What is the difference between flat air filters and other types of filters?
What is the difference between flat air filters and other types of filters?Flat-type air filters are often compared with folding-type, bag-type, high high-efficiency air filters, they have differences in structure, filtration efficiency, resistance, dust capacity, application scenarios, etc., and the following is the specific analysis:Compared to a folding air filter Structure: The flat air filter structure is simple, flat, flat filter material; The folding air filter folds the filter material into a pleated shape to increase the filtration area. Filtration efficiency: Under the same filter material, the folding air filter can capture more dust particles because of the large filtration area, and the filtration efficiency is relatively high; The flat type is relatively low, but can meet the general air filtration needs. Resistance: The airflow through the flat air filter is smoother, and the resistance is relatively small; Due to the folding of the filter material, the airflow channel is relatively complex, and the resistance is slightly larger, but it is generally within an acceptable range. Dust capacity: The folding air filter has a large filtration area, the dust capacity is usually higher than that of the flat air filter, and the service cycle is relatively long. Compared with bag air filter Structure: The flat-type air filter is a flat-type structure, and the bag-type air filter is composed of different forms of filter bags, usually multiple filter bags combined together. Filter efficiency: The bag air filter can achieve medium and efficient filtration effect according to different filter materials and designs; Flat type air filters are generally based on initial and medium effect filtration, and efficient ones are relatively few. Resistance: The resistance of the bag air filter rises faster with the increase of dust capacity; Flat air filter resistance rises relatively gently. Dust capacity: The filter bag space of the bag air filter is large, and the dust capacity is generally much larger than that of the flat air filter, which can maintain a better filtration effect for a long time. Compared to HEPA filters Structure: Flat air filter structure is relatively simple, and the material is common; Hepa filters usually use finer fiber materials and may have multi-layer composite filter layers on the structure to achieve efficient filtration. Filtration efficiency: The filtration efficiency of a high-efficiency air filter for particles with a particle size of 0.3 microns or more can reach 99.97%, and can filter out extremely fine dust and bacteria; Flat air filters are mainly used to filter impurities such as dust or larger particles, and the filtration efficiency is usually about 30%-80% (initial effect) or about 60%-95% (medium effect). Resistance: high-efficiency air filter due to high filtration accuracy, the airflow through the resistance is larger; The resistance of the flat-type air filter is significantly less than that of the high-efficiency air filter, which can ensure a large ventilation volume. Dust capacity: The dust capacity of the high-efficiency air filter is relatively small because its main function is high-precision filtration, rather than a large amount of dust; The dust capacity of flat air filters varies according to specific specifications and application scenarios but is generally larger than that of high-efficiency air filters. |
