The structure of the air filter frame mainly used: aluminum profiles, multi-layer frame, aluminum frame, galvanized steel frame, the use of up to aluminum alloy frame, the main production into a cube-shaped structure. air filter materials Media: Multi-use of glass fiber, chemical fiber gradually in use, at present, some foreign manufacturers with PTFE electrostatic fiber (electret) to create high-efficiency filter, commonly known as PTFE. Efficient structure and there is no separator and separator. No separator mainly uses hot sol as separator of filter element to facilitate mechanized production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency and even wind speed. At present, large quantities of air filters required for the clean workshop mostly adopt the structure without a partition board. A partition efficient, multi-use aluminum foil, made of paper folding as a filter separator, the formation of air channel. Separators are made of high-quality kraft paper, hot-roll forming or using offset paper as separator.

Currently, most filters use double-sided coated paper as separator, the main purpose is to prevent the separator from being affected by hot and humid effects of shrinkage, which emit particles. However, according to my company’s experience over the years, when the temperature and humidity changes, this separator paper may have larger particles emitted, resulting in clean factory cleanliness test failed. Therefore, for cleanliness demanding places, customers should recommend the use of high-performance air filter without partition. Separators abroad, the price of filters is higher than the price without separator, so there is less space for foreign use separator. In addition, the V-shaped passage without the baffle filter further improves dust containment uniformity and prolongs service life compared to a rectangular passage with baffle filter. Ventilation filter without baffle to avoid the use of metal parts, easy disposal, in line with the increasingly stringent environmental requirements. In addition to certain high temperature and high safety requirements of special occasions, no separator filter can replace the separator filter.
