1. Reinforced Waterproof Paper Frame, Deformation Resistant: Adopts thickened waterproof hard paper frame with neat cutting edges, excellent air tightness and perfect fitting installation without air leakage, compatible with most standard filter equipment.
2. Standard G4 Filtration Grade, Stable Performance: Compliant with EU G4 primary filtration standard, efficiently intercepts large particles above 5μm, delivering reliable pre-filtration performance for most industrial and commercial ventilation scenarios.
3. Low Wind Resistance & High Dust Holding, Energy Saving: Adopts fluffy customized synthetic fiber media with superior air permeability, low wind resistance that does not affect fan airflow. Larger dust holding capacity extends replacement cycle and reduces equipment energy consumption and maintenance frequency.
4. Disposable Design, Low Maintenance Cost: No water cleaning required. Direct replacement after blockage saves labor time, avoids secondary pollution and reduces daily operation cost.
5. Full Size Range & Customization Available: Standard sizes in stock with fast delivery. Custom non-standard length, width and thickness sizes are supported to match diverse equipment and filtration requirements.
6. Ultra-High Cost Performance: Compared with metal and aluminum frame filters, paper frame filters have lower costs, perfectly suitable for large-area and high-frequency replacement industrial scenarios with more favorable bulk purchase price.
