F5-F9 Synthetic Fiber Bag Filter

Synthetic fiber bag filter adopts high-performance synthetic fiber media to maintain stable filtration under humid conditions, high air volume, and heavy dust load. Each filter bag is individually supported by a rigid grid and secured inside a robust U-shaped frame, effectively preventing bag leakage and improving overall structural reliability. With more uniform airflow distribution, the bags can fully expand, reducing operating resistance, efficiently capturing fine particles, and extending the service life of the filter.

Humidity Resistance: ≤100%RH
Filtration Object: ≥ 15 μm coarse dust

Synthetic Fiber Pocket Filter features

Low Pressure Drop and Energy-Efficient Design: the synthetic bag filter features a low pressure drop, which effectively reduces HVAC system energy consumption and enhances overall energy efficiency.
High Dust-Holding Capacity and Long Service Life: premium synthetic fiber media significantly boost dust-holding capacity, reducing the frequency of replacements.
Consistent Filtration Efficiency: efficiently captures PM10 and PM2.5 particles while maintaining stable performance throughout its service life.
Lightweight Structural Design: facilitates easy installation, maintenance, and replacement, thereby lowering labor and operational costs.
Uniform Airflow Distribution: the multi-pocket structure, combined with internal support grids, minimizes resistance and optimizes airflow.
Adaptability to Demanding Conditions: maintains stable performance even in environments characterized by high humidity, high airflow, and heavy dust loads.
