G4 F5 F6 F7 F8 F9 Synthetic Fiber Roll Pocket Filter Material Air Filter Paper Media for HVAC Ventilation

Our bag-type air filter media material specifications are as follows: The outer layer is made of 100% high-strength non-woven fabric, with color customizable according to customer requirements. The dual-component (PP+PET) layer utilizes a “Z”-shaped blend of ultra-fine meltblown fibers and PET fibers, providing higher filtration efficiency, excellent compression resilience, higher air permeability, and dust holding capacity while reducing pressure drop during use. This innovative filter media is designed for applications requiring both high dust holding capacity and low resistance. The inner non-woven fabric layer, made of needle-punched or composite non-woven media, filters larger particles at a lower initial pressure drop, enhancing maximum dust holding capacity and extending the filter bag’s service life. The central partition ensures that air pressure is evenly distributed throughout the entire bag, improving filtration performance.
