm welcome everyone, especially in various industries, it is not the lack of!
As everyone knows, with the rapid development of modern industry, the application of various filtration equipment is very wide, accompanied by serious environmental pollution, our environmental awareness has been continuously strengthened, air quality has become a focus of attention around the world, from which we can see, the widely used HEPA filter equipment is also not without reason the!
The HEPA filter is mainly composed of superfine polypropylene (PP) fiber or glass fiber filter (HEPA), non-woven (coarse filter), a hot melt adhesive, sealant, frame materials such as paper shell edge and other materials. Glass fiber filter paper which is composed of various thickness, length of glass fiber through special process produced, which is characterized by high temperature resistance, high efficiency, large dust holding capacity, good stability, long service life etc..
Many people may not know, efficient filter our early use of mostly is made by glass fiber filter paper, but with the development of science and technology, new chemical materials, these materials will gradually be replaced chemical fiber filter. However, in the high efficiency filter, especially for the cleanliness of the more stringent requirements of the occasion, the use of glass fiber filter or more, while the HEPA high efficiency filter we is one of a kind.
These devices use a filter to show the effect of three-dimensional, filament diameter is 2-18 μ m, reticular structure special reduces the filtration resistance, and increase the amount of dust, can be said to be the preferred filter material of various types of filter equipment
Next we come to have a look the principle of filter, HEPA filter, dust particles in the air with air as the inertial motion or Brown movement without rules, and moved by some field force. When the movement of particles hit the other obstacle, gravitational particles and obstacle between surfaces make it stick in the barrier, this is the process of pollutants by adsorption.
In addition, when the suspended particles in the air, microbes with gas flow after the device, the HEPA filter using the filter is composed of a messy interwoven fibers, so these messy interwoven fibers also formed many barrier to particle, suspended particles, microorganisms are filtered to the surface of fiber the material, and the space between the fibers allow air to flow smoothly through, in this way, after the completion of the filtered air at the same time, the service life of the equipment is also very good guarantee!
Filtration efficiency stability, small resistance, large dust holding capacity, the replacement is convenient, strong adaptability of the device in many fields have made extensive use of, at present in the ventilation engineering, hospital operation room and asepsis room, food factory, pharmaceutical factory, central air conditioning, air cleaner and the air cleanliness the strict requirements of occasions, the HEPA filter are missing.
Finally, we say that when using the equipment should pay attention to what the index:
1, filtration efficiency: ≥ 96%;
2, resistance: ≤ 50Pa;
3, let the dust in the air: 123.9m3/h measured under the condition of dust holding capacity is greater than or equal to 25g;
4, the use of life: 2 years.
In the mastery of these so much about HEPA filter of knowledge, for the device you Is it right? Feel more understand? It can be said that this filter is absolutely cannot lack in our industry!
