Dust medium efficiency air filters can be used in many industries, such as central air conditioning ventilation systems, such as pharmaceutical, hospital fields, in addition to electronics and food industries. It is often combined with high efficiency air filters to achieve front-end filtration levels, so that the load of the entire filter is reduced and the life is extended.
The filter material is special, not only non-woven fabric, but also added glass fiber, which is now a popular material, especially environmentally friendly, from the frame point of view, it uses cold plate spray, and some also use galvanized sheet. The filter particle size can meet the requirements of most customers, ranging from 1 to 5um, if compared according to the colorimetric method, the filtration efficiency can reach 60%, and some can reach 95%.
From the market classification point of view, dust removal medium efficiency air filter has a bag structure, there are non-bag structure, the former model is more, the latter has plate medium efficiency filter, diaphragm medium efficiency filter, and the combined medium efficiency filter also belongs to this category.
In the purchase process, people can consider the rated air volume, filtration efficiency and other factors, but also consider the dust capacity, resistance and other factors. At present, there are production standards in the industry, and specific reference to relevant standards for inspection helps to select products.
