What are the differences in the diversity of materials used in cleanroom HEPA filters?The use of filters is mainly for the clean room to filter out air pollutants and dust, according to the different standards of particle size, it is divided into primary filters, medium-effect filters, high-efficiency filters, etc., of which, for some clean grades or high requirements of the environment, commonly used is high-efficiency products, then what is the quality of high-efficiency filters in clean areas, and what is the difference between the classification?The clean area high-efficiency filter is divided into five categories: high-efficiency filter without partition, high-efficiency filter with partition, V-type high-efficiency filter, liquid tank high-efficiency filter, high-temperature resistant high-efficiency filter, and the use of two high efficiencies is without partition and partition filter, and many users who have used it, will say that the performance of high-efficiency filter without partition is better than a high-efficiency filter with partition this has a certain relationship with the high-efficiency filter material The specific details are as follows: Because of the clean area high-efficiency filter material using aluminum foil, and paper material for separation, to form a certain empty channel, for paper material, a high-quality point will choose kraft paper, the need for hot roll forming most of the choice of offset paper, and most of the choice of double-sided glued coated paper, these types of paper material in the temperature or humidity when there are drastic changes will emit a lot of very large particles, cleanliness will also reach The cleanliness level is therefore not as high as required. In addition, the high-efficiency air filter has a small footprint, low weight, easy installation, high filtration efficiency, and stable airspeed. Therefore, the performance of non-spacer HEPA filters is better, the price of non-spacer filters is relatively low, and the materials used do not use metal parts, so it is easy to dispose of the waste gas at the end of life, which is more environmentally friendly. |
