In purification equipment, filters are of crucial importance. Guangzhou Cleanroom Construction Co., Ltd., which specializes in the production of purification equipment, deeply understands that choosing the right filters and properly controlling their replacement cycle is of great significance for the efficient operation of equipment and the cleanliness of the environment. Now, let's explain the relevant knowledge for you.

Primary efficiency filters have a simple structure and low cost. They mainly filter large - particle dust such as dust and hair. Although their filtration efficiency is not high, they can effectively protect the subsequent precision filters. At the entrances of ordinary industrial plants, commercial buildings, and places with low purification requirements, primary efficiency filters can initially purify the air and reduce the subsequent filtration pressure. For example, in factory workshops, they can intercept a large number of large - particle pollutants from the outside, preventing them from entering the workshop and affecting production equipment and product quality.

Medium efficiency filters have a higher filtration accuracy than primary efficiency filters and can capture small - particle dust, pollen, etc. They are often installed in the intermediate filtration stage of air - conditioning systems or in places with certain cleanliness requirements, such as ordinary hospital wards and school classrooms. Medium efficiency filters can further purify the air, relieve the pressure on high - efficiency filters, and extend their service life, creating a relatively clean indoor air environment.

High - efficiency filters have an extremely high filtration efficiency and can capture dust particles, bacteria, etc. as small as 0.3 microns or even smaller. They are used in places with extremely high cleanliness requirements, such as pharmaceutical workshops, electronic chip manufacturing workshops, and biological laboratories. In the pharmaceutical industry, they ensure that the air is sterile and dust - free during the drug production process, prevent drug contamination, and guarantee the safety and effectiveness of drugs.

For ordinary office environments, a combination of primary and medium - efficiency filters can meet the daily air purification needs, remove common pollutants, and create a comfortable atmosphere. However, for places with extremely strict cleanliness requirements, such as medical operating rooms and semiconductor manufacturing workshops, high - efficiency filters must be equipped, and even multi - stage high - efficiency filtration systems are required to ensure that there are almost no harmful particles in the air.

Different purification equipment is suitable for different filters. When selecting filters, parameters such as the air volume and air pressure of the purification equipment should be fully considered. Equipment with a large air volume needs to select filters with a large filtration area and low resistance to ensure the normal operation of the equipment without affecting the filtration effect. If the filter does not match the equipment, it will lead to poor equipment operation, increased energy consumption, and failure to achieve the expected purification results.

In heavily polluted industrial areas, such as near steel mills and cement plants, the replacement cycle of filters in purification equipment will be significantly shortened. A large amount of dust and particulate matter in the air will quickly clog the filters and reduce their filtration efficiency. The primary efficiency filter that was originally replaced once a year may need to be replaced every 2 - 3 months in such environments. In contrast, in relatively clean indoor environments, such as high - end office buildings and libraries, the filter replacement cycle can be appropriately extended.

By observing the operating parameters of the purification equipment, such as pressure difference changes, the degree of filter clogging can be judged. When the pressure difference at both ends of the filter reaches the upper limit specified by the equipment, it indicates that the filter is severely clogged and needs to be replaced in a timely manner. In addition, if there is obvious dust accumulation on the surface of the filter and the color darkens, it also means that the filter needs to be replaced.

Choosing the right filters and mastering the replacement cycle is the key to enabling purification equipment to 发挥 its best performance and maintain environmental cleanliness.
