What are the characteristics of medical medium-efficiency filter equipment?
What are the characteristics of medical medium-efficiency filter equipment?What are the characteristics of medical medium-efficiency filter equipment? In the three-level filtration system of the dust-free workshop, the medium-efficiency bag filter plays a "bridging" role. The characteristics of the medium-efficiency bag filter in the dust-free workshop mainly include the following, maintaining the excellent air quality in the dust-free workshop.Medical medium-efficiency filter equipment filters dust with a diameter between 1-5μm. The dust-free workshop generally adopts a three-level filtration system. When air enters the filtration system, dust particles with a diameter of more than 5μm are first intercepted and blocked by the primary filter, and the remaining dust with a diameter of less than 5μm enters the medium-efficiency filter. Medical medium-efficiency filters are generally bag filters, located between the primary and high-efficiency filters. When dust touches the fiber filter material in the filter bag of the medium-efficiency bag filter in the dust-free workshop, it will deviate from the direction and collide under inertia, thereby settling in the filter bag, intercepting dust particles with a diameter of 1-5um. After two layers of interception by the primary filter and the medium-efficiency bag filter, only dust particles with a diameter of less than 1um reach the high-efficiency filter, which can effectively extend the service life of the high-efficiency filter. To achieve better-filtering effects, medium-efficiency bag filters in dust-free workshops usually use chemical artificial fibers containing static electricity as filter materials. When air-carrying dust particles enter the filter bag, it can not only effectively intercept dust particles larger than 1μm by fiber density, but also allow particles that collide with static electricity fibers to carry different charges. When these charged dust particles collide with smaller dust in the medium-efficiency bag filter, they can attract and bond with each other to form larger particles, so that some dust smaller than 1μm can also be intercepted by the bag filter, further reducing the burden on the high-efficiency filter. Different colors represent different filtration efficiencies. Compared with bag filters of other efficiencies, medium-efficiency bag filters in dust-free workshops usually have a variety of filter bag colors. This is not for beauty, but to reflect the difference in different filtration efficiencies through color. The over-reduction efficiency that different bag overfill manufacturers can provide is also different. The white mixed bag filter produced by it has a filter efficiency of F5 (40~60%); the green bag filter has a filter efficiency of F6 (60~80%); the pink bag filter has a filter efficiency of F7 (80~90%); the yellow bag filter has a filter efficiency of F8 (90~95%); the yellow-white bag filter has a filter efficiency of F9 (95~98%). To meet the needs of various industries for cleanroom air quality, the process of dust-free workshop medium-efficiency bag filters is also constantly evolving and upgrading. At present, many manufacturers use ultra-fine synthetic fibers to form filter materials using special weaving methods to avoid the discomfort caused by old glass fibers to the human body. |
