How to use and replace air filters
How to use and replace air filtersI. Use of air filters1. No matter which grade of the filter is used, it is necessary to use it within the proper scope, if it is not used properly, it will not only play the role of filtration but also may produce the opposite effect. 2. First of all, let's talk about the coarse filter, which is used as a pre-filter, its role is to filter the larger particles of pollution, to protect the normal operation of many devices afterward, it should be noted that this equipment can not be used as a terminal filter. 3. Medium-effect filter is usually set in the positive pressure section of the system, its main role is to protect the subsequent high-efficiency filters, etc., can effectively remove small and medium-sized pollution particles ≥ 1.0μm, can not be used as a pre-filter and can not do the terminal filter. 4. After saying is the high-efficiency filter, which is the terminal filtration equipment of the whole purification system, can filter 0.1μm pollution particles, is the general clean room must filter. II. Replacement of air filters 1. No matter what type of filter after a period of operation, when its resistance reaches the final resistance Hz, it needs to be replaced, otherwise its performance will be substantially reduced and cannot play its proper role, and even affect the normal operation of the whole system. 2. For coarse and medium efficiency filters, some are for one-time use, and some can be cleaned and used again, but the resistance of coarse and medium efficiency filters after cleaning is much greater than the initial resistance. 3. For high efficiency and super high-efficiency filters are for one-time use and should be replaced in time after reaching the final resistance value of the equipment. |
