With the development of social economy, people's requirements for air quality have become strict. Air filters are important components for purifying air. They capture and adsorb dust particles or gases of different diameters in the air, so as to purify the air. Air filters can be classified according to filtering efficiency, materials used and manufacturing methods. It is commonly used to divide according to efficiency. It can be divided into primary filter, medium efficiency filter and high efficiency filter, among which medium efficiency plate filter is the most widely used. Use of medium efficiency plate filter: medium filtration of filter section in general ventilation air treatment equipment or fresh air system. Features: low cost, good filtering effect, self replacement. Medium efficiency filter is generally used for medium filtration of filtration and air suction system in air handling equipment, as well as high temperature resistant air filter. It is made of stainless steel with a high temperature resistant 250-300 ° C filtration efficiency. It is characterized by easy and simple replacement of filter materials. The paper frame has the same initial effect, low price, light weight, good versatility and compact structure. It is a general air purification in the application electronics industry, pharmaceutical industry, mechanical instrument industry, metallurgy industry, petrochemical industry, light industry, food processing industry and other fields. It is characterized by high efficiency, large adsorption capacity and relatively small space occupation.
