Introduction:
Bag filter is a common and highly efficient medium-efficiency filter.
Its core feature lies in the filtration structure composed of an internal support frame and multiple filter bags. This design not only enables it to have a large filtration area and effectively capture particles of 1-5 microns in the air, but also achieves excellent comprehensive performance through a reasonable structure.

Performance Features:
![Bag Filter Bag Filter]()
1.Large dust holding capacity and long service life: The unique bag structure provides a huge surface area, which can accommodate more dust, significantly extending the replacement cycle and reducing maintenance costs.
2.Low operating resistance and energy saving: The increased filtration area enables smoother air flow, with small and stable initial resistance, which helps to reduce the energy consumption of the air conditioning system.
3.Stable filtration efficiency: The multi-bag design effectively utilizes the entire depth of the filter material for filtration, ensuring more lasting efficiency.
4.Sturdy structure and strong applicability: The sturdy metal support frame prevents the filter bag from deforming in strong wind, ensuring the filtration effect and usage safety.
Main application sites:
1.Commercial and public buildings: Medium-efficiency filter sections of central air conditioning systems in office buildings, shopping malls, hotels, and hospitals.
2.In the industrial field: Pre-filtration for process environments with requirements for air cleanliness, such as painting workshops, electronics, pharmaceuticals, and food.
3.Equipment protection: As a pre-filter for high-efficiency filters (HEPA), it effectively extends their service life.
