High efficiency filter is also called high efficiency filter/high efficiency filter/HEPA filter/air filter/high efficiency filter/filter element, etc., as we all know, today's supply market environment in China, most of the Red Sea, supply products, suppliers, fierce competition, uneven, a wide range of air filters. So how to choose the right air filter, we must proceed from the actual, high efficiency air filter installation and purchase points:
High efficiency filter is also called high efficiency filter/high efficiency filter/HEPA filter/air filter/high efficiency filter/filter element, etc., as we all know, today's supply market environment in China, most of the Red Sea, supply products, suppliers, fierce competition, uneven, a wide range of air filters. So how to choose the right air filter, we must proceed from the actual, high efficiency air filter installation and purchase points:
High-efficiency filter in a certain environment, the end air filter element affects the cleanliness of the air sent out. The front-end air filter at all levels protects the end air filter and prolongs the service life of the end air filter to ensure Its normal work. When choosing an air filter, it must be considered in many aspects, and the appropriate air filter must be selected reasonably according to the specific situation. The selection principles are as follows:
Correctly select the characteristics of the air filter. The characteristics of the air filter are mainly filtration efficiency, resistance, penetration rate, dust holding capacity, filtration wind speed and air volume. When conditions permit, filters with high efficiency, low resistance, large dust holding capacity, moderate filtering wind speed, large processing air volume, convenient manufacturing and installation, and low price should be selected as far as possible. This is the economic analysis needs of considering one-time investment and two-time investment and energy efficiency ratio when selecting air filters.
According to the indoor requirements of clean purification standards, determine the end of the air filter efficiency, reasonable selection of air filter combination series and the efficiency of all levels. If general purification is required indoors, primary effect filters can be used. If medium purification is required indoors, primary effect and medium effect two-stage filters should be used. If ultra-clean purification is required indoors, primary effect, medium effect and high efficiency three-stage purification filtration should be adopted, and the efficiency of all levels of filters should be reasonably and properly matched. If the efficiency of adjacent two-stage filters is too different, then the former filter cannot protect the latter filter.
Analyze the nature of the dusty gas. The nature of the dust-containing gas related to the selection of air filters is mainly temperature, humidity, acid and alkali, and the amount of organic solvents. Because some filters are allowed to be used at high temperatures, and some filters can only work at room temperature and normal humidity, and the amount of acid-base and organic solvents in the dust-containing gas has an impact on the performance and efficiency of the air filter.
Correctly determine the dust content and dust particle characteristics of outdoor air. Because the filter is to filter and purify the outdoor air into the room, the dust content of the outdoor air is a very important data. Especially in the multi-stage purification and filtration treatment, when selecting the pre-filter, the use environment, spare parts cost, operation energy consumption, maintenance and supply and other factors should be considered comprehensively.
