Introduction to the structural characteristics of flat plate primary air filters

Plate-type primary air filters are suitable for fresh air and return air filtration in air system, and pre-passing of local high-efficiency filtration device. Plate-type primary air filter performance characteristics: 1, the filtration efficiency of ≥ 5.0μm particles in 40% ~ 60%. 2, the use of special bulky high-flux and low-resistance chemical fiber cloth as a filter material, large dust capacity. 3, There are galvanized steel plate, aluminum alloy or plastic frame. Structural characteristics of flat-plate primary air filter: assembled into a pipe form, leaving flanges at the front and rear, easy to connect with the air ducts of centralized air conditioning system. Several filters are arranged and combined according to the required air volume, and an inspection door is left at the bottom (or side) of the filter section for overhauling and replacing the filter. Rough and medium efficiency section is only suitable for the filtration of new air. Sub-high efficiency filtration section is characterized by high efficiency and low resistance. The initial resistance under the rated air volume is ≤90Pa, and the filtration efficiency for dust particles with a particle size of 0.5μm or above is 95%...
