High-efficiency Bag-Type Air Filter Structure and Principle: The outer frame can be made of aluminum, paired with superior fluffy multi-layer synthetic fiber filter material, achieving a high degree of filtration efficiency. The synthetic fiber filter material has one layer to capture larger particles in the air, while the finer second layer enhances the filter's stability and prevents smaller dust particles from floating in the air. This two-layer design ensures low initial resistance and high dust capacity. Additionally, with its unique bag-type structure, it ensures an even airflow filling the entire bag, effectively preventing overcrowding between bags or leakage, thereby reducing resistance and maximizing dust capacity. The reinforcing wire serves to prevent the filter from deforming or coming out of the frame under poor working conditions.

Product Features:

Medium-efficiency bag air filters are divided into four efficiency grades:

F5 Medium Efficiency Bag Filter, white color, efficiency 40% ~ 60%

F6 Medium Efficiency Bag Filters, Green, Efficiency 60%~80%

F7 medium efficiency bag filters are pink in color with an efficiency of 80%~90%.

The F8 medium-efficiency bag filters are yellow in color and have an efficiency of 90% to 95%.
