The bag filter adopts a multi-layer filter material structure and is composed of multiple "filter bags". Each filter bag can effectively capture particulate matter in the air. The standard configuration includes 3 to 12 filter bags, and the length of each filter bag can be customized. By increasing the number and size of filter bags, the filtration area can be expanded, thereby increasing the dust holding capacity and significantly extending the service life of the filter.
High-efficiency bag filters are mainly divided into two materials: glass fiber and synthetic fiber. As a traditional filter material, glass fiber has excellent durability and its service life can usually reach four times that of synthetic fiber. However, it should be noted that although synthetic fiber is slightly inferior in durability, its unique antibacterial properties make it the first choice for places with strict requirements on bacterial control, such as hospitals and research centers.
This type of filter is widely used in places with strict requirements on air quality, including: medical institutions, scientific research laboratories, food processing workshops, pharmaceutical factories, data centers, electronic clean workshops, airport terminals and other public buildings HVAC systems, which is an ideal choice for ensuring air cleanliness.
