High efficiency air filter structure material selection

Structure: The main use of the frame: aluminum alloy profile, multi-layer plate frame, aluminum plate frame, galvanized steel plate frame, the use of Z aluminum alloy profile frame, the main production of a square shape structure.

Filter media: the use of glass fiber, chemical fiber gradually in use, some foreign manufacturers with electrostatic PTFE fiber (electret) manufacturing high efficiency filter, commonly known as PTFE.

Efficient structure and there is no partition and partition. Thermal sol is mainly used as separator of filter element without separator, which is convenient for mechanized production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency and uniform wind speed, and a large number of filters required by clean workshop are mostly used without clapboard structure. With high efficiency, aluminum foil and paper are mostly used as folded filter separator to form air passage. Separators are made of high quality kraft paper, hot rolling or uncoated paper. The main purpose is to prevent the partition board from shrinking under the influence of cold, heat, dry and wet, so as to emit particles. However, when the temperature and humidity change, the separator paper may have larger particles distributed, resulting in the cleanliness test of the clean workshop is not qualified. (There have been several customer complaints about this) so, for places with higher cleanliness requirements, customers should be recommended to use HEPA filters without partitions. The price of the foreign separator filter is higher than the price of the non-separator, so there are fewer places to use the separator abroad. In addition, compared with the rectangular channel with baffle filter, the V-shaped channel without baffle filter further improves the dust uniformity and prolongs the service life. No partition filter for ventilation can avoid the use of metal parts, easy to waste treatment, in line with the increasingly strict environmental requirements. In addition to some high temperature resistance and high safety requirements of special occasions, no separator filter can replace the separator filter.
