Flat plate air filter
Flat plate air filterThe following is a detailed introduction to the flat air filter:Structural characteristics Frame: usually use a solid plate aluminum alloy frame, there are also paper frames, galvanized plate frames, stainless steel frames, and other materials optional, the air surface plus diamond mesh, to ensure that the filter in the poor working environment is not deformed or damaged, some can also be disassembled design, easy to replace the filter material. Filter material: High-quality polyester synthetic fiber, synthetic glass fiber, non-woven fabrics, and other materials with fluffy and denser fiber structures are used to ensure a higher dust collection rate and larger dust capacity.  Working principle Inertia effect: Large dust particles do inertial motion in the air stream because the inertia can not bypass the fiber and directly hit the fiber is intercepted. Interception effect: Small, light dust moves with the air stream, and when the air stream brushes against the fiber surface, the dust is intercepted. Diffusion effect: Dust smaller than 1 micron due to the impact of air molecules, do irregular diffusion movement, hit the fiber will be captured. Electrostatic effect: Filter fibers and air dust particles may carry static electricity for various reasons, and dust particles will be attracted to the fibers. Performance characteristics Economical and practical: the production cost is relatively low, the filter material can be cleaned and reused several times, and the service life is long, which can effectively reduce the use cost. Simple structure: lightweight, easy to install and maintain, good versatility, suitable for a variety of filtering scenarios. Small resistance: the air volume is large, which can ensure the normal operation of the ventilation system and will not cause too much obstruction to the airflow. Stable filtration efficiency: In the early and late stages of use, the filtration efficiency changes relatively small, and the impurities in the air can be continuously and stably filtered. Application field Civil buildings: Ventilation and air-conditioning systems of large civil buildings such as office buildings, conference rooms, hospitals, shopping malls, airports, etc., provide people with a clean and healthy air environment. Industrial field: Pre-filtration of centralized ventilation and air conditioning systems in ordinary industrial plants or clean rooms, such as electronics factories, pharmaceutical factories, and other places with high air cleanliness requirements, can protect the precision equipment and production process at the back end from impurities such as dust. Other fields: It can also be used for pre-filtration of large air compressors, intake filtration of filter rooms of centrifugal compressors, and crude filtration of dust removal and oil removal of various air conditioning systems. Selection and maintenance Selection: According to the use of the environment, air volume requirements, filtration grade requirements, and other factors choose the appropriate flat type air filter, such as in a dusty industrial environment, should choose a higher filtration efficiency, large dust capacity model; In clean rooms with very high air quality requirements, a higher grade of filter is required. Maintenance: Regularly check whether the filter plastic net is damaged, whether the air inlet surface is blocked by debris and whether the filter material surface is damaged. If the blockage should be removed in time, the filter material surface damage is serious, and a new filter material or filter must be replaced. Under the conditions of rated air volume use, the filter should be replaced in 4-6 months, or when the resistance of the filter reaches 350Pa or more, the filter must also be replaced. |
