Performance Features
1.Low resistance, high air volume, long service life, large filtration area, and high dust-holding capacity.
2.Sturdy structure, capable of normal operation under ultra-high air volume conditions.
Application Fields
1.Primary filtration for industrial and civil ventilation systems;

2.pre-filtration for centralized HVAC systems in cleanrooms.
Design Features
1.Box filters use synthetic fiber and non-woven filter materials to create replaceable filter cartridges, reducing operating costs.
2.High-strength outer frame with added support design enhances the durability and strength of the filter.
3.Available in both "flanged" and "non-flanged" configurations.
4.A sealing gasket can be optionally installed between the box-style folded filter and the fixed frame to prevent air leakage.
5.Filtration efficiency grades: G1, G2, G3, G4 (EN779).
